Follow these steps to quickly find the Internet Protocol (IP) and Media Access Control (MAC) address of a computer running Microsoft Windows XP, Windows Vista, or Windows 7.

For other types of computers and network gadgets, see: How to Find Your IP Address

Difficulty: Easy
Time Required: seconds

Here's How:

  1. Click the Start menu button on the Windows taskbar.
  2. Click 'Run...' on this menu.
  3. Type 'cmd' in the text box that appears. A command prompt window launches on the desktop.
  4. In this command window, type 'ipconfig /all'. Details are shown for each of the computer's network adapters. Computers installed with VPN software or emulation software will possess one or more virtual adapters.
  5. The 'IP Address' field states the current IP address for that network adapter.
  6. The 'Physical Address' field states the MAC address for that adapter.

Tips:

  1. Take care to read the IP address from the correct adapter. Virtual adapters generally show a private address rather than an actual Internet address.
  2. Virtual adapters possess software-emulated MAC addresses and not the actual physical address of the network interface card.

What You Need

  • Microsoft Windows XP or newer version of the operating system
