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
The issue is probably that you need to delegate the 251.250.63.in-addr.arpa
to your client in the 250.63.in-addr.arpa zone.
If you load 251.250.63.in-addr.arpa to try and delegate it, your servers
will answer for it because they load it.
Think of it in the same mind of delegating a forward subdoma

Thanks for your interesting explanations.
I assumed that Bind (alone and regardless of other variables), I assumed it
has a limitation for a certain number of hits per hardware.
After reading your reply, now I understand that Bind can handle same load on
less hardware requi
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 yo
Since the CIDR block you have been allocated containing 63.250.251.0/24
is smaller than a /16, ARIN is delegating authority for the IN-ADDR.ARPA
zones for each of your /24's directly to your dns servers. In order for
your customer's dns servers to be authoritative for
251.250.63.IN-ADDR.ARPA, you'
