In case Norm or Walt aren't sure, I'll tell you what happens with my server.
I am allowed 5 computers on the system. The master IP is something like xxxxxxxx29, and the others follow like -30, -31, -32,and -33. No matter which computer is being used, the IP fingerprint will come out as the -29.
Oh... I'm confused about what shill posting is also. Is it the use of an alias?
