I haven't ran a recursive DNS server internally in a long time (I'm 
running Dnsmasq, which is a proxy or relaying server), but I don't have 
any reason to believe that the results would be any different. Any 
recursive DNS service I try and query outside my LAN just results in a 
timeout if I use UDP. At some point I probably did try a manual query 
against a root server, though I suppose I could try that again. The 
query sent to a root server is only different by a few bits from the one 
sent to a recursive server.
