DNS 서버 없이 localhost를 확인하시나요?

DNS 서버 없이 localhost를 확인할 수 있는 방법이 있습니까?

아래는 내 구성입니다

# ifconfig
eth4      Link encap:Ethernet  HWaddr 00:50:56:9C:4D:2F
          inet6 addr: 2004:c0a8:5b01:1:250:56ff:fe9c:4d2f/64 Scope:Global
          inet6 addr: fe80::250:56ff:fe9c:4d2f/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:196832 errors:0 dropped:0 overruns:0 frame:0
          TX packets:12558 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:16362576 (15.6 MiB)  TX bytes:2467903 (2.3 MiB)

/etc/hosts파일에 이름도 추가했습니다

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
2004:c0a8:5b01:1:250:56ff:fe9c:4d2f  saravana69rhel83 
2004:c0a8:5b01:1:250:56ff:fe9c:4d2f         localhost localhost.localdomain localhost6 localhost6.localdomain6
::1  saravana69rhel83 

DNS 조회를 시도하면 전혀 해결되지 않습니다.

# dig saravana69rhel83  AAAA

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6_9.4 <<>> saravana69rhel83  AAAA
