Hi all!!!
When I use nslookup with debug mode,
I got a below message.
But I don't know meaning of "SERVFAIL".
And I don't know what is difference between "SERVFAIL" and "NXDOMAIN"
Could you explain about it?
Thank you!!!
$ nslookup -debug 12.21.2.1
Server: ns.dacom.co.kr
Address: 164.124.101.2

;; res_mkquery(0, 1.2.21.12.in-addr.arpa, 1, 12)
timeout (5 secs)
timeout (10 secs)
timeout (20 secs)

Got answer:
HEADER:
opcode = QUERY, id = 50951, rcode = SERVFAIL
header flags: response, want recursion, recursion avail.
questions = 1, answers = 0, authority records = 0, additional = 0
QUESTIONS:
1.2.21.12.in-addr.arpa, type = PTR, class = IN
------------
*** ns.dacom.co.kr can't find 12.21.2.1: Server failed
