Net::DNS, recursive queries & root nameserversby JPaul (Hermit) |

JPaul has asked for the wisdom of the Perl Monks concerning the following question:
Greetings all, I have recently become enamoured with Net::DNS, and being able to send and process not only queries, but replies. I have been having good success up until this point, and what appears to me like it should work is, at present, refusing to do so.
I'm attempting to use Net::DNS to complete a step-by-step recursive DNS query, like a "real" DNS server. By this, I'm attempting to take an unknown address to a root nameserver, and then follow the tree of DNS servers down until I get an authoritative answer. Perhaps there is something about the DNS structure that I don't fully understand? The route I've taken was using A.ROOT-SERVERS.NET, A.GTLD-SERVERS.NET to NS1.ANDOVER.NET... Or 193.0.14.129, 192.5.6.30, 64.28.67.55.
My thanks in helping me to understand this, -- Alexander Widdlemouse undid his bellybutton and his bum dropped off --
