thank you again, more clarification, if anyone can pls shed light ...
That happens anyway if the forwarder is not authoritative - that is, the forwarder will act as a caching proxy.
ok - so my lab.company.com is authoritative, so it should keep a copy of company.com's information then and be able to respond to queries even within the domain of company.com?
It's not really polite to send private IP reverse lookups to the public root servers, but I suppose millions of places do...
i'm sorry, but how do i configure (or any pointer pls?) so that I do not point to the public root servers? i just followed templates; whereas, the company.com DNS, I was not the one who configured it.
I think the issues I have encountered are less now.... My questions.
1. From my lab.company.com DNS server - do I need to update my /etc/resolv.conf file so that it shows:
search lab.company.com company.com nameserver 192.168.17.2 nameserver 10.100.1.24
2. With the above /etc/resolv.conf I can ping forward and backwards hosts, except - reverse lookup to host within company.com's domain still shows the root servers .. :(
3. Strangest and confusing, is performing nslookup FROM lab.company.com's DNS server :
a. responds to nslookup company.com: nslookup 192.168.17.1 Server: 127.0.0.1 Address: 127.0.0.1#53
1.17.168.192.in-addr.arpa name = qatest1.lab.maxiscale.com.
[root@myhost named]# nslookup maxiscale.com Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: Name: company.com Address: 10.100.1.24
BUT it can't find an answer for ITS OWN domain:
nslookup lab.company.com Server: 127.0.0.1 Address: 127.0.0.1#53
*** Can't find lab.company.com: No answer
.... I must be missing something in my /var/named configuration files? Please advise.
thanks in advance,
from my lab.company.com DNS server
1. ping/nslookup
