I failed to mention we're seeing this from an unallocated /20 whose parent /8 is allocated to ARIN (and is partially in use)
What /20 would that be? If you're sure it's unallocated, and see nothing but spam from it, block it at your border. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
