The current list of top level domains is (at the moment):

  .COM  -  Commercial organizations
  .EDU  -  Educational institutions
  .GOV  -  Government organizations
  .MIL  -  Military sites
  .NET  -  Network administration sites
  .ORG  -  Other random "organizations" that don't fit in any other domain

plus, the ISO country codes (like .UK, .AU, etc.) are top-level domains
for the associated countries.

The .ARPA domain is a temporary top-level domain for old ARPANET/MILNET
sites who haven't converted to the domain system yet.  There is no such
thing as the .UUCP domain (at least, as far as the root nameservers are
concerned);  it is a "fake" domain that some mailers happen to know how
to deal with.
