현재 학교 전산업무를 담당하고 있습니다. 저희 학교는 krnic에 
ns.****.es.kr로 등록이 되어 있는데 외부에서 ping ns.****.es.kr로 
하면 응답을 받을 수 있지만 www.****.es.kr로 하면 응답을 받을 수 
없었습니다. 
그래서 여러가지 글을 읽어보고 dns 설정을 하였습니다. 며칠동안 시간을 
투자하여 간신히 했다고 생각을 했는데 보니까 서버 자체에서는 
ping www.****.es.kr로 하면 응답이 있는데 다른 외부의 컴퓨터에서 하면 
여전히 응답이 없습니다. 
왜 그런 것일까요? 답변을 부탁드립니다. 
 아래에 파일 설정한 것을 올려드립니다.
