Hey guys, I was wondering how the list of root hints were actually used when the DNS server performs iterative queries.
Since it's a list that seems to be in alphabetical order, does it simple use a.root-servers.net. first until it is unavailable, and go down the list? That seems unlikely since that one root would receive disproportional load compared to the others. I am aware that most of the roots use anycasting, so multiple servers are behind each entry.
Maybe it's round-robin?
I suppose I can capture packets and see what is actually going on... I might do that if no one replies!
