How to Check Your Mac's IP Address

By Sharon Harp

An IP, or Internet Protocol, address is a unique number assigned to your computer that allows it to connect to the Internet and be recognized by your ISP, or Internet Service Provider, and other machines on the Web. The IP address contains four numbers separated by periods -- for example, 72.239.160.192. It takes just a few clicks to find the IP address currently assigned to your Mac.

Step 1

Click the Apple logo in the upper left corner of the menu bar at the top of the screen.

Step 2

Click "System Preferences..."

Step 3

Click "Network" in the "Internet & Wireless" field. Your Mac's IP address is displayed under "Status."

Tips & Warnings

  • If the computer is part of a LAN, the IP address that shows is a private address (or internal). This IP address may be dynamic or static, depending on how your network is configured.
  • If the computer is connected directly to the modem, the IP address that shows will be your public IP address, the one the ISP has assigned to you.
  • You can check out your public IP (if you don't want to deal with your router) from several websites. Check out the Resources section for "What's My IP."
