Hi all

If I do a "dig mydomain.co.za" from a Linux server, how do I know which DNS nameserver returns the queries?

I seem to have a faulty DNS server, but can't see which one, so I want to find out which nameserver (if there's 4 - ns1.myserver, ns2.myserver, ns3.myserver & ns4.myserver) returns the queries?

Towards the end of the output there should be a ;; SERVER: line that will tell you.

But you should probably just force the query to go to each of your listed servers and figure out which one is bad that way:

dig @ns1.myserver query dig @ns2.myserver query etc
