DNS Helper (formerly Google DNS Helper)

DNS Helper is a freeware Windows tool designed to allow you change DNS settings on the go.
Besides being able to back up your very own DNS configuration, the application also comprises the default settings for the most popular DNS providers on the Internet, with dedicated tools to enable them on the go.
The minimal main window adopted a tabbed layout, so you can juggle between free DNS services and custom settings, while a restore feature makes sure you can revert to your original profile.
DNS Helper supports Google DNS, OpenDNS, Comodo DNS, DNS Advantage, Cisco Settings and ScrubIT, offering the standard settings for each of these services.
The application also places an icon in the System Tray and it requires just a simple right-click to quickly switch to a free DNS service provider.
DNS Helper is indeed an effective tool and since everything’s so basic, it doesn’t slow down the computer at all. It’s important however to note that administrator privileges are needed to change DNS settings on Windows 7 workstations.
As a conclusion, DNS Helper is one of the fastest ways to jump from the standard DNS settings to a free DNS service provider configuration. Plus, it comprises the most popular DNS services on the Internet, while also offering backup and restore utilities to make sure you’re on the safe side all the time.
