A MAC (Media Access Control) address is a unique identifier, similar to a serial number. Each network adapter in a device has a different MAC address. A MAC address is known by several names, including
|Wi-Fi address||hardware address||adapter address|
|physical address||Ethernet address||LAN address|
A MAC address consists of 6 pairs of characters, usually separated by a colon, dash or space. A character may have the value 0 to 9 or A to F (case does not matter). Do not confuse a zero with an O “oh” (not a valid character) or an 8 with a B (bee, which is a valid character). Below are example MAC addresses.
