A Closer Look at Google Public DNS

What role has Google played in the DNS ecosystem? Do you see them as a competitor or a partner?
Google has helped raise the importance of DNS above the network engineering community, which has been really good. They’ve also worked with us to advance the state of the art for DNS performance, something we’ve really enjoyed working with them to make happen. It’s not so much competition as it is choice in the market. If they started defaulting Chrome to use Google DNS, I think that’s something we would take issue with, but for now, we like the idea of people using a DNS other than their ISPs, that’s a good idea for a lot of reasons.
What are some of those reasons?
I like the idea of separation of services. ISPs provide a pipe. Other vendors provide security. Other vendors provide email. When one party controls all the services, it’s a “synergy” for the company, but rarely for the consumer. With DNS in particular, there are performance and security benefits that third party DNS providers offer that ISPs aren’t incentivized to do since DNS is a cost-center for them, and a profit-center for us.
*** and ***
I think anything which promotes heterogeneity on the Internet promotes stability. Diversity in services, service providers, and separating the layers of the networking stack are all important. Your ISP no longer provides you email because everyone either uses their own or has an account with Hotmail, Gmail or Yahoo mail. The same way people unbundled their email from their ISP, I think they should do with their DNS. Separation of services has been a long-standing best practice in the security community, and it applies now more than ever. In that vein, I’ll reiterate my view that I think Google controlling search, the browser, and the network or DNS layer is a dangerous trifecta that the consumer will probably be best served avoiding. I’m sure we’ll find out soon enough.

I’ve been a fan of separation of duties.
ISP EMAIL has always been a trap for their Customers. That “email@example.com” is the property of the ISP; not the Customer. Once you give that out to enough people you’re locked in.
Why not use a DNS service that has an incentive to be loyal to you?
Since finding OPENDNS, I have not had an DNS outages. I know that VERIZON, COMCAST, and GOOGLE have had outages.
Easy decision fmpov.
