Children of a domain are called subdomains of the parent." I'd note a couple of things: 1) DNS is only one part of what makes the Internet the Internet (though arguably rather important for all the web surfers who wouldn't know an IP address from a telephone number); 2) the DNS root is more virtual than anything else, there's no requirement for it being present at any given point in time. If it's a hierarchy it's unlike any other hierarchy I've ever encountered.
