[dns-operations] Google Public DNS

Yes, its face is 8.8.8.8 or 8.8.4.4 while background working servers are recursors. It is also right that there authority.  I am  just confused that how you made sure that you got NOERROR from Dallas, Texas and Stockholm, Sweden. :-)
Best wishes!

I'm willing to bet there is no single set of 'actual working servers'.
And since they are recursive servers, there are no 'hidden master'
servers anywhere either.

Just a happy bunch of servers with the same IPs :-)

Carlos
