Hi,
While I think #3 is important, it depends on your use of the end-block, and those entries can sometimes be cleaned up with some work. If the block is listed, that would certainly lower my buying price I am willing
to pay for the block. I did buy a block once in the ARIN region which showed up in IP geolocation databases as Russian (no idea why), but it took me quite a while to get it fixed.
Sincerely,

Subject: Purchasing IPv4 space - due diligence homework
All,
Side stepping a migration to IPv6 debate…. I’d like to hear advise from the group about performing due diligence research on an IPv4 block before purchasing it on the secondary market (on behalf of an end-user company). My research has
branched into two questions: a) What ‘checks’ should I perform?, and b) what results from those checks should cause us to walk away?
My current list is:
Anything else? Advise?
Thanks,
Matt
