wiki - Most popular misconceptions about networking

00000001 + 00000001 = 00000011 alt text http://locobox.googlepages.com/red_x_round.png





Time to fess-up!... 'at some point' you thought you knew something, and it ended up not being correct, or not entirely correct due to a misconception about the subject.




Let's build a good list of popular misconceptions novice AND even some seasoned IT administrators have, explicitly about Networking. My hope is to build a very useful brain-dump to serve as a good resource for the members of this community.






I'll start with an extremely obvious example (items with the most votes up will be on top):




  • All addresses beginning with 169 come from the APIPA failover system




    Only 169.254.0.0/16 is reserved for the APIPA assignation when the OS can't find an assigned address for a network interface (read:rfc3927).







*****Not to be mistaken with "Mistakes made by sysadmins"
