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. Other conventions include six groups of two hexadecimal digits separated by colons (:) (e.g. 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. ![]() 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. Yu Fly Mikly Way Science and Technology Co., Ltd.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. This library provides a rudimentary command line interface: $ mac_vendor_lookup 50-D3-7F-00-01-00 There is also an asynchronous interface available: from mac_vendor_lookup import AsyncMacLookup async def main (): mac = AsyncMacLookup () print ( await mac. update_vendors () # <- This can take a few seconds for the download and it will be stored in the new path def find_mac ( mac_address ): print ( mac. cache_path = "/relative/or/absolute/path/to/the/prefered/storage/location" mac = MacLookup () mac. from mac_vendor_lookup import MacLookup, BaseMacLookup BaseMacLookup. Location of: os.path.expanduser('~/.cache/mac-vendors.txt') to your prefered location. If a customĭirectory is required, then override the class variable cache_path of class BaseMacLookup(.) from it default The library stores and looks for the list of MAC prefixes in a group predefined defaults paths. lookup ( mac_address )) Vendor list custom location or path ![]() update_vendors () # <- This can take a few seconds for the download def find_mac ( mac_address ): print ( mac. If you need up-to-date information, you canĭownload a fresh copy of the list directly from IEEE with MacLookup.update_vendors or AsyncMacLookup.update_vendors: from mac_vendor_lookup import MacLookup mac = MacLookup () mac. The library contains a list of MAC prefixes obtained at build-time. VEB KOMBINAT ROBOTRON Update the vendor list ![]() Installation pip install mac-vendor-lookupīasic Usage from mac_vendor_lookup import MacLookup print ( MacLookup (). It has an asynchronous interface using Python 3's asyncio as well as a regular synchronous interfaceįor old-school usage. This library provides an easy way to get vendor information from a MAC address.
