## Topic Body

- `dig domain NS` 명령으로 일반 도메인부터 TLD 네임서버를 볼 수 있음   
- `dig kr NS` 는 되지만 `dig ch NS`는 아무런 값이 나오지 않음. 왜 그럴까 ?  
- dig 의 결과 값 중 `bbc.co.uk.      900 IN  NS  ddns1.bbc.com.`  
   - 여기서 IN 은 Internet을 의미함   
   - Chaosnet 이 CH 이기 때문에 `dig ch NS` 는 Chaosnet을 검색하는 것   
   - Chaosnet은 1970년대에 사용했던 로컬 네트워크 기술   
- 즉 스위스 도메인서버를 보려면 `dig ch. NS` 라고 입력 해야함   
- DNS 에는 IN 과 CH 외에 HS(Hesoid)도 있음. '여러분 이거 다 아시는거죠?'
