Description

FastResolver is a small utility that resolves multiple host names into IP addresses and vice versa. You can simply type the list of IP addresses or host name that you want to resolve, or alternatively, you can specify IP addresses range that you want to scan. For local network, FastResolver also allows you to get the MAC address of all IP addresses that you scan. FastResolver is a multithreaded application, so it can resolve dozens of addresses within a few seconds.

Resolve IP Addresses Back To Host Name: If this option is checked, and you resolve an host name to IP address, the IP Address is resolved back into a host name, and displayed in "Host Name" column. The original host name that you typed is displayed under "Original Name" column.
