If you do really want to try to cure 20+ years of bad ideas and document it, go for it. I'd speak against doing so in this draft, other than a possible reference if said RFC ever happens. One of the big problems with the whole v6 PTR discussion is that every time somone (including me) has asked "so how are we using them in v4", noone has anything like a definitive list of what we're doing now. That doesn't even touch whether or not said uses are actually good ideas. I think there is value in making recommendations now based on current operational reality and detailing tradeoffs and real customer support costs in doing PTRs in v6, which seems to be the goal of this draft. If this turns into an RFC and eventually becomes a quaint bit of history, we can retire it. ebersman> Folks trying limit spam will hopefully figure out something ebersman> that doesn't involve reputation by IPv6 addr, 'cause at 18 ebersman> quadrillion per /64, that won't scale... vixie> ain't it great? a lot of servers are going to demand PTR's for vixie> V6. this will force the number of SMTP senders to be small. i vixie> don't love the mechanism, but i can't quibble with the social vixie> impact. So your grand scheme is to limit who can get v6 PTRs and that will be the new standard of whether or now you're tall enough to send email with the big boys? How's that worked out so far in v4 in the last few years? How about we admit that PTRs as a measure of trust and reputation is broken to begin with and won't scale or magically work better for v6 than v4? Let's come up with a better solution(s). _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
