Yeah, try https://tools.ietf.org/html/draft-ietf-dnsop-rfc2317bis instead :-)

Re: Allowable reverse mapping zone file names

[Lyle]

File names?   The file name is up to you.  How you reference it in your 
DNS server is something else.  That depends on your name server software.


As far as question 2, depends on if the reverse zones were delegated to 
you or not. It depends on your ISP.  Many do not delegate reverse lookup 
zones to the end user.  In that case, you have to ask them to insert the 
records you think necessary including your mail server's host name.

Two questions:

1. Where is the doc that completely describes the allowable reverse 
mapping zone file names?


2. When running my own authoritative name servers, do I need reverse 
mapping for anything other than my single mail server?


Thanks.

Best regards,

Thanks for the good advice, "/dev/robo."

Discuss that with your ISP or netblock owner.

There is no limit within BIND on what you name a zone file.  I 
suspect you might be wondering about the names of in-addr.arpa. 
*zones* instead?

To use an example, 127.0.0.2, a resolver would request a PTR record 
named "2.0.0.127.in-addr.arpa".  That is the reversed octets of the 
dotted-quad IPv4 address with ".in-addr.arpa" appended.

A zone could exist at any of these names:
* 127.in-addr.arpa
* 0.127.in-addr.arpa
* 0.0.127.in-addr.arpa
* 2.0.0.127.in-addr.arpa

(See also RFC 2317 for "classless" reverse DNS delegation, but no,
DO NOT read that: I only mention it for completeness, as we have 
pedantic posters on this list ... myself included. ;) )

You only need an in-addr.arpa zone IF that zone has been delegated to 
your nameserver[s] by a netblock owner or by your RIR (such as RIPE 
for Europe, ARIN for North America, et c.)

If the zone has not been delegated to you, ^^ go back to the top and 
talk to your ISP or netblock owner.

If you're still confused, tell us what your IP address is and we 
might be able to tell you who to contact.

Allowable reverse mapping zone file names

[Tom Browder]

I do not control 3-octet networks but need reverse mapping for my mail
server.

Two questions:

1. Where is the doc that completely describes the allowable reverse mapping
zone file names?

2. When running my own authoritative name servers, do I need reverse
mapping for anything other than my single mail server?

Thanks.

Best regards,

-Tom
