You may recall from earlier that the first part of a MAC address - the OUI - indicates a device’s manufacturer or vendor. Since MAC addresses are used behind the scenes, you generally don’t need to pay a lot of attention to them, but here are three instances when being familiar with a device’s MAC address can be worthwhile.

In the case of network-enabled printers with built-in control panels (as most have these days), you can find the MAC address by visiting the unit’s Network menu or printing out a configuration page (check documentation re: how to do this). Finally look for either the “ Ethernet ID” or “ AirPort ID” (you may need to click an Advanced button to find them).įor other network devices like external adapters and other non-PC devices, the MAC address is generally displayed on a sticker at the back or bottom of the unit.
Select System Preferences from the dock, then select Network, and depending on whether you’re using a wired or wireless connection, click on either Ethernet or AirPort. (In XP, click Start, then Run, then type “ cmd” and hit Enter.) Then from the command prompt, type ipconfig /all and you’ll see the system’s MAC address listed next to “ Physical Address.”įinding the MAC address on a Mac (no relation) is trickier and varies slightly by operating system version. To run it in Windows Vista or Windows 7, click the Start button then type “ cmd” (no quotes) into the search box and hit Enter.

What’s My MAC Address?įinding the MAC address on a Windows PC is easy via the command-prompt utility called IPCONFIG. Just as DNS matches a Web site name to an IP address on the Internet, a technology called ARP (Address Resolution Protocol) matches an IP address to the corresponding MAC address of a specific device to which that IP address is currently assigned. Given that IP addresses can’t be permanently assigned to a device-after all, a particular address can belong to one computer today and another one tomorrow- MAC addresses allow communication between devices on a local network by making it possible to reliably distinguish one computer from another. While MAC addresses don’t have any real significance on the Internet, they’re used in a similar way on a local area network.
To understand how MAC addresses are used, first consider that when you type into your Web browser, it can’t get there until a DNS (Domain Name Service) server looks up the corresponding IP address for the Web site allowing a connection to take place.
Together, the two parts of the MAC address form an ID that’s unique to a particular device.

The last three pairs of digits are specific to the device and can be more or less considered a serial number of sorts. For example, a MAC address that begins with 00:1F:33 denotes a Netgear product. The first three pairs of digits in the MAC address are called the OUI (Organizational Unique Identifier), which identifies the company that manufactured or sold the device. (Hexadecimal digits can only include the numbers 0-9 and letters A-F.)
A MAC address takes the form of six pairs of hexadecimal digits, usually separated by colons or dashes, and will look something like this-01:1F:33:69:BC:14. While an IP address can potentially be assigned to any device, a MAC address is “burned in” to a given device from the factory.

What Is a MAC Address?Ī MAC address, sometimes referred to as a hardware address or physical address, is an ID code that’s assigned to a network adapter or any device with built-in networking capability (say, a printer). But there’s another type of network address called a MAC address that actually forms the foundation upon which IP address communication is built, at least where local area networks are concerned. When you think about networking, IP addresses are probably the first things that come to mind.
