Not possible with most modern IRCD's since they check forward and reverse dns.
So for example if your address is:
1.2.3.4
and that resolves to:
1-2-3-4.dsl.verizon.net
the ircd make sure that:
1-2-3-4.dsl.verizon.net
resolves back to
1.2.3.4

it's a simple and elegant solution that basically stops spoofing of this nature, on IRC anyway....
Wrong. On your IRCd. Not on mine.

Do I want to run my drone army on your IRCd?
