How To Find Your IP Address and MAC Address In Mac OS X

You should know your Mac’s IP address for two reasons: The first is that it is commonly needed for setting up printers and other devices on a network. Secondly, it helps you protect your computer against malware. There are different ways to find out your IP address on a Mac; we’ll be discussing 3 of them below. We’ll first how to find the internal IP address of your Mac, and then the external one. After that, we’ll discuss how to find your MAC address.

This is the most easiest way for those of you who are more technologically inclined i.e more used to commands:

1. Open up Terminal via the Spotlight or by navigating to “Applications -> Utilities”.

2. Once Terminal is open, type in the following command:

ifconfig | grep "inet " | grep -v 127.0.0.1

This command will remove the 127.0.0.1 address from the window, which is a feedback loop and should be ignored while finding an IP address.

3.  Your IP address will be located next to “inet”:

Your External IP Address is the one that is broadcast to the world instead of a local network. An external IP address is used to identify your computer on the internet and can be used to identify your Internet provider; so we’d recommend never giving this to anyone.

1. Open up your internet browser and navigate to google.com

2. Search for “ip address”.

3. The first result will show your external IP address.
