Host files on Windows allows you to map host names with IP addresses, so that when a host name is encountered the IP address is automatically allocated from the host file. Editing the host file is not an easy task as you need to first locate it on your PC (based on the version) and then open it on notepad and then edit it. HostMan is a freeware tool for Windows which allows you to easily edit the host files without having to do it manually by searching for the file.
