It strikes me that it causes more headaches than it solves. the theory is that it means you have no route to send responses back to an attacker who uses tcp, i.e. a spammer. IANA-based data bogon filters are in fact mostly useful to filter attack issues using udp-based and similar protocols that don't require session establishment. the practice is that spammers use holes or super-blocks of allocated, i.e. not bogon, space. they are not stupid. It is still bogon space and completewhois bogon list catches most of those. Those that don't get caught are the ones where allocation exists but ip space is not being used (i.e. not advertised in bgp) and then doing super-block works for the spammer (there are ways to filter that as well actually but you ran risk of filtering those doing aggregation). And do remember that original question was about IPv6 allocation. Personally I don't know any spammers using ipv6 bogon space [yet]... so your point is well taken. randy

Re: IPv6 PI block is announced - update your filters 2620:0000::/23
Call me naive, but could somebody enlighten me as to what tangible benefit filtering out bogon space actually achieves? It strikes me that it causes more headaches than it solves. All packets arriving from bogon space have the evil bit set. There's nobody there you want to talk to, and there's nobody there that your users really want to talk to, even if they got the address from some legitimate source like the DNS server for examplebank.com. IPv6 bogons aren't likely to be spammers, because there's not enough critical mass there yet to make it worthwhile, but that just means that the greedy6 bit hasn't been implemented widely, and that'll eventually get fixed. -- Thanks; Bill Note that this isn't my regular email account - It's still experimental so far. And Google probably logs and indexes everything you send it.
