Thanks NANOG. For those interested, here is a summary list of due diligence
tasks for purchasing IPv4 on the secondary market:
1. Check out the seller (Google search). What is their story? Generally
avoid hosting companies because they may have more block/black list cleanup to
do.
2.

I cleaned two blocks last year with Spamhaus and others. Took me less than two
weeks and Spamhaus were the quickest of the bunch (we're talking about a full

A big +1 to checking Spamhaus, specifically their DROP and EDROP lists. These
two lists are what causes us most pain when acquiring IPv4 space as a lot of
providers put auto blocking in place based on these two which can be difficult
to get removed.
