The MAC Address Scanner is a handy free tool that will quickly collect MAC addresses for all the PCs on your network.
This can come in useful for a range of network tools. Wake-on-LAN utilities typically require a MAC address before they'll allow you to wake up a particular computer, for instance, while some security packages may restrict access on the basis of MAC addresses. You can collect these manually, but it's tedious, particularly for large networks: using an automated tool like the MAC Address Scanner makes more sense.
The program doesn't require any great networking expertise. Launch it, and the MAC Address Scanner will detect your current networks (both workgroups and domains). Choose one from the left, launch the Enumeration Wizard, step through it accepting all the default settings, and that's just about it. Once you click Finish the program will begin to scan your network, looking for other computers and capturing their MAC address.
This can take a little while, as the MAC Address Scanner must work its way through every subnet, extracting addresses from network protocols if possible, or contacting PCs directly if not. You can just leave the program to do its work, though. And once its finished, the Export wizard will save your network details to XML or CSV for easy analysis elsewhere.
Build 1.3.1 brings this change:
-Microsoft Windows 8.1 and .NET Framework 4.5.1 are supported
It's not exactly lightweight - the installation folder is a surprisingly bulky 41MB - but EMCO MAC Address Scanner is still a handy tool which could save you a great deal of time, particularly if you're responsible for a large network
