RE: FW: Delegating reverse DNS to a customer
Thank you for everyone's help. I'm going to pursue this with ARIN, since that seems to be the right way to do things.

IN NS ns4.emns.com. I believe that that will delegate the /24 to those servers from your servers. The delegation could occur at the parent level, but you do not control the parent 250.63.in-addr.arpa zone. No, you can't do a sideways delegation like that. The correct solution, as stated elsewhere, is to get 251.250.63.in-addr.arpa delegated directly from ARIN to the customer. - Kevin ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Delegating reverse DNS to a customer
Guys, We're a smallish (but growing) ISP, and we've been asked by one of our customers to delegate reverse DNS for 63.250.251.0/24 to their DNS servers, ns1.emns.com - ns4.emns.com. Unfortunately, we've never had to delegate DNS to a customer before, and we're having problems getting it to work. We're running BIND 9.5.1 on Fedora. Can anyone give me an example of how this should be done in named.conf and the file 251.250.63.in-addr.arpa.zone? I'd appreciate it! -- Tim ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
FW: Delegating reverse DNS to a customer
Right now, I don't have a zone 250.63.in-addr.arpa (I only have the
individual zones for each class C, 224.250.63.in-addr.arpa,
225.250.63.in-addr.arpa, and so on). So I need to create the zone
250.63.in-addr.arpa? I want to make sure that won't break my other reverse DNS
zones...
Thanks for your help!

Hi Tim,
Give the following a try:
In your named.conf:
zone 250.63.in-addr.arpa IN {
type master;
file 250.63.in-addr.arpa.zone;
allow-update { none; };
};
In the reverse zonefile on your server:
250.63.in-addr.arpa.
251 IN NS ns1.emns.com.
IN NS ns4.emns.com.
In your customer's named.conf:
zone 251.250.63.in-addr.arpa IN {
type master;
file 251.250.63.in-addr.arpa.zone;
allow-update { none; };
};
In your customer's reverse zonefile:
251.250.63.in-addr.arpa:
2 IN PTR whateverhost.emns.com.
