Colasoft MAC Scanner is a Windows program designed for scanning IP and MAC addresses. It can automatically detect all subnets according to the IP addresses configured on the multiple NICs of a machine and scan the MAC and IP addresses of defined subnets. You can choose a subnet from the Local Subnet combo box and click the Start button or F5 to execute the scan. The program will display the scan results on the list, including the IP address, MAC address, Host Name, and Manufacture. The scanned results can be exported as a TXT file for future reference.
