You can find the hostname of any computer with a public IP address by passing the address to any Domain Name System (DNS) server. The process of finding the IP address is achieved by searching the DNS (Domain Name Servers) until a match on the domain name is found. This process is also known as DNS lookup, NSLOOKUP or (erroneously) IP lookup

The process of finding the host name (or domain name) from an IP address involves sending a message to the IP address and requesting the computer located at that IP address to return its name.
