Purchasing IPv4 space - due diligence homework

checks should cause us to walk away?
I think it also depends on your intended use. If you want a flawlessly
clean block you can use for anything, you'll spend more time and money than
if it just has to accommodate a particular use case.
Run a mail server? Better be clean as a whistle. Geolocation only
Eyeball source? Past mail abuse may not be an issue but past DOS source
could be and woe betide those who don't pay attention to where in the world
Maxmind thinks the block is located.
We, DNS or game servers? It almost doesn't matter. Unless past abuse was so
bad that folks straight-up black holed it in the network, users will be
able to connect to you.
It's also worth considering whether you can move non-sensitive services
from older known-clean addresses to the new blocks, freeing those older
addresses for use in the more challenging application.
