Is Google Public DNS based on open source software, such as BIND?
No. Google Public DNS is Google's own implementation of the DNS standards.
Does Google Public DNS comply with the DNS standards set forth by the IETF?
Yes.
Are there plans to release Google Public DNS code as open source software?
At this time, there are no plans to open source Google Public DNS, but
we have detailed all the steps we have taken to increase speed,
security, and standards compliance.
