You can tell the difference between a remote host with a broken rDNS record and a real internal loopback by doing netstat -n. You will see the raw IP with no rDNS lookup. Local loopback connections will have or as foreign address.

Local loopbacks are pretty common. For example, I have Skype installed, which establishes one TCP loopback connection from port 1085 to 1086 and another from port 1086 to 1085.
