Understanding octal IP addresses
Since I couldn't find any discussion on how to decipher octal (leading zero) IP addresses, I added the link http://blog.anta.net/blog/_archives/2007/9/29/3260244.html (scroll down to the "Another URI that has been used ---" paragraph). 85.156.238.134 08:19, 30 September 2007 (UTC)

IPv6 and OS support

 * ... and an increasing range of Linux distributions include native support for the protocol ...

As far is I know casual linux distributions have been shipping with IPv6 enabled by default for several years. Of course there are special-purpose distributions that lack IPv6 among other features/packages, but these are not used by general desktop and server users. --Alvin-cs &#9993; 17:47, 25 October 2007 (UTC)

Short IP / Long IP
Hello, could someone write something about long IPs? --87.173.250.179 16:50, 4 November 2007 (UTC)
 * What some people call a "long IP" is usually just the decimal notation of the IP address. You can add that in somewhere if you like, but I'm not sure where it should go. Indeterminate (talk) 06:44, 18 December 2007 (UTC)

Access page via i.p. adress
I don't know if this is a useful to be included in the article or not, but how does one go about accessing a web page using the i.p. adress of that web page not the url?Veggieburgerfish (talk) 10:30, 28 January 2008 (UTC)
 * Well... I guess it couldn't hurt to mention in the article that IP addresses are sometimes used in URLs. Anyway, you're confusing your terms a little bit: when typing a url (you know, in the address bar), you can type either the hostname (http://www.wikipedia.org) or the ip address (http://91.198.174.2). Hope that helped. Indeterminate (talk) 10:58, 3 February 2008 (UTC)

IP addresses for USA
This page says US has almost 40 per cent of all IP addresses worldwide in 2007. Is there any way to know actual number of IP addresses worldwide? Another page gives different figures for UK.

My guess: US has almost 2 billion IP addresses while the rest of the world has another 3 billion IP addresses, after reckoning IPv4, IPv6, DHCP, NAT, RFID tagged devices, SNMP-enabled (HVAC) devices, IP-enabled devices (apart from computers).Anwar (talk) 21:38, 2 April 2008 (UTC)

 * Treatment of "static" vs. "dynamic" in the article is very vague, and not actually correct, depending on circumstances. I will try to refine it soon. With DSL you can have either static or dynamic address, depending on how your ISP installs/configures your router. Kbrose (talk) 17:05, 19 July 2008 (UTC)

A very important and unanswered question
I have not found the answer to the question: What is the composition of the IP address? What do those blocs of numbers indicate? It would be very much appreciated if you include that information under the IP page. Thank you!--Reinaldo Contreras (talk) 01:16, 28 February 2009 (UTC)

Duplicated material
Much of the material on this page is duplicated in the extensive Addressing section of the IPv4 article. IPv4 address redirects to this section of the IPv4 article. Over on the IPv6 side, things are a bit more reasonable - there is a summary section with pointer to the IPv6 address article. We can't exactly follow that model here because this article is trying to cover both IPv4 and IPv6 addresses.

I suppose what we can do is create a new IPv4 address article and merge this article and the Addressing section into it. The Addressing section would be rewritten as a summary a la what we see in the IPv6 article. The This article can then become a short introduction to the concept of IP addressing and point to IPv4 address and IPv6 address as main articles. Any other ideas? --Kvng (talk) 15:01, 18 January 2010 (UTC)

Number of Networks for Class C in Historical classful network architecture
The article states that there are 2,097,151 (221-1) networks available in Class C network. However, the reason for subtracting one Class C network from 2,097,152 (221) is not explained anywhere, whereas the reason for subtracting two networks from Class A is clearly explained in the article. In fact, There is no mention of that one unused network for Class C in the article Classful network, while the two unused network for Class A is also explained in that article.

The only explanation that I could find for subtracting one network from Class C is due to 192.0.0.0 being used for private networking, but that would mean that other networks would need to have one less network as well.

