Hi there,

I had some answer from nslookup's query on my machine (FreeBSD
4.11-STABLE) last evening. BTW, what is different between
"Non-authoritative answer" and "Authoritative answer"? 
Yes, I'm beginner about DNS.

Here is the example:

---> the example begins here <---
bh at draba:~> nslookup
Default Server:  setaria.izb.knu.ac.kr
Address:  155.230.165.20

> set type=NS
> 230.155.in-addr.arpa.
Server:  setaria.izb.knu.ac.kr
Address:  155.230.165.20

Non-authoritative answer:
230.155.in-addr.arpa    nameserver = ns.ce.knu.ac.kr
230.155.in-addr.arpa    nameserver = ns.knu.ac.kr
230.155.in-addr.arpa    nameserver = ns2.knu.ac.kr

Authoritative answers can be found from:
ns.ce.knu.ac.kr internet address = 155.230.29.7
ns.knu.ac.kr    internet address = 155.230.10.2
ns2.knu.ac.kr   internet address = 155.230.128.2
> 
---> the example ends here <---

Sincerely,

Byung-Hee
