I don't know how they progress through the IP space, but couldn't they simply solve this by doing it in a deterministic manner? At progress N they should easily be able to tell that A has been scanned. Iterating three times through the IP space all IPs that haven't answered should have gotten the connection attempts.

That might introduce the same overhead that maintaining state does in the first place. It sounds like they're sending out at least a million requests per second.
