[Web4lib] Name server lookups and root servers

[John Fitzgibbon]

Hi,

I had the idea that I would teach myself a little about DNS lookups by
going to a root server and finding the name servers for the top level
domain .ie. and then doing a name server lookup for galwaylibrary.ie on
one of these servers.

I went to the DOS prompt and typed

Nslookup
Server a.root-servers.net
Ls -d ie.

I receive a message

"Can't list domain ie. Query refused."

Are there restrictions on who can query a root server?
