QuickSetDNS is a new tool that allows you to easily change the DNS servers that are used for your Internet connection. You can set the desired DNS servers from the user interface, by choosing from a list of DNS servers that you defined, or from command-line, without displaying any user interface.
This utility works on any version of Windows, starting from Windows 2000 and up to Windows 8. Both 32-bit and 64-bit systems are supported.
You can download QuickSetDNS from this Web page.
