I just stumbled across something I thought was interesting. All the .mil domain names used by the U.S. Military are served by one single root server. I thought that was a bit odd. I'm sure that one server is more than enough to handle the queries for all the .mil domains with no problem, but it doesn't seem very redundant or safe at all. Especially for something our military uses. There's something that could be beefed up a little bit. My other thought (which others may know) was that perhaps the military runs G.ROOT-SERVERS.NET and I'm just not aware of it. Maybe it's a policy to only run .mil on what they can control? Even still, I think it might be in their best interest to setup a few more.

Ummmm. The SOA MNAME field is always a single server. bastet[~]$ dig +short mil ns @g.root-servers.net PAC1.NIPR.mil. H.ROOT-SERVERS.NET. G.ROOT-SERVERS.NET. CON2.NIPR.mil. EUR2.NIPR.mil.
