I don't see how this relates to IPv4-runout. The allocation (to AT&T) isn't all that new...and when they cancel this spammer, the space will undoubtedly be assigned to another customer.
And that other customer will find that it's poisoned space and will need to look for another subnet.
I don't buy that once IP space has been used by a spammer it's ruined forever. Only if abuse complaints are ignored for a considerable time are the IPs likely to end up widely privately blacklisted. Even then, I don't believe "space is widely blacklisted, please give us more" is a valid justification for going to ARIN for more IPs. We've terminated spammer customers...and reused their assignments. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
