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.
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. Use a local address, so if your network is 10.0.1.x, then use that number to ping. Start by pinging the device you want the MAC to address for: ping 192.168.86.45.
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. Here is one example of how to find a MAC address using an IP address. 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.
If you want to use a user account other than administrator, replace 'administrator' with the account you wish to use.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. NOTE :: type the command exactly like it appears above only replacing the remote-host part with the workstations name you're querying.
You will be prompted for the password for account administrator. Wmic /user:administrator /node:remote-host bios get serialnumber If VNC or remote desktop connection to the remote-host is not available, execute the following from the local-host to get the service tag of the remote-host. If no computer name is specified, a connection to WMI defaults to the local computer. WMI makes no distinction between local and remote access. Obtain Service Tag remotely with command line Wmic csproduct get vendor,name,identifyingnumber In the command prompt type the following and press Enter/Return. Obtain Service Tag locally with command line Administrative rights are not required to run this command.Ĭhoose either method depending on your circumstances. Go to Start > Run and type cmd to start your command prompt. Service tag can be harvested via WMI either locally or remotely.
