Hi Team,

A DNS Novice question (no access to my lab right now). 

With the Random source port applied to a recursive server, what would happen
when it timed out form the authority not responding? Does it use the same
source port for the retry? Does is use a new source port for the retry? 

I'm thinking this might be very OS/implementation based.
