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 (188.8.131.52). 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 [126.96.36.199] with 32 bytes of data:

What could cause this? If DNS is in fact returning 184.108.40.206, 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.
