Jul 15, 2008 · Why Does My Router Have Three Mac Addresses? - posted in Networking: I have the ubiquitous Linksys WRT54G router, and when I go into its configuration settings under "Status", I can choose either

All devices computer devices that can be linked to a network have a MAC address. A MAC address does not have anything to do with the device being an apple product but rather a MAC address is give Jan 21, 2011 · I'll admit this is a bit of a stretch, but it's worth mentioning: the more email you have the more important having a defragmented hard drive is, and the higher the potential impact of the disk speed. As I said above, many email programs use indexes to optimize their ability to access your email quickly. Mar 24, 2017 · The full term is Media Access Control address, MAC address for short. A MAC address is made up of a 12 digit hexadecimal code that looks like MM:MM:MM:SS:SS:SS. Each manufacturer has their own MM part of the address while the SS part identifies that specific device by type. There are also 48 bit MAC addresses for 64-bit computing. Jun 09, 2019 · No worries. MAC Addresses are NI (Network Interface) specific. Each Network Interface will have its own MAC Address. So a modern computer with support for Wired Network (LAN Interface) as well as other types of network connectivity like Wireless Network (WiFi) will obviously have multiple MAC Addresses, one for each Network interface. Dec 02, 2009 · I have never seen it in AD. But in DNS you can ask Windows to display the MAC addresses and print the file. Better, since you are using Spiceworks, you should be able to get the MAC addresses from a report of the network cards on devices. This will give you MAC addresses for all devices, not just the workstations. You got two network adapters, one for wired and one for wireless internet connection. Both show another physical address (=the mac address) because the mac address is kind of 'unique id' for the network card. In the whole world there is only 1 card with the mac address you found. (of course you can spoof these but that was not the question :))

We can find mac address (physical address) of a computer using the command ‘getmac‘. This can be used to get mac address for remote computers also. Below are few examples on how to use this command. It works on XP, Vista, Windows 7, Server 2003 and Server 2008 operating systems. Get mac addresses from CMD

The situation with MAC addresses owned by a switch is quite convoluted. An unmanaged (i.e. not configurable) switch does not need and does not have any own MAC addresses because it is never a source or a destination of an Ethernet frame. It simply relays frames between its ports without being their source or destination. May 18, 2010 · Don't worry about the MAC addresses. IT is a unique number hard coded into every network adapter in existance. Think of MAC addresses like a street address, it simply is what it is and you cannot MAC addresses of all NICs or onboard NIC devices manufactured by the same manufacturer always start with the same 3-bytes OUI numbers. For example, suppose the IEEE assigns an OUI “0000AA” to the xyz company. Now the xyz company will use the OUI number 0000AA as the first 24 bits to build MAC addresses for its NICs or onboard NICs devices.

Media Access Control (MAC) Address – MAC Addresses are unique 48-bits hardware number of a computer, which is embedded into network card (known as Network Interface Card) during the time of manufacturing. MAC Address is also known as Physical Address of a network device. In IEEE 802 standard, Data Link Layer is divided into two sublayers –
