정리 하자면,

/etc/에는       resolv.conf
                hosts
                host.conf
                named.conf
         
/var/named 에는 localhost.zone
                joon.rev
                joon.zone
                named.ca
                named.local
이렇게 존재 합니다.

위와 같이 설정하고,

#/etc/rc.d/init.d/named restart
이상없이 OK 사인을 받았습니다.

-------------------여기서 부터 질문입니다.-------------------

그런데,
#nslookup
>joon.com 을 수행하면

Server:         127.0.0.1  
Address:        127.0.0.1#53
                           
Name:   lunarhunter.com                    
Address: 211.125.10.5

이렇게 떨어집니다...

새로 설치 하기전에는
Server:         127.0.0.1       --> 211.125.10.5
Address:        127.0.0.1#53    --> 211.125.10.5#53
이었는데... 왜 그런걸까요?

그리고 혹시라도 제가 빠뜨린거나 문제가 있는것 있으면
수정 좀 부탁 드립니다.

급합니다. 꼭 좀 부탁 드리겠습니다.
