Nit-picky technical correction:  the official standard on Internet names is 
STD0003, "Requirements for Internet Hosts".  This becomes important because 
there are multiple RFCs which say things about Internet names, and a couple 
of them allow other things -- e.g., RFC1033 states that underscores (_) are 
allowed in host names.  Since RFC1033 is not a standard, however, and 
STD0003 is, STD0003 takes precedence.
