Thanks for the reply.
Another question followed: which DNS is under test?
I am configuring my DNS at 220.127.116.11 (google public dns), but the
analysis result indicates that "Your NAT has a built in DNS proxy. The
DNS request was received from 18.104.22.168". So the DNS performance
in done between my NAT box and the outside internet?
And when i am accessing the web, i checked that the DNS response is
actually received from the 22.214.171.124.
Thanks for the help.
