A MAC address (or physical address, or hardware address) is a unique identifier that each network-enabled device possesses. A MAC address is much like a Social Security Number for each device. If a device has both Wifi and ethernet (i.e. both wireless and wired connection) capabilities, it will possess a different MAC address for each connection type.
MAC addresses consist of 12 hexadecimal characters (the letters A through F and numbers 0 through 9).
Examples:
- 01:23:45:AB:CD:EF
- 01-23-45-AB-CD-EF
- 012345ABCDEF
Due to the wide range of different devices, a simple web search of your device model should provide plenty of helpful sites on how to find the MAC address of said device, e.g. "How to find MAC address on HP LaserJet 4250". It is generally advisable to ignore the search results that say "Ad" next to them and skip down to results obtained from the official website of your device's manufacturer, e.g. "HP".
The first few results should be enough to locate the MAC address of a device.
