OTOH, a spammer with a single /64, pretty much the absolute minimum IPv6 block, has more than 18 quintillion addresses and there�s not a computer on the planet with enough memory (or probably not even enough disk space) to store that block list. Sometimes scale is everything. host-based reputation lists scale easily to 3.2 billion host addresses. IPv6, not so easily.
Quite right. If I were a spammer or an ESP who wanted to listwash, I could easily use a different IP addres for every single message I sent. R's, John
