Hi all, I'm not sure whether that would be more appropriate for the dev list, but I guess this is relevant/of interest to the SpamAssassin project, and I don't know whether this has caught attention here yet.
John in his draft mentioned below is very right to point out that simply applying the IPv4-DNSxL paradigm to IPv6 has the potential to drain resources from DNS caches. Especially, a spammer may cause DNS caches to fill with "useless" data by enumerating /128s in a /64 interface, and thus causing a spam filter to start DNS queries for all those /128s. I'm not yet convinced that John's proposal of a B-tree search encoded in DNS TXT records is really a good choice (it adds a lot of complexity to a previously extremely simple protocol), but maybe it's the best approach given the requirements. It makes most sense to discuss the proposal on the ASRG list. However, SA will be a major user of this protocol, so likely some implementation ideas can be discussed here as well. Personally, I'm also open for other ideas or approaches that make it feasible to query reputation lists in an IPv6 world, be it over DNS or some other transport protocol. -- Matthias ---------- Forwarded message ---------- From: John R.
