getnameinfo 확인되지 않은 IP

Ubuntu에 게이트웨이를 설치했지만 nslookup을 사용하거나 프로그래밍 방식으로 getnameinfo nslookup을 사용하여 로컬 IP의 호스트 이름을 가져올 수 없습니다.

fuad@URLF:~$ nslookup 192.168.1.107
Server: 127.0.1.1
Address: 127.0.1.1#53


** server can't find 107.1.168.192.in-addr.arpa: NXDOMAIN

Nuclei를 이용한 DNS 구성은 다음과 같습니다.

nmcli device show|grep DNS
IP4.DNS[1]: 41.128.225.225

라우터를 DNS로 추가하기 위해 nuclei를 사용해 보았습니다.

nmcli connection edit type ethernet
set ipv4.DNS 192.168.1.1

저장하고 종료했지만 여전히 동일합니다.

nmcli의 모든 출력은 다음과 같습니다.