Can someone add a valid reason behind stating that 2,097,151 (221-1) networks are available for Class C network? Otherwise we would have to change it to 2,097,152. —Preceding unsigned comment added by Zeraxeal (talk • contribs) 07:03, 26 March 2010 (UTC)

List of web-based tools for determining one's IP address on the global public Internet
Hi. In this edit, removed the list of web-based tools for determining one's IP address on the global public Internet as "spammy". "http://en.wikipedia.org/Special:Mytalk (only if you are not logged in)" is "spammy"? Really? Having verified that all of the URLs on that list work for the designated purpose with a minimum of fuss (except nine that did not work, one that is blacklisted here, and five that included popups, excessive ads, a need for an unused language pack, misleading prepended zeros, and a frightening unauthorized access prohibition), I am about to undo the "rm spammy list" portion of that edit. — Jeff G. ツ 18:10, 25 May 2010 (UTC)
 * What is the reason for having this long list? It seems to conflict with WP:EL and WP:INDISCRIMINATE. Johnuniq (talk) 02:23, 5 June 2010 (UTC)
 * I have addressed the length of the list by splitting it into two columns in a table, and collapsing the table. The URLs are accurate and on-topic, in compliance with WP:EL.  Which specific part of WP:INDISCRIMINATE are they out of compliance with?    — Jeff G. ツ 17:32, 5 June 2010 (UTC)
 * Formatting the information is not the issue. Wikipedia is often used to promote websites by people who add links in articles (I'm not suggesting that you are doing that, but a list like this is an invitation for anyone to add further links, with no discrimination regarding which links are particularly pertinent to the article). WP:EL suggests that there should be a reason to add a link, rather than needing a reason to remove one. From WP:NOTDIRECTORY we have the general rule that Wikipedia is not intended to provide extensive lists. Why should this article have all those links? I suppose I should ask for opinions at WP:ELN. Johnuniq (talk) 02:49, 6 June 2010 (UTC)

clarification of what this means please
in my view, the whole tone of this article is too "geeky" for such an important public topic.

I have a simple question - and I would expect wikipedia to answer this immediately as a yardstick for the quality of the article. question:

is the IP address my laptop, or the internet cafe I am using?

So if I move to another internet wifi, do I comment on wikipedia, or the other basic uses of IP address, from the same IP address or not?

Secondly, IP address crops up again and again as IMPORTANT - for example wikipedia logs your IP address if you are "anonymous" WHY? this is a critical and unique identifier of who is doing what on the internet, and the only thing that enters the real world of practicality identity and law - I believe the police may use IP addresses for finding who is reading certain websites, or you may be giving away details of your sexual preferences or other browsing habits, to someone, that you prefer to be secret, and you did not know.

In my opinion wikipedia needs a better quality of approach to this topic suitable for the general public and for answering these practical implications of identity and legality. How and why is it that IP addresses could lead to someone being in a law court, for example, what is the process that allows this, and makes IP address different from so many other details of computing?

94.116.38.22 (talk) 08:35, 16 July 2010 (UTC)


 * I agree that the article is technical. I've marked it as such. On the Internet your IP address comes from your ISP. Your IP will change when you move from one ISP to another (e.g. different Wi-Fi hotspot). Your IP may change over time even if you stay with the same ISP connection. For legal and tracing topics you may be interested in the Network forensics article. --Kvng (talk) 14:24, 16 July 2010 (UTC)

Bad Article, Needs Overhaul
I'm sorry, but this article is a perfect example of how Wikipedia is sometimes used as a sinkhole of esoteric information by people who know a lot about the subject but aren't particularly good at communicating it to others. After reading through several paragraphs I have learned about IPv4 and IPv6, classes (classless and classful), etc., etc. But I have yet to learn the basics...

1) What does the 32-bit number represent, how is it subdivided, and what do the subdivisions represnt? 2) How are IP addresses used in practice, and who uses them? 3) How are addresses asigned or unassigned?

