[ NNSquad ] DNS, DNSSEC and Google's Public DNS Service


(Administrivia: Catching up on a number of more technical items
that have collected over the last week or so.)

DNS, DNSSEC and Google's Public DNS Service

http://j.mp/1dMnfSd  (Circle ID)

   "Since March 2013 we've seen the proportion of end users who use DNSSEC
    resolvers that perform DNSSEC validation rise from 3.3% to 8.1%, or a
    rise of some 4.7%.  Most, but not all of this rise, can be attributed
    to Google's Public DNS service, which is used exclusively by some 5.6%
    of all clients across the entire Internet. When Google turned on
    DNSSEC validation on their resolvers, the majority of these clients
    were then performing DNSSEC validation even though they had not
    changed any part of their local DNS configuration. Just over one half
    of all clients who are seen to be performing DNSSEC validation, use
    Google's Public DNS Servers.  However, that's not the total population
    of users who avail themselves of Google's DNS services. A further 3.7%
    of users also use Google's Public DNS service, but they use it in
    conjunction with other DNS resolvers. The most common case here is
    that the other DNS resolvers used by the client, or by the client's
    local DNS resolver, do not use DNSSEC validation, so the SERVFAIL
    response from the query to Google's service prompts additional DNS
    queries to be made to other configured DNS resolvers. A total of 9.4%
    of the clients we saw in this experiment made use of Google's Public
    DNS service in one way or another."

Very much worth reading.
