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....
