无需任何 DNS 服务器即可解析本地主机？

有没有办法在没有任何 DNS 服务器的情况下解析本地主机？

下面是我的配置

# 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/hosts我也在文件中添加了名称

::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

当我尝试进行 DNS 查找时，它根本无法解析：

# dig saravana69rhel83  AAAA

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6_9.4 <<>> saravana69rhel83  AAAA
;; global options: +cmd
;; connection timed out; no servers could be reached

[root@saravana69rhel83 ~]# ping saravana69rhel83 
ping: unknown host saravana69rhel83 
[root@saravana69rhel83 ~]# ping6 saravana69rhel83

您使用/etc/hosts正确，但nslookup忽略了主机文件。它执行 DNS 查找，而不是查找主机名在您配置的环境中如何解析。尝试ping使用主机名，因为它将包含主机文件。

看为什么我的 /etc/hosts 文件在...时没有被查询
