Talk:Black hole (networking)

The differences between a null route and a black hole
A black hole isn't quite the same as a null route. As shown in the article, a black hole can simply be caused by stealth ports. This means that the route and the destination exists. Just because a destination doesn't reply, doesn't mean that it doesn't exist. Edit: Furthermore, black hole routes can not be detected without monitoring for lost traffic, whereas null routes are typically removed from routing tables when none of it's component routes exist. —Preceding unsigned comment added by 203.220.149.101 (talk) 02:50, 23 June 2008 (UTC)
