This exchange brings to mind several questions (and comments):
1. Should not RFC 1033 be considered =93Historic=94?
I note that iPv6 was only a faint longing and otherwise =
undefined at that time.
2. What is the real rdns business requirement for residential =
customers?
I have difficulty finding anything but SMTP servers needing rdns =
entries.
Practical end-to-end security should be independent of media and =
addressing.
3. Would this question be better posed on the =93mailop=94 mailing list =
(if SMTP service is the issue) or perhaps =
dns-operations@mail.dns-oarc.net?
=09
Since =93hasser css=94 did not explain his business requirement for =
rdns, it really difficult to provide advice.
