Hello!

While discussing PTR records for mail servers in a Vamsoft ORF
newsgroup, the question came up about who can set up a PTR and where.
I had always been told that only the owner of the IP block could set
up the PTR record, i.e., the ISP has to do it.

That'scorrect. Or, they can delegate it to you, but the odds of them doing
that are slim to none.


This question came up:

"I wonder what happens if the ISP customer's authoritative Name
Servers publish a PTR record for their ISP-assigned IP address--

OK. Where would the customer be doing this?

both
in the cases that the ISP does and doesn't have a PTR in their own
Name Servers. Is there some mechanism that keeps the customer's PTRs
from being looked-up by the Internet?"

So according to everything I have read (mostly posts in here), the
ISP has to do it.

Yes, as per above.

The question is, why can't anyone do it on their
own DNS server, or on their DNS host such as GoDaddy, etc?

This somewhat begs the question :-)



Thank you!
