Host File Manager is a simple application that allows you to modify your HOSTS file on all modern Windows® systems. When you type an address such as www.google.com into a browser or anything else that resolves names using DNS, the hosts file is checked before it goes out to the internet to look up the IP address on your ISP‘s DNS server. This is useful if you want to block malicious addresses, or even advertisement servers. It’s also good for internal routing if you do not have a DNS server, but still would like to resolve names to other machines that do not use NetBIOS.

Administrator privileges (Run as Admin) are required for this application to work properly. It needs read/write access to the C:\Windows\System32\drivers\etc\HOSTS file.
