[root@test ~]# host 192.168.1.6 host: '6.1.168.192.in-addr.arpa.' is not a legal name (unexpected end of input) [root@test ~]# nslookup 192.168.1.6 nslookup: '6.1.168.192.in-addr.arpa.' is not a legal name (unexpected end of input) On the main server in the local network: [root@mirror lists]# host 192.168.1.6 Host 6.1.168.192.in-addr.arpa not found: 3(NXDOMAIN) [root@mirror lists]# nslookup 192.168.1.6 Server: 158.152.1.58 Address: 158.152.1.58#53 ** server can't find 6.1.168.192.in-addr.arpa: NXDOMAIN So that does seem to rule out the address beiny anywhere in use on the local network, doesn't it?
