DNS is ('Domain Name System'), the Internet's equivalent of the telephone directory. It is an essential part of the Internet and stores the names of computers and their addresses. Every time you use a browser to look at a web site, every time you send email, your computer is using DNS to look up information.
Google Public DNS, then, aims to replace your ISP's default DNS with a (hopefully) faster, safer, and more reliable alternative. Google Public DNS isn't the first freely available alternate DNS we've seen.[Via]