I think this article needs an overhaul. The three questions above should be answered in the introduction in detail before discussing anything else. Next, some of the existing esoteric information can be presented for advanced readers. Anything dealing with the history of the IP address system should be put in a History section. Similarly, alternatives to the IP address like IPv6 or different classes should be put in a section dealing with the alternatives. After all, those are not what we use on a daily basis. Outside those sections, we should only discuss what we use in the here and now.

What say you? 155.13.48.17 (talk) 22:20, 23 August 2010 (UTC)


 * It would seem that the article defines its topic generally already in the lede. IP address is a label, it says, and that's all it is. If you want to interpret anything else into it, then you have to look for that elsewhere. The article also discusses representation in depth, and has plenty of pointers to discuss subnetting and even the obsolete class system. The lede itself talks about the use of IP addresses, what their purpose are in addressing and routing. The article further discusses assignment. The article may not have great style, but everything you asked for is clearly there. There is virtually no esoteric information in the article, what is there is pretty common stuff. Kbrose (talk) 23:35, 23 August 2010 (UTC)

History of early allocations?
Is there an article that discusses the early block allocations of IP addresses? I know some corporations like IBM were initially issued huge Class A (16,777,214 address) blocks because in the beginning, people thought there would be more than enough addresses to go around, but most of these huge blocks were eventually returned to the pool for use by others. DMahalko (talk) 03:01, 28 March 2011 (UTC)
 * AFAIR these were never "returned" as such, because some of the block was already in use and this would have required those to be re-allocated. However when class A was replaced by CIDR and /8 etc., the old big blocks were split down within IBM, DEC, HP etc. and those smaller /16s etc. that were unused (or could easily be made unused) were what went back into the pool.
 * Was it HP who ended up with the most legacy space, having acquired Apollo's, then Compaq's and (indirectly) DEC's. Andy Dingley (talk) 10:38, 28 March 2011 (UTC)

Clarification
In the image showing the IPv6 example the "2001" part should be shown as "0010000000000001". In the image the leading zeros are missing and this can cause confusion for those who convert left to right, as well as being inconsistent with the other parts of the address where the leading zeros are included. — Preceding unsigned comment added by 82.37.45.75 (talk) 12:04, 21 June 2011 (UTC)

In the table titled "Historical classful network architecture" I believe the last (7th) column heading is misleading. As the context of the article is address classes and the first column heading is "Class," the heading "Number of addresses" could easily be misinterpreted as meaning the total number of addresses in the address class. I propose that this heading be changed to "Number of addresses per network." Coming right after column 6, "Number of networks," I believe that this will be more understandable. I don't have edit rights to this page so I will have to request that someone who does make this change. Thank you, TechMaker (talk) 05:16, 27 August 2011 (UTC)

IP Addresses and Geography

Not everyone comes to read a server manual
Need a bit of "for dummies" too.

How about a simple explanation of what the number groups in the dot-decimal notation (that most average people see and make changes to upon occasion), and, for instance, why they always begin with "192". If it is in the page or links, it's too far buried in network-admin-speak for anyone who wouldn't already know the answer to ever stumble across it.

Not an uncommon issue on a wiki tech page. People are too eager to show how smart they are and forget to instruct and be helpful. Not trying to insult. If I was writing an article to convey knowledge from my "wheelhouse", I'd want to hurry and get to the good part as well. But it would be far more helpful to lay out some basics first.

Ownership, Value and Trading
I suggest that it would be useful to add information about ownership on public ranges. Once a range has been allocated out, is that range 'owned' by that organisation it is allocated to, or is it 'lent'. Some address space is now traded on closed markets (e.g. Addrex, so addresses have value.  It is suggested that ARIN/RIPE have no legal hold over addresses given our prior to their advent.

