A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
What is MAC and IP address?
The primary use of a MAC address is to ensure the physical address of a given device/ computer. The IP address, on the other hand, defines a computer’s logical address. Operation. The MAC address primarily operates on the data link layer. The IP address primarily operates on the network layer.
Why do we need MAC address?
The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Computer operating systems and broadband routers support viewing and sometimes changing MAC addresses.
What is an example of a MAC address?
A MAC address is a 48-bit hexadecimal address. It’s usually six sets of two digits or characters, separated by colons. An example MAC address would be 00:00:5e:00:53:af.

What are types of MAC address?
There are two types of MAC addresses: static and dynamic.
What are the three types of MAC addresses?
There are three types of MAC addresses: Unicast, Multicast, and Broadcast. The way to identify which address type you are viewing is simply look at the first byte. A unicast address’s first byte will be even, like 02, 04, 06, etc. The first byte of a multicast address is odd, such as 01, 03, 05, etc.
Can a MAC address be changed?
A MAC address can also be called a Physical Address. Read my post on how to find your MAC address if you don’t know it. All MAC addresses are hard-coded into a network card and can never be changed.
Can someone see my MAC address?
Nobody can see your MAC address on the Internet. Only people on the same LAN as you can see your MAC address. (That sometimes includes people sharing WiFi with you.) People don’t necessarily have to share the WiFi, MAC addresses sent wireless are always visible, as long as in range of course.
