Colasoft MAC Scanner allows you to scan your network and gather a list of MAC addresses, along with IP address, machine name and manufacturer information (if available). The program can automatically detect all subnets according to the IP addresses configured on multiple NICs of a machine. It will group all IP addresses according to MAC address if a MAC address is configured with multiple IP addresses. Colasoft MAC Scanner supports multi-threaded scanning and can export the result list to a text file.