With the IPV4 ranges quickly being used-up (another topic, probably not for here) more and more cases of IP-selling, value, cost and legal ownership/rights are going to arise globally in the next few years (my subjective view only). — Preceding unsigned comment added by 62.23.212.216 (talk) 12:40, 21 August 2012 (UTC)

Interfaces have IP addresses not devices
The opening sentence is conceptually wrong. Interfaces have IP addresses not devices. This is obvious in two common situations: laptops with both an Ethernet interface and a wireless interface and a router which has a WAN interface and a LAN interface. Tarvid (talk) 06:09, 15 September 2012 (UTC)

 I tend to agree, and interfaces aren't a subset of device, as devices themselevs can be logical rather than physical. ie an interface doesn't haev to be associated to a particualr physical device.

CONTROL INDIVIDUAL SYSTEM WITHOUT IP ADDRESS --

The system control like logoff, restart, and shutdown are possible by using IP Address and/or some other commands. The commands that are based on the programming languages. Here I give an example using 'shell' command that is used in Visual Basic 6.0. Through shell command we can easily control the system. Actually the use of the command is to execute the .exe files and dos commands also. Example.

'''Logoff the system by using shell command in Visual Basic; - private sub command1_click shell("shutdown -l -f) end sub - Restart the system; - private sub command1_click shell("shutdown -r -f) end sub - Shutdown the system; - private sub command1_click shell("shutdown -s -f) end sub -''' In the above mentioned examples, the command shutdown with the parameters -l(logoff), -r(restart), and -s(shutdown) are used.  Additionally -f is used here that means force to do the tasks.

Wikipedia Is Living In A Fantasy Land
IP addresses are shared by a network. IP addresses commonly point to the wrong city. And, these days, IP addresses change for no apparent reason every so many days-to-months, assumably changed by ISPs, or some other such thing. So, why did I read sentences on this page claiming that every unique thing in the house gets it's own IP address? You lot are lying through your teeth. And, Wikipedia needs a complete overhaul to stop treating an IP address like it pinpoints who, and where someone is. (My current address says I'm way up North of where I am. I mean, way up North, in a completely different section of the entire state. It used to just commonly be in one of the neighboring cities...

An Internet Protocol address (IP address) is a numerical label assigned to each NIC ......

Also the idea of Local Area Networks vs. Internet IP values should be included early in the page.

For Example:

The Internet IP address may be a NAT to many local area IP values if a NAT is used.

 * I guess it is even worse than that because even a NIC can have multiple IP addresses. The sentence in question is in the lead and I don't think it is a good idea to detail all the wrinkles in the lead. I would propose softening the language in the lead and adding a new section to the article to comprehensively describe the types of entities which have IP addresses. ~KvnG 17:01, 16 October 2014 (UTC)

In the section Classless subnetting there is a language error in the first sentence. There third 'are' is unnecessary. The sentence reads:

IP networks are groups of adjacent addresses that are usually are routed similarly.

The correct sentence should read:

Request clarification Dec 23 2014
Wikipedia entries should be accessible to a reasonably educated layperson. Many of the medical pages are still understandable despite the fact that some go into detail.

I am reasonably Web savvy, but not a tech professional. Quite a bit of this entry is incomprehensible to me.

I recommend adding a bit more to the top. The first paragraph is good. The new second paragraph should explain simply that it reveals your ISP and what that entails. Does it give away your physical location or company? Does it change each time you move around? What does it mean if someone has your IP? These are questions that your average reader will want explained simply and clearly.

