due diligence research on an IPv4 block [...] what results from those
checks should cause us to walk away? Hi Matt, 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 moderately important. 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.
