Along the same lines, I noticed that the worst Actor in recent memory (McColo - AS26780) stopped paying their bills to ARIN and their addresses have been returned to the pool. It's my opinion that a very select number of CIDR blocks (another example being the ones belonging to Cernel/InternetPath/Atrivo/etc, if it were ever fully extinguished) are, and forever will be, completely toxic and unusable to any legitimate enterprise. Arguments could be made that industry blacklists can and should be more flexible, but from the considerably more innocuous case in this thread, that is apparently not the modus operandi
Putting these addresses back into use does not mean that they have to be allocated to networks where they'll number mail servers. ARIN staff is doubtless aware of the history of these blocks and will presumably do their best to allocate them to networks that aren't intended to host mail servers. Regards, Leo
