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.
In your zone
251.250.63.in-addr.arpa (If you do not have a zone, create it.)
place the following four NS records as delegation records:
@ IN NS ns1.emns.com.
IN NS ns2.emns.com.
IN NS ns3.emns.com.
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.
