IP address Mac address

A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Everything attached to any computer network has a permanent MAC address that moves with the hardware no matter where it is connected.

IP address is the current interface address for your local system to the larger public internet. The IP address can be STATIC (permanently assigned) or DYNAMIC (changes every time you connect to the internet).

The alphabetic names are for humans. They are translated to the xxx.xxx.xxx.xxx format for the computers to use. When you type in the name of a website the name is looked up by your browser.

The MAC address is for hardware. The IP address is for communication on the internet.
