top-level domain
     
         the last and most significant component of an
        internet fully qualified domain name, the part after the
        last ".".  for example, host wombat.doc.ic.ac.uk is in
        top-level domain "uk" for united kingdom.
     
        every other country has its own top-level domain, including
        ".us" for the u.s.a.  within the .us domain, there are
        subdomains for the fifty states, each generally with a name
        identical to the state's postal abbreviation.  these are
        rarely used however.  within the .uk domain, there is a .ac.uk
        subdomain for academic sites and a .co.uk domain for
        commercial ones.  other top-level domains may be divided up in
        similar ways.
     
        in the us and some other countries, the following top-level
        domains are used much more widely than the country code:
     
        	.com - commercial bodies
        	.edu - educational institutions
        	.gov - u. s. government
        	.mil - u. s. armed services
        	.net - network operators
        	.org - other organisations
     
        since the rapid commercialisation of the internet in the 1990s
        the ".com" domain has become particularly heavily populated
        with every company trying to register its company name as a
        subdomain of .com, e.g. "netscape.com" so as to make it easy
        for customers to guess or remember the url of the comany's
        home page.
     
        united nations entities use the domain names of the countries
        where they are located.  the un headquarters facility in new
        york city, for example, is un.org.
     
        several new top-level domains are about to be added oct
        1997:
        	.nom   - individual people
        	.rec   - recreational organisations
        	.firm  - businesses such as law, accounting, engineering
        	.store - commercial retail companies
        	.ent   - entertainment facilities and organisations
