DNS서버 설정에 문제가 있는 것 같아요.

juliod.net이라는 도메인을 등록하고
도메인 등록기관에는 ns1.juliod.net ns2.juliod.net을 등록하였습니다.

그리고 서버 설정을 다음과 같이 하였습니다.
## /etc/hosts

127.0.0.1               localhost.localdomain localhost
220.72.23.200           juliod.net            ns1

## /etc/named.conf

//
// named.conf for Red Hat caching-nameserver
//

        directory "/var/named";
        dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        /*

         * to talk to, you might need to uncomment the query-source

         // query-source address * port 53;
};

이렇게 설정하였는데 juliod.net은 아이피가 안물립니다.

ns1.juliod.net으로 웹브라우져에서 접속하면 아파치 루트가 보여지긴 하네요.

뭐가 잘못된 걸 까요?
