Want to know IP address of Google.com or Cnn.com? or do you want to know the host name domain of a specific IP address? In either case free utility ‘FastResolver’ should be handy big time.

It 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.

FastResolver [link] does not require any installation process. Just put the executable file (FastResolver.exe) anywhere you like and run it.
