Ok, sorry, let me re-phrase.
I want to know on my own server, which of my nameservers replied to the
query. In this example 184.108.40.206 is our ISP's upstream DNS server, which
configured in /etc/resolv.conf - so it should technically appear there.
But, let's say I query host1.myserver.co.za - and myserver.co.za is on
another server, and has ns1.myserver.co.za, ns2.myserver.co.za,
ns3myserver.co.za & ns4.myserver.co.za
So, as far as I know, any one of those can reply (round robbin DNS?),
would like to know which one replies for this particular dig. Is that
possible? I don't want to specify a server to query, I want to find out
which of the 4 returns the query. If it's a cached reply, does it mean I
won't see it?
At the end of your dig reply you will see the following..
;; Query time: 26 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Wed Jul 9 10:49:40 2008
;; MSG SIZE rcvd: 297
That tells you which server answered the query.
I think you have missed a reply on this topic
That's the ISP's DNS server you see there.
dig +trace domain is what I needed
