This exchange brings to mind several questions (and comments):
1. Should not RFC 1033 be considered “Historic”?
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 “mailop” mailing list (if SMTP service is the issue) or perhaps dns-operations at mail.dns-oarc.net?
Since “hasser css” did not explain his business requirement for rdns, it really difficult to provide advice.
