안녕하세요.
제 개인서버에서 nslookup을 했을때의 반응입니다.
김정균님의 강좌에 보면 nslookup 확인시..
[root@bbwuoo named]# nslookup
    Default Server:  oops.org
    Address:  210.24.154.2
	
    > 210.24.154.2
    Server:  oops.org
    Address:  210.124.24.132
	
    Name:    oops.org
    Address:  210.24.154.2
이런식으로 나와야 한다고 합니다.
그런데 저는 아래와 같이 나옵니다.

[root@ns root]# nslookup
> foobar.com
Server:   100.110.120.130
Address:  100.110.120.130#53

Name:   foobar.com
Address: 100.110.120.130
> 100.110.120.130
Server:   100.110.120.130
Address:  100.110.120.130#53

130.120.110.100.in-addr.arpa   name = ns.foobar.com.

또 쿼리를 날렸을때..
[root@bbuwoo named]$ nslookup -sil                         
   
> set query=ns
> oops.org
Server:         10.0.0.1
Address:        10.0.0.1#53

Non-authoritative answer:
oops.org        nameserver = ns.oops.org.

Authoritative answers can be found from:
ns.oops.org     internet address = 210.24.154.2
이리 나와야 한다는데..

[root@ns root]# nslookup -sil
> set query=ns
> foobar.com
Server:   100.110.120.130
Address:  100.110.120.130#53

foobar.com nameserver = ns.foobar.com.
foobar.com nameserver = ns2.foobar.com.

여기까지만 나오고 끝입니다.
인버스 도메인 설정부분에서 잘못한듯 싶은데..
대체 무엇을 잘못했는지 모르겠습니다.

[root@ns root]# cat /etc/resolv.conf
search foobar.com
nameserver 100.110.120.130
nameserver 100.110.120.131
