The average Internet user ends up performing hundreds of DNS lookups each day, and some complex pages require multiple DNS lookups before they start loading.

You can read about the specific technical improvements we’ve made in our product documentation and get installation instructions from our product website.

In theory, you point your DNS entries in your computer to Google Public DNS and you see faster browsing experience.

Alternatives to Google DNS?

The most popular free DNS solution so far has been the OpenDNS project. It is free and efficient and has a lot of nice features. If it’s how are they making money, you may wonder. Whenever you can’t find a website, instead of showing site not found error, they show you a page with ads and they make money off of that.

OpenDNS has a few advantages over Google Public DNS. It has been time tested where Google DNS is more like experimental right now.

OpenDNS also gives you a way to manage your DNS configuration. For eg. you could use it at work to prevent access to certain sites (getting around blocked sites is the most popular post here, go figure) or you could use it at home to protect your kids from seeing sites you don’t want them to.

You don’t get that with Google Public DNS.
