How to Find the IP Address of a Web Site

Each Web site on the Internet has at least one Internet Protocol (IP) address assigned to it. Knowing a Web site's IP address can be useful for in several situations:

  • to bypass website blocking tools
  • to block specific sites (such as when administering a home network)
  • to help narrow down the geographic location of a Web server

Finding these addresses can be complicated. They are not usually displayed in Web browsers.

Additionally, larger Web sites use a pool of IP addresses rather than just one, meaning that the address being used one day might change the next. Two people in different parts of the world will often obtain different IP addresses for the same site even if they use the same lookup methods.

Using Ping

The ping utility can be used to look up IP addresses of Web sites (and any other kind of running network device). Ping attempts to contact the site by name and will report back the IP address it finds along with other information about the connection. For example, to find the IP address of lifewire.com on a desktop computer, entering the command

ping lifewire.com

will return a result similar to the following that contains the IP address:

Pinging lifewire.com [​151.101.193.121] with 32 bytes of data: . . .

Both the Google Play and Apple App Store contain many apps that can also generate these same "pings" from a mobile device.

Note that many larger Web sites do not return connection information in response to ping commands (as a security measure), but the site IP address can usually still be obtained. The ping method will fail if the Web site is temporarily unreachable or if the computer used to perform the ping is not connected to the Internet.

Using The Internet WHOIS System

An alternative method to find Web site IP addresses relies on the Internet WHOIS system. WHOIS is a database that tracks registration information for Web sites including the owner and IP address.

To look up Web site IP addresses with WHOIS, simply visit one of the many public sites (like whois.net or networksolutions.com) that offer WHOIS database query services. Searching for a particular site name like about.com, for example, produces a result similar to the following:

Current Registrar: REGISTER.COM, INC.
IP Address: 207.241.148.80 (ARIN & RIPE IP search) . . .

In the WHOIS method, note that the IP addresses are stored statically in a database and thus do not require the Web site actually be online or reachable over the Internet.

Using IP Address Lists

Popular Web sites have their IP address information published and available through standard Web searches. Examples:
