Subject: [External] : Re: NS query on bind9
Named is very picky about returned SOA records in negative responses. If it
has followed/seen a delegation then the returned SOA record in the response
needs to be at or below that point.
I suspect that named has a cached NS RRset between e164
Named is very picky about returned SOA records in negative responses. If it
has followed/seen a delegation then the returned SOA record in the response
needs to be at or below that point.
I suspect that named has a cached NS RRset between e164.arpa and
4.0.4.5.2.4.1.4.2.0.2.4.e164.arpa which i
EDNS0 would be my first guess. It’s very hard to tell without debugging output
from `named`.
But let me rephrase my response: If this is for an experiment or a school
project I would be happy to help, but if the goal is to unleash yet another
incomplete DNS server implementation then I would be

Hello Sonal,
are those queries done on internal network only? If global public DNS
root is used, how did bind9 found it should contact your server? Is it
configured via forward zone?
Public zone uses DNSSEC and bind9 does validate by default. I think your
problem is too short authority zone of SO

DNS is hard. My recommendation would be to not write your own DNS server,
but use an existing implementation that could be extended. Perhaps if you
share your design goals, we could help you

We have built a response for NS query and sending it to bind9. But however
bind9 is rejecting and getting server fail error.
NAPTR and CNAME queries are working fine.
