Re: query an external nameserver doubt
Here is an example: There is a CNAME Record www.example.test.com CNAME ts.example.test2.com in the example.test.com zone, which my nameserver is not authoritive. My name server is authoritive for example.test2.com zone. I receive a A query for www.example.test.com. I send this query to external nameservers and discover the CNAME record target is in my zone. Is this possible?

If he wants to be able to send a query to find all of the DNS CNAME records that point to his server, there is no way of doing this, as any domain could conceivably contain such a CNAME record, and he would have to query every name server. -- Barry S.

query an external nameserver doubt
Hi all, Is it possible to send a query to a external nameserver that can be a CNAME for a record located in other nameserver zone where we are authoritive? Thanks in advance.
