错误

server can’t find 200.137.168.192.in-addr.arpa: NXDOMAIN

原因

1、未配置解析该IP的参数

[root@centos1905 named]# nslookup
> 192.168.137.
Server:		192.168.137.100
Address:	192.168.137.100#53

** server can't find 192.168.137: NXDOMAIN
> 192.168.137.200
** server can't find 200.137.168.192.in-addr.arpa: NXDOMAIN
> 192.168.137.100
100.137.168.192.in-addr.arpa	name = ns.test.com.
100.137.168.192.in-addr.arpa	name = www.test.com.
> exit

• 192.168.137.arpa中未配置解析该IP的参数

[root@centos1905 named]# vim 192.168.137.arpa
  1 $TTL 1D
  2 @       IN SOA  test.com.        root.test.com. (

  4                                         1D      ; refresh
  5                                         1H      ; retry

 11 100      PTR     www.test.com.#解析192.168.137.100
 12 150      PTR     bbs.test.com.#解析192.168.137.150

2、DNS冲突

[root@localhost slaves]# nslookup
> 192.168.137.100
** server can't find 100.137.168.192.in-addr.arpa: NXDOMAIN
> ^C[root@localhost slaves]# 
[root@localhost slaves]# nslookup
> www.test.com
Server:		192.168.137.1
Address:	192.168.137.1#53

Non-authoritative answer:
Name:	www.test.com
Address: 69.172.200.235
> exit

• DNS冲突：配置DNS后未修改系统原来的DNS地址

解决

• 在192.168.137.arpa中添加此参数
• 修改DNS
