Worth Reading: DNS Is Part of the TCP/IP Stack
Another great blog post by Russ White: DNS is part of the TCP/IP stack, get used to it.
You might also want to tell application developers hard-coding IP addresses or anyone else believing in using /etc/hosts files instead of DNS that those things stopped being sexy around 1980.
One thing that rang true to me from the post is the mention of the “it could take up to 24 hours for DNS information to propagate” complain that we have to keep hearing. Ever heard of fastflux and DGAs in botnets and malware?
