Wow, what a lot of NANOG traffic about IPv6 readiness for SMTP!
Please explain my misunderstanding on the following:
1. IPv6 is a Routing Layer Protocol (with some associated helpers, like =
RA, ND, DHCP-PD, and the like).=20
2. SMTP is an Application Layer Protocol, supposedly independent of =
Routing and lower layers of the protocol stack. Various communities have =
added connection initiation requirements that sometimes impinge upon =
layer 3 by requiring name/address correlations in DNS and none of which =
depend directly on technical aspects of layer 3 addressing. [ignoring =
obsolescent MTA implementations]
3. Arguing about IPv6 in the context of requirements upon SMTP =
connections is playing that uncomfortable game with one=92s own combat =
boots. And not particularly productive.
I look forward to furthering my education.
