comment Why don't DNS root servers answer?
For the first time I tried to dig to a root-server from my home network (when I asked the question I was at university) and it works. Probably the university network's firewall blocks the direct queries to a root-server and permits queries only to the internal DNS server. Is it possible?

If I query an other root-server, it doesn't work. I've the same output. But if I query 8.8.8.8 (for example) I've the correct answer.

I checked and the root hints file was updated. Anyway I update it again just to be sure. In spite of everything, dig @b.root-servers.net www.ubuntu.com still doesn't work (and it doesn't work even if I use any other root-server).

comment Install and use BIND9 as forwarder - step by step
If I simply use, for example, dig www.amazon.com I obtain SERVFAIL. If I use dig @10.0.2.3 www.amazon.com I obtain the correct answer. If I use nslookup I obtain SERVFAIL.
