Sirs,

I would like to make a request for advice on one problem I faced with DNS.

I have to delegate one /26 and one /27 subnet  in one reverse zone.
In my reverse zone file, I put these;

; <<128-159>> /27
128-159    NS    udns1.ultradns.net.
128-159    NS    udns2.ultradns.net.
;
129 CNAME 129.128-159.137.166.203.in-addr.arpa.

When I run the queries;
1. I can resolve NS query for dummy domain
> set type=ns
> 128-159.137.166.203.in-addr.arpa.
Server:  localhost
Address:  127.0.0.1

Non-authoritative answer:
128-159.137.166.203.in-addr.arpa        nameserver = udns1.ultradns.net
128-159.137.166.203.in-addr.arpa        nameserver = udns2.ultradns.net

Authoritative answers can be found from:
udns1.ultradns.net      internet address = 204.69.234.1
udns2.ultradns.net      internet address = 204.74.101.1

2. But, I got error on NS query for individual IP
> set type=ns
> 129.137.166.203.in-addr.arpa.
Server:  localhost
Address:  127.0.0.1

*** localhost can't find 129.137.166.203.in-addr.arpa.: Server failed

> 129.128-159.137.166.203.in-addr.arpa.
Server:  localhost
Address:  127.0.0.1

*** localhost can't find 129.128-159.137.166.203.in-addr.arpa.: Server
failed



Please advise me on how to fix the problem ?
I am not sure I am having problem with CNAME or the config is already
working ?


Respects,
Mt
