네임서버 설정후 구동시킬때 에러

안녕하세요. 초보 리눅서^^; 입니다.
네임서버 구축을 해보려고 도메인도 사고 열심히 노력 중입니다.

먼저 구동을 시키기 위해 /etc/rc.d/init.d/named restart 를 하게되면..
named 를 정지함: rndc: connect failed: connection refused 라고 나오면서
정지 [실패], 시작 [실패]
라고 나옵니다.

massage를 보니까.. 다음과 같이 나오구요.
starting BIND 9.2.1 -u named
using 1 CPU
loading configuration from '/etc/named.conf'
/etc/named.conf:61: zone '46.234.203.in-addr.arpa': already exists <-- 무슨 의미인가요 ?
loading configuration: failure
exiting (due to fatal error)

참고로 강좌 보고 설정한 환경 설정 파일들 입니다.

이렇게 설정을 하였습니다.
여러 선배님들의 질문과 답변글도 읽어보고 강좌도 제본해서 수차례 읽고 하는데도
아직 엮부족입니다. 많은 도움 주시면 정말 감사하겠습니다.
좋은 하루 되세요 ^^/
