Use this tool to find the hostname, or domain name, of an IP address.

What is IP address hostname lookup?

The IP address hostname lookup tool allows users to find an IP address’ associated hostname. The hostname is the web address or domain name. The tool works with both IPv4 and IPv6 addresses, so users can search any address and the tool will return the associated hostname.

Why you should identify 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, meaning they would search for an IP address rather than a website name, but this is rarely done. Hostnames are far easier to remember and enter into search. If users look up hostnames by IP addresses, they can use those hostnames in the future, streamlining their Internet experience.

Hostnames allow for services in one host’s name to be provided to many servers and IP addresses. On the other hand, one server with one IP address is capable of providing services for many local hosts.

Finding the IP address and hostname in Windows or Mac

If you have a hostname or domain but want to find an IP address, you can use the DNS lookup tool linked below. Alternatively, to find your own IP address and hostname, you can use the functions on your computer, whether it be a Windows or a Mac.

To find your IP address or hostname in Windows, use the command prompt. Type ‘cmd’ into your Start menu to bring the command prompt up. Then, type ‘ipconfig/all’ and you’ll be able to see the hostname, DNS servers, default gateway, IP address, and more.

To find your IP address or hostname in MacOS, open System Preferences from the main menu. Select ‘Sharing,’ and you’ll find the hostname and IP address that your computer is operating under.
