   How MAC address is used in a physical transfer?

   • The MAC address is used on the physical transfer. An ethernet adapter does not know anything about IP. So the ethernet adapter uses the MAC address to address the receiver of the data packet. If the ethernet adapter would know anything about IP then we have to upgrade all our firmware to switch to a new protocol (like IPv4 to IPV6).

   How do MAC addresses work?

   • MAC addresses work with the card in your device that lets it connect wirelessly to the internet, called a Network Interface Controller (NIC). MAC addresses are used to identify which device is which on your local network so that data gets sent to your computer and not your roommate's smartphone.

   Why do I need both IP addresses and MAC addresses?

   • Here’s why both IP addresses and MAC addresses are required: MAC Address (Data Link Layer – Layer 2): Used for local addressing within the same network segment. MAC addresses are hardware addresses associated with network interfaces and are used to deliver frames within the local network.

   What is MAC address example?

   • There are special MAC addresses, one for example is ff:ff:ff:ff:ff:ff, which is the broadcast address and addresses every network adapter in the network. How do IP addresses and MAC addresses work together? IP is a protocol that is used on a layer above ethernet. Another protocol for example would be IPX.

   What is a MAC address in a layer 2 network?

   • In a layer 2 network, for instance a common Ethernet network, there exists a collision domain, where all the equipment connected can receive all the frames (layer 2 unit data) from any endpoint. But nobody outside the network can receive these frames. MAC addresses are addresses in these domains.

   What is the difference between MAC address and IP address?

   • MAC address are addresses for layer 2 (link layer) in the ISO/OSI or TCP/IP models. IP addresses are from layer 3 (Network layer) in the same models. In a layer 2 network, for instance a common Ethernet network, there exists a collision domain, where all the equipment connected can receive all the frames (layer 2 unit data) from any endpoint.

   Mar 18, 2024 · In modern networking, we use MAC addresses in the second layer of the OSI model (particularly in the MAC sublayer) and the first layer of the TCP/IP model. Thus, we can say that we’ll work with MAC addresses in the layer immediately before the network layer, regardless of the adopted model.
