First off, I'm not certain if unallocated space in blocks less than a /8
is properly called bogon, so pardon my terminology if I'm incorrect.
We're seeing a decent chunk of spam coming from an unallocated block of
address space. We use CYMRU's great list of /8 bogon space to prevent
completely off the wall abuse, but the granularity stops at /8's.
Obviously, I've written the originating AS and its single upstream
provider (sadly without any response). I'm not looking for a one time
solution for this issue however -- I'd like to permanently block (and
kick) anyone who's using unallocated space illegitimately.
How have you dealt with this issue? Does anyone publish a more granular
listing of unallocated space? Does arin have this information somewhere
other than just probing any given ip via whois?
Thanks!
