This addressing depends on company conventions. The remaining 3 bytes give the physical address. This is known as the OUI or Organizationally Unique Identifier. This field helps to identify the company which manufactured the computer. The first three bytes represent the manufacturer identifier. The MAC addresses are 48 bits each, which means each address is 6 bytes. Heck, it even finds HP’s address, though not sure whether it’s current or not.MAC addresses are of two types, the universally administered addresses assigned by the manufacturer of the NIC and the locally administered addresses which are assigned to a computer device by the network administrator. Then take the first 3 octets, such as E8-39-35, and do a search against the downloaded vendor list. Invoke-WebRequest -Uri $url -OutFile $outfile The script below will download the vendor list and save it in your home directory. All you need is the official IEEE vendor list that you can download or call up from your PowerShell script. getmac /s computername /v /fo listĭigging deeper, do you know that based on the MAC addresses we collected we can actually identify their network vendors. Need a different output layout, try the switch /FO with the options of “Table”, “List”, or “CSV”. You get a much detailed output with the switch /V. You can also get a remote computer’s MAC addresses as well, with the switch /C. To get local network adapters’ MAC address, simply use the comlet getmac which also returns a list of network protocols associated with each address. There are many ways to get to know your local or remote computers’ MAC address but here let’s check to see how we can get this data from a PowerShell console. But when it comes to waking up an offline computer on the same network we do need to know it before doing it. It’s a network address on TCP/IP network that normally we don’t care about that much. MAC address, a media access control address, is a unique identifier assigned to network interfaces for communications on the physical network segment.