As for the rest of it, I feel it is too long and too difficult. I'll take a sentence at random: "IPv4 address exhaustion is the decreasing supply of unallocated Internet Protocol Version 4 (IPv4) addresses available at the Internet Assigned Numbers Authority (IANA) and the regional Internet registries (RIRs) for assignment to end users and local Internet registries, such as Internet service providers." If this is significant, it needs to be explained better. If it's not significant, it needs to be cut for the sake of brevity. I'm deliberately not touching the page as I am not expert in this field. Thank you! — Preceding unsigned comment added by PumpkinKitten (talk • contribs) 17:51, 22 December 2014 (UTC)


 * Thank you for your input. I have added some context to the introduction. The introduction already included "An address indicates where it is." Perhaps something more than a "See also" reference is warranted for IP address location, which redirects to Geolocation software. Re the sentence you quoted, it boils down to "We, the world at large, ran out of IPv4 addresses for the Internet Assigned Numbers Authority (IANA) to give out". That is a very big deal. Without the availability of IPv6, you may not have been able to communicate on the internet today.  —  Jeff G. ツ  (talk)   22:29, 1 March 2015 (UTC)

First paragraph of lede
"An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.[1] An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: 'A name indicates what we seek. An address indicates where it is. A route indicates how to get there.'[2]"

I have something to note about this lede paragraph, still I do not feel confident enough to change it and may not be entirely correct so I am just bringing attention to it here on the talk page.

I think it should be made completely explicit that a "device (e.g. computer, printer)" can have more than one IP address, as IP addresses are allocated to network interfaces (e.g. wireless card, Ethernet port) rather than the device per se? (ref section 4.4.2, Computer Networking - A Top Down Appreach 6e) As it stands, this first sentence implies a one-to-one relationship between IP addresses and devices such as computers and printers.

Zynwyx (talk) 11:40, 29 March 2015 (UTC)


 * The paragraph is essentially incorrect because an IP address is assigned to an interface (network card). However, the complete story would probably be unnecessarily complex in the introduction, since an accurate statement would point out that each interface can have multiple IP addresses. However, in a big-picture sense the paragraph is correct because if computer A wants to send a packet to computer B, A must find an IP for B, then send to that IP. A does not care what interface on B has the IP—from A's point of view the IP is a numerical label assigned to B, and A does not care how many IPs have been assigned to B—if the DNS query yields several IPs, A just picks one of them. Johnuniq (talk) 00:19, 30 March 2015 (UTC)


 * I agree with that the lead has the big picture correct. It also fairly accurately summarizes the body of the article which is what we want. The body does not discuss the possibility of multiple interfaces and multiple IP addresses per interface. A contribution to the body describing this would be welcome. Once that's in, we can consider adding something to the lead that summarizes it. --Kvng (talk) 13:37, 2 April 2015 (UTC)


 * Yes, looking in terms of the big picture the sentence seems adequate now. Thanks Zynwyx (talk) 19:26, 2 April 2015 (UTC)

The heading of contains a visible anchor which causes edit summaries to link to , which is a broken link (see the edit summaries shown here as an example). Please remove the extra anchor from the section heading and add it with anchor either above or below the line with the heading.

 * No, and please do not do that on other pages. If I had some time I would investigate and revert. Check the talk page and archives at Template:Anchor. The exhaustive discussions have demonstrated that there is no good place to put an anchor, and putting it in the heading is the least bad. I'm not sure if you are referring to the text that is visible in the edit summary, or to the section link in the arrow shown before the edit summary in the page history.

Public addresses
I edited the section Public addresses (diff), because I could not find a reference for the statement, "in common parlance, is synonymous with a globally routable unicast IP address." Plus, that definition, even if correct, seems overly technical for the average reader.

There are references indicating that public IP addresses are "globally unique" (see citations 20 and 21 in the article), but I could not find anything about being "a globally routable unicast IP address." Maybe they mean the same thing (I don't know), but even if they do, "globally unique" would be preferable given that it is easier to comprehend.

I included three citations, including extended quotes from each, so that readers who desire more detailed, technical information can quickly link to resources that provide it.

