More information in IEEE SA - Registration Authority page. The MAC Address Lookup is used to find the real manufacturer or vendor OUI (Organizationally Unique Identifier) of your network card based on your network card MAC address.
MA-S list constsis of SMALL assignments, a small assignment is a 36bit assignment where first four and a half bytes are assigned from IEEE and the last byte and a half are to be assgined by the vendor (i.e. MA-M list consists of MEDIUM assignments, a medium assignment is a 28bit assignment where first three and a half bytes are assigned from IEEE and the last two and a half bytes are to be assigned by the vendor (i.e. MA-L list consists of legacy and LARGE assignments, a large assignment is a 24bit assignment where first three bytes are assigned from IEEE and the last three bytes are to be assigned by the vendor (i.e.

Source of data is IEEE registry which is responsible for MAC address assignments and upkeeping of the registry. 01:23:45:67:89:AB), and three groups of four hexadecimal digits separated by dots (.) (e.g. Switches use this address to add to their lookup tables. Other conventions include six groups of two hexadecimal digits separated by colons (:) (e.g. The Source MAC Address field (6 bytes) identifies the frame's originating NIC or interface. The standard (IEEE 802) format for printing EUI-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens (-) (e.g. * source: wikipedia Notational conventions However, two NICs connected to two different networks can share the same MAC address. Network nodes with multiple network interfaces, such as routers and multilayer switches, must have a unique MAC address for each NIC in the same network. MAC addresses are formed according to the principles of two numbering spaces based on Extended Unique Identifiers (EUI) managed by the Institute of Electrical and Electronics Engineers (IEEE): EUI-48, which replaces the obsolete term MAC-48, and EUI-64. The address typically includes a manufacturer's organizationally unique identifier (OUI). Many network interfaces, however, support changing their MAC address. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address.Įach address can be stored in hardware, such as the card's read-only memory, or by a firmware mechanism. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer.Īs typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. The class can lookup a given Mac address on the given XML file and return the name of the vendor that produced the device that uses that Mac Address. It can take as parameter a XML file with the details of many known hardware vendors and the Mac address prefixes that they use to configure their network devices.

When you visit the page itll even tell you the device you are using This is our brand new free online tool for MAC vendor lookup. Our website tries to overcome these limitations.Ī media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This class can find the vendor of a device with given Mac address. Exciting news We have developed a new tool for MAC vendor lookup - to try to help you discover the device type of some MAC addresses on your network.
Martin Luther King, Jr.While there are a number of other MAC address lookup websites where one can lookup their MAC address most of them (at least the ones I looked at) have two major drawbacks 1st most look only at MA-L list from IEEE for lookups, which means not all MAC addresses can be identified and 2nd lookup by vendor is not possible.Lovett Elementary School Fine Arts Magnet.
