![]() ![]() In any of the above scenarios, the MAC address printed on the box and the one on the sticker of the device is likely it's base MAC, which would be 11:22:33:44:55:66 in this case, even though it uses multiple MAC addresses. Taking in consideration the OSI model, MAC addressing works at a layer (layer 2) lower than IP addressing (layer 3) 1. So, MAC addresses are hardware addresses that uniquely identify a network adapter 1. Exactly how these are laid out and used are often device dependent and different manufacturers handle it in different ways. But, just as a quick explanation, the MAC address is a unique value associated with a network adapter 1. ![]() In the modern era where it is quite common to have established a dedicated network connection, many devices are connected with the help of LAN or. MAC is a layer 2 device and MAC address is a layer 2 address in the OSI reference model. So looking at the MAC table of the first router upstream for yours would see the WAN address ( 11:22:33:44:55:66 if using the above example) and all devices on any LAN port may see the same MAC address as well ( 11:22:33:44:55:68 for example). MAC address refers to a piece of hardware that will control how the data would be pushed out onto a network. Note that in most home routers, there are two MAC address, one for the WAN and one for the LAN. 2960-1show mac address-table Mac Address Table - Vlan Mac Address Type Ports - 1 00ld.70ab. If you where connected to the LAN connected to LAN3 and performed an ARP -a you would see your gateway's address is associated with MAC 11:22:33:44:55:70 whereas someone connected to LAN1 might see 11:22:33:44:55:68 as the gateway's MAC address. The ethernet hardware address (or MAC) is a 12 hexadecimal digit number that uniquely identifies a network interface (and usually a computer) on a given. There are multiple ways to find your MAC address, depending on the type of device. Incrementing the MAC is common actually quite common, many higher end routers are laid out like so: The address format is the same for all network adapters a set of hexadecimal digits. Each "interface" will have a unique MAC address, this is even more obvious in enterprise grade routers where each address of the router for each individual LAN will have a unique MAC address, sometimes dozens of MAC addresses for one device. ![]() The base or "primary" MAC address of most routers is the MAC address of the WAN interface, not the LAN that you see in your ARP command. ![]()
