DNS를 설정하면 외부 DNS 서버 역할을 하게 됩니다. 모든 설정은 기본값이며 관리자는 /var/named/named.ca 아래에 있는 루트 힌트 파일을 사용하라고 말했습니다. 루트 영역은 /etc/named.conf 파일에 언급되어 있습니다.

이름 지정 서비스를 다시 시작했지만 도메인 시스템에 ping을 실행할 때 해결할 수 없습니다.

Google DNS 삭제 후

"127.0.0.1"과 "192.168.161.1"을 추가하고 네트워크 서비스를 다시 시작하면. google.com @localhost를 찾아보세요. 이런 답장을 줬어

dig google.com @localhost
