For example, I want to find the host name for 1.2.3.4. I have tried "whois 1.2.3.4" and get the error "whois: 4.whois-servers.net: No address associated with hostname". If I try "whois 4.3.2.1.in-addr.arpa", I get the error "No match for "4.3.2.1.in-addr.arpa". If I try some of the various options like "whois -a 1.2.3.4" it will return the name of the organization that owns the block of IP addresses but not the specific hostname for the address. So how can I use the whois command to enter my IP address and have it return my domain name?
