Enter a MAC address or Vendor to look up.(i.e. 00:A0:BF or Motorola)
In computer networking a Media Access Control address (MAC address) or Ethernet Hardware Address (EHA), hardware address, adapter address or physical address is a quasi-unique identifier attached to most network adapters (NIC or Network Interface Card).
It is a number that serves as an identifier for a particular network adapter. Thus network cards (or built-in network adapters) in two different computers will have different MAC addresses, as would an Ethernet adapter and a wireless adapter in the same computer, and as would multiple network cards in a router. However, it is possible to change the MAC address on most of today's hardware, often referred to as MAC spoofing. layer 2 network protocols use one of three numbering spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64, which are designed to be globally unique. Not all communications protocols use MAC addresses, and not all protocols require globally unique identifiers. The IEEE claims trademarks on the names "EUI-48" and "EUI-64" ("EUI" stands for Extended Unique Identifier).
MAC addresses, unlike IP addresses and IPX addresses, are not divided into "host" and "network" portions. Therefore, a host cannot determine from the MAC address of another host whether that host is on the same layer 2 network segment as the sending host or a network segment functioning network.
The w3dt.net MAC Address database contains a complete list of all MAC Addresses assigned to hardware manufacturers to date. You can perform a search for a Vendor (Hardware Manufacturer), or Mac Address by the following:
Search by vendor. for example: "motorola" or "apple";
Search by MAC address. for example: "00:A0:BF" or "00A0BF"
To lookup MAC address "00:A0:BF:02:01:FC" enter first 6 characters ... "00:A0:BF"
The w3dt MAC Address Lookup tool is based off data from the iEEE, David Nedved - 2007 - 2013.
