When Google released their public DNS offering, there were two main reactions that followed:
1.Wow this is a FAST DNS resolver!
2. Oh… I don’t trust Google with this.
Question 1: City/Metro Data
Question 2: Temporary logs
Question 3: Modeling/Tokenization of data
At face value, one may interpret the FAQ and privacy information to think that the data may be used to populate a model or otherwise replaced with a token to replace real DNS traffic with an artificial representation of DNS traffic. Is anything like that used, or are any additional steps taken with the DNS data that are not listed in the FAQ and privacy pages (or other resources)?
Question 4: Financing/Funding
I realize that Google has money yet is in the business of making money. What is the internal cost justification for Google DNS and how would you explain its internal funding?
Question 5: TTL and Prefetching
Is Google DNS doing anything with TTL caching that may not be from the authoritative nameserver? This stems from one reader’s concern over the prefetching and possibly modifying the TTL values. Can you enlighten any more on the prefetching operations?
