An IP address is required by any device that participates in a computer network that uses the Internet Protocol for communication. It describes where on the Internet your computer is located. The IP address is a number that is assigned to each device, such as a computer, a printer, etc.

The MAC addresses are assigned permanently to adapters and cannot be changed as they are a unique identification of the hardware interface of network. The network interface card is used to connect to the Ethernet network. Click on “View Status” next to your network adaptopĤ.Key difference: A Media Access Control address (MAC address) is a unique identifier assigned to a network interface card (NIC) by its manufacturer. Click on Internet Network tray icon and select “Network and Sharing Center”Ģ. In this moment, I’m using my WiFi network for the internet connection so I can say that my second physical address (MAC) corresponds to it because, as you can see, the other two adapters are disconnected.ġ. In my case I have 3 physical addresses, one for dial-up, one for Ethernet and the last one for my WiFi adapter (ignore those 2 disable entrance because they are virtual graphic cards). You’ll see a list of Physical Addresses, one for each network adapter installed on your computer. Click on Start and type cmd in the Start search field than press Enter To find out MAC address for your network card you have two different options.ġ. It may also be known as an Ethernet hardware address ( EHA), hardware address or physical address. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number and may be referred to as the burned-in address. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card’s read-only memory, or some other firmware mechanism. A Media Access Control address ( MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment.
