Domain Whois Lookup Server Hostname & IP address

This tool shows the domain server's hostname and IP address.

Hostnames may be simple names consisting of a single word or phrase, or they may have appended the name of a Domain Name System (DNS) domain, separated from the host specific label by a period (dot). In the latter form, a hostname is also called a domain name. If the domain name is completely specified including a top-level domain of the Internet, the hostname is said to be a fully qualified domain name (FQDN). Hostnames that include DNS domains are often stored in the Domain Name System together with IP addresses of the host they represent for the purpose of mapping the hostname to an address, or the reverse process.

The term hostname will vary according to the naming system in question. For our purposes hostnames are human-readable domain names. Sometimes these hostnames are assigned to another hostname or an IP address. This program will attempt to find the true hostname and IP address.

Computers have always needed unique addresses to talk to each other. With the advent of the Internet, the requirements for enabling computers to communicate with each other on a network included the concept of the hostname. The hostname began as a simple string of alphanumeric characters (and possibly a hyphen) and has evolved to its current definition, where hostname means a Fully Qualified Domain Name (FQDN) that absolutely and uniquely identifies every computer hooked up to the Internet via the Domain Name Service (DNS) naming hierarchy.
