An Internet Protocol, or IP, address is a unique string of numbers that identifies each device connected to the Internet. On Mac computers, your computer's IP address is visible in System Preferences. The IP address can change, however, depending on what type of connection you have and whether the computer is hooked up directly to a modem.
Click on the "System Preferences" icon in the Dock, or click the Apple button, then select "System Preferences."
Click on the "Network" button. Select the type of connection you are using -- either "Airport" or "Ethernet" -- and click the "Advanced" button.
Click on the "TCP/IP" tab. The IP address appears in the line next to "IP Address."
Tips & Warnings
- Your IP address may change periodically if you are using Dynamic Host Configuration Protocol or if your Internet Service Provider uses dynamic IP addresses.
