Yes that's right , so I pass this IP to host command . This will get you something like this: YOUR_IP.in-addr.arpa domain name pointer hostname.domainname. with awk I get the last column which is hostname.domainname

are you sure you do not have any aliases for host command? it seems that your command host has an alias to host -a
