YudaIsPregnantDoNotPanic

I was reading my web stats, and I see this:

yuda.is.pregnant.do.not.p-a-n-i-c.com   1   1   16.73 KB    02 Mar 2005 - 02:57

It's actually a host too! Nmap says:

PORT      STATE  SERVICE
21/tcp    open   ftp
22/tcp    open   ssh
25/tcp    closed smtp
80/tcp    open   http
5801/tcp  open   vnc-http-1
5901/tcp  open   vnc-1
10000/tcp open   snet-sensor-mgmt

Okay, so anything.p-a-n-i-c.com resolves to the same IP... but how the reverse DNS lookup for 66.252.14.67 resolves to p-a-n-i-c.com, not the above domain name. Still confused.
