What is IP address hostname lookup?

This IP address hostname lookup tool does exactly what the name implies: it looks up the hostname of the IP address that you enter. Whether you enter an IPv4 address or an IPv6 address, you'll be able to find the hostname from the IP, letting you know the domain of the site behind the IP address that you enter.

Purpose of identifying hostnames

Hostnames are used when a web client makes an HTTPS request to a host. A user could theoretically specify an IP address as a request. However, this is rarely done; hostnames are far easier to remember and enter into search. They are also sometimes referred to as domain names.

Hostnames allow for services in one host's name to be provided by many servers and different IP addresses. Furthermore, one server with one IP address can provide services for many hosts.

Finding the IP address and hostname in command prompt

If you have a hostname or domain but want to find an IP address, you can use one of the tools below. Alternatively, to find your own IP address and hostname, use the command prompt in Windows. Typing 'cmd' into your Start menu brings the command prompt up. Type 'ipconfig/all' and you'll be able to see the hostname, DNS servers, default gateway, IP address, and more.
