FastResolver is a small utility that resolves multiple host names into IP addresses and vice versa. Simply type the list of IP addresses or host name that you want to resolve, or alternatively, you can specify an IP address range that you want to scan. For local network queries, the program also allows you to get the MAC address of all IP addresses that you scan. FastResolver is a multi-threaded application, so it can resolve dozens of addresses within a few seconds. The list of resolved IP addresses can be exported to HTML report or copied to the clipboard in HOSTS file format.During our test, FastResolver processed over 400 IP addresses in a matter of seconds..., so yes, it is fast!
