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:		192.168.137.100Address:	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> 192.168.137.100100.137.168.192.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.

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.comServer:		192.168.137.1Address:	192.168.137.1#53Non-authoritative answer:Name:	www.test.comAddress: 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
