DNS: same IP, 2 different domains, 2 different routes
Posted on 2006-05-16
I have a server with several websites on it. If I trace route any of those domains, I get the same path as when I trace the IP (220.127.116.11). Now if I trace mcguirksand.com, I get something totally different. The trace gets stuck in a loop at hop 19

Also when I ping mcguirksand.com I get this:
Pinging mcguirksand.com [184.108.40.206] with 32 bytes of data:
Reply from 220.127.116.11: TTL expired in transit.
What could cause this? If DNS is in fact returning 18.104.22.168, then the route from my network to the server should be the same no matter what domain I query to get the IP!?
I do not manage the DNS for this domain, so that limits testing options.
