DIG tells you which server returned the results. Look for the SERVER

dig @ns1.myserver domainname.com
dig @ns2.myserver domainname.com
etc, etc.

query?

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?

Hi Ken
I thought dig would return it, but it doesn't.
Look at this:
dig hfserver1.hostfactor.co.za
; <<>> DiG 9.3.3rc2 <<>> hfserver1.hostfactor.co.za
;; global options: printcmd
;; Got answer:

I know I can dig @server - but I want to know which is the active server
that returns a result at the moment
