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.
FastResolver doesn’t require any installation process or additional DLLs. Just put the executable file (FastResolver.exe) anywhere you like, and run it. After you run FastResolver utility, you can type multiple IP addresses and host names, separated by commas, spaces, or CRLF. Alternatively, you can select IP addresses range to resolve into host names.
