You are absolutely correct, it looks as if the "host" command strips the 
dot (I get an answer), while the "dig" command sends a query to a root 
server for the name as a forward lookup and gets back a "NX-domain" 
(invalid domain name) response.

I still see no utility to this, there are no numeric TLDs and are 
unlikely to ever be any.
