Cisco Chapter 8 summary

Subnetting IP networks
Cisco Networking Academy

Intro
Subnetting is splitting a network into 2 or more pieces

8.1 Subnetting an IPv4 Network
Subnetting can greatly help a network. Subnetting makes network traffic lower and improves efficiency. There are several ways to subnet it can be anything from device type to location. The splitting of networks can be anything that is logical.

8.2 Address Schemes
There is a lot of planning that goes into a network and subnets also IP addresses. A school could have 3 or 4 subnets within its network and ip addresses for each group of people at the school. The 3 goals of successfully planning a network is to 1.prevent duplication of address 2.monitor security and performance 3.provide and control access.

8.3 design consideration IPv6
The IPv6 global unicast address normally consists of a /48 global routing prefix, a 16 bit subnet ID, and a 64 bit interface ID.

Summary
This chapter is about subnetting. Subnetting can be done in different ways based on the needs of the network. When building a network one should give it room to expand. If the network needs 4 subnets you should borrow 3 bits to give it 4 extra subnets in case of expansion. The other thing to take into consideration when designing a network is the class which the ip address falls under.
