Partial Spoofing of User's Addresses

[Dan Udey]

I should also point out one thing I've noticed in the past on various
IRC networks. If you have user at cable.host.com and mask to
user at spoof.host.com, that works fine. If you have user at 127.0.0.1 and
mask to user at 127.0.0.spoof, then some (most?) IRC clients will assume
this is a reverse-resolved host, and will set banmasks like
user@*.0.0.spoof (which, depending on your code, may or may not work).
Masking IP addresses as 127.0.0.000 (or 999, or whatever) will
generally overcome this problem.