For those of you with the expertise to understand it all, I did find a scholarly article that uses the term, "globally routable unicast IP address." Here is the citation, and a quote from the article, for any experts who may find it helpful:


 * Otto, J. S., Sánchez, M. A., Rula, J. P., & Bustamante, F. E. (2012, November). Content delivery and the natural evolution of DNS: remote dns trends, performance issues and alternative solutions. In Proceedings of the 2012 ACM conference on Internet measurement conference (pp. 523-536). ACM. http://www.aqualab.cs.northwestern.edu/component/attachments/download/235/


 * 3.2 Measuring DNS services (p. 527)


 * Public DNS services are typically offered on BGP anycast-enabled IP addresses, allowing all users to configure the same server IP address. Probing public DNS services can present a challenge for network-level measurements, as some anycast-enabled addresses do not respond to ICMP pings.


 * To determine the recursive DNS resolver's globally routable unicast IP address so that we can probe it directly, we use a technique similar to that used by Huang et al. [9]. We operate an authoritative DNS server that answers queries with the IP address of the recursive DNS resolver sending the query. This approach works because resolvers that answer queries on an anycast IP interface use a separate unicast interface to communicate with other authoritative DNS servers; our service returns this unicast IP address for the recursive resolver. Clients send a DNS query to the public DNS service's anycast IP address and receive its globally routable unicast IP address in the DNS response; this gives the client a mapping between the public DNS service and the unicast IP address for the recursive resolver. Clients report these mappings, which enables us to identify public resolvers in our dataset.

 * The original text was correct, although unhelpful and verbose. RFC 1918 specifies which IPs should be used for private networks, and it offers thoughts on the converse, namely publicly accessible networks. Its text is not very illuminating with stuff like "All other hosts will be public and will use globally unique address space assigned by an Internet Registry." The point of a public address is that it is unique and globally routable—that just means that anyone connected to the Internet can communicate with a host that uses a public IP because the traffic will be routed between the hosts (if everything is working, and if firewalls don't block the packets). The word "unicast" is spelling out that a public IP identifies the network interface of a single host. A reference is obviously best, and there is probably a textbook that would do. The above text relating to DNS includes "globally routable unicast IP address"—that just means the public IP, that is, the IP that is accessible from the public Internet. Johnuniq (talk) 04:42, 7 March 2016 (UTC)

I find the new version neither adequate nor correct, and most of the given references not reliable either, that was just a result of random Internet crowd-sourcing without regard to quality. The new definition starts out with the undefined term external facing, which apparently implies quite a bit of network architecture that is not explained and actually has not much relevance to the subject matter. In fact, in many large-provider networks, such as consumer cable systems, public addresses don't face externally at all, it could be stated that they rather face toward the private network of the provider, not at all onto the open Internet, whatever that may be. Language like globally routable unicast IP address is the correct term and should not be suppressed, just because it is perceived as too technical. The article already explains private address, and in that context a public address is any that is not included there. I am inclined to revert the change and suggest something along the recommendation just given by Johnuniq. PS: The editor himself states that he doesn't know the correct term and apparently not the subject matter to decide on correct explanation, yet changes the article instead of asking for clarification. Kbrose (talk) 18:45, 5 April 2016 (UTC)

I'm confused.
Isn't there only 1 ipaddress, 127.0.0.1? Why are there more than one? Boorider7 (talk) 22:35, 6 April 2016 (UTC)

The Loop-Back Address 127.0.0.1 was just too useful to have only one address. When you author code that wants to "talk" to the localhost by IP value it is nice to have an IP value that is always correct for all systems. With more than one possible IP value for example 127.0.0.2 you can debug these requests and watch packets unique to your code use.

Numeric identifier
@Enthusiast01: Your edit (diff) suggests that an IP address is not a numeric identifier. That is incorrect—an IPv4 address is a 32-bit integer and an IPv6 address is a 128-bit integer. They are numbers, and are treated as numbers by host computers and routers. Humans see representations of these numbers in text form, but they are integers inside the computer, and are not simply "numeric" in the sense that the text I am typing is represented internally in a numeric encoding.
