CCGetMAC is based on Microsoft Netbios technology. If you want to seach a computer's ethernet mac address, you just need to know his computer name or computer ip. That's to say, CCGetMAC can resolve mac address from IP or computer name. Vice versa, you can find ip address from mac address. CCGetMAC also can be used to Wake On LAN. You can use it wake up any computer on your LAN remotely.
