試したこと

[root@srv1 named]# nslookup srv1
Server:		192.168.30.105
Address:	192.168.30.105#53

Name:	srv1.users.net
Address: 192.168.30.105

[root@srv1 named]# nslookup srv1.users.net
Server:		192.168.30.105
Address:	192.168.30.105#53

Name:	srv1.users.net
Address: 192.168.30.105

[root@srv1 named]# nslookup 192.168.30.105
** server can't find 105.30.168.192.in-addr.arpa: NXDOMAIN

nslookupコマンドでipを入力するとエラーが出ます。
