<DIV>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.

<DIV>I'm willing to bet there is no single set of 'actual working servers'.</DIV>
<DIV>And since they are recursive servers, there are no 'hidden master'</DIV>
<DIV>servers anywhere either.</DIV>
<DIV> </DIV>
<DIV>Just a happy bunch of servers with the same IPs :-)</DIV>
