How to find the Ethernet Hardware Address

The Ethernet Hardware Address is also referred to as:
- MAC Address (Media Access Control)
- Physical Address
- Hardware Address
- NIC Address

It consists of six sets of two-digit hexadecimal numbers. These are usually
separated by dashes or colons, but may be separated by spaces.

For example:

Also, there is a separate MAC address for your wired and wireless adapters. Make sure you are recording the appropriate address.

Here's how to find it:

1) Go to Start - Programs - Accessories - Command Prompt.
2) At the prompt type ipconfig /all
3) You'll see a number in the Physical Address field in the format of 00-00-00-00-00-00
4) It will look like this.

Macintosh OS 10.3 and above
1) In "System Preferences", select "Network".
2) On the pulldown menu, select your Airport or Ethernet adapter, depending on whether you want the wireless or wired address.
3) Click on the "Airport", "Ethernet", or the "Advanced" tab, look for the "Airport ID" or "Ethernet ID".
4) That's the number.

1) At the command prompt type: ifconfig
2) Look for something in the form: HWaddr 00:01:03:DE:9C:BA
