Google Public DNS
Google Public DNS is a free DNS (Domain Name System) service, announced on 3 December 2009 and part of Google effort to make the web faster[1], unlike other public DNS services, Google don't do any redirection when the DNS server fail to resolve the address[2].
Services
Although not explicitly declared as beta, the service, still in the experimental phase, does not accommodate the customer with a SLA. It does not use a third party DNS management software such as BIND, and use their own implementation method, which partly supports IPv6, and complies with the DNS standards set forth by the IETF.[3]
Privacy Issues
