Which runs at Layer 3 (networking and routing).
The second half of a MAC address represents the serial numberĪssigned to the adapter by the manufacturer.Ĭontrast MAC addressing, which works at Layer 2, with IP addressing, These IDs are regulated by an Internet standardsīody. The first half of a MAC address contains the ID number of theĪdapter manufacturer. MAC addresses are usually written in one of these formats: A MAC algorithm acceptsĪs input a secret key and an arbitrary-length message to be authenticated,Ī MAC address is a 12-digit hexadecimal number (48 bits in long). That are assigned to all ports on a switch. Identify one another at the data link layer, by using the MAC addresses
In Layer 2, multiple devices on the same physical link can uniquely This channel may provide unicast, multicast, The MAC sublayer emulates a full-duplex logical communication channel The MAC sublayer acts as an interface between the logical linkĬontrol (LLC) Ethernet sublayer and Layer 1 (the physical layer). Several terminals or network nodes to communicate in a network. Provides addressing and channel access control mechanisms that enable In Layer 2 of a network, the Media Access Control (MAC) sublayer
This will be your MAC address.įinding MAC address from Network Connection SettingsĪnother finding MAC Address example in windows is to check the details of your network adapter in Windows operating system. To find out the physical address of the wired or wireless adapter, you need to scroll down and look for the values next to “Physical Address,”. Step 2) Type command prompt in a “search” box.
1 means LOCALLY ADMINISTERED, which is similar to LAN (Local Area Network) IP address.īelow is a step by step process on how to find MAC address in Windows: Finding the MAC address with the Command Prompt: 0 indicates globally unique (OUI ENFORCED) to identify manufacturers and vendors worldwide or globally.
