The ip address 127.0.0.1 is invalid to ever appear on the internet. It's a 
loopack address and more or less means "myself" to a computer.

The packet in question has a source IP address of 127.0.0.1. This 
particular case looks like a repose from a broken webserver.

Sometimes setting the source to 127.0.0.1 is used to try to DoS a machine 
by confusing it into a loop with itself, but only very old implementations 
of IP stacks are vulnerable to this (well before 1995, probably circa 1992 
or so).
