What Is an IP Address, and How Do I Find Mine?

Erik Emanuelli / September 9, 2018

An Internet Protocol (IP) address is a unique numerical address that identifies devices, like your computer, that can be connected to the internet or a local area network (LAN).

Knowing your IP address is extremely important to correctly configure networks, firewalls, or to identify who is on the other side of the screen.

IP addresses can be static (permanent) or dynamic (changing with every connection).

There’s also a difference between public IP addresses, which identify devices on the internet, and local IP addresses, which are assigned by routers to identify each device within a network.

How to find your public IP address

To find your public IP address (either static or dynamic), type “what is my IP” into a search engine and your address will appear.

To get additional insight, you can use a web service like Whatismyipaddress.com or Whatismyip.com to uncover information like the internet service provider to which it belongs, and even the geographical location of its user.

How to find your local IP address

If you’re using a Windows PC:

  • In the Start menu, type “cmd” into the search bar and press the Enter key on your keyboard to access the Command Prompt.
  • In the window that opens, type “ipconfig” and then press the Enter key.
  • Once done, you will see the information on your system’s network. The IP address of your computer is displayed next to the IPv4 Address, for example “192.168.1.10”.

If you’re using MacOS:

  • Open the Launchpad and select System Preferences.
  • Once this window is displayed, click on the Network icon and select the connection you are using (for example Wi-Fi) from the left sidebar.
  • Your local IP address will be displayed alongside the name of the network you are connected to.
