  My method was as follows:
	1.  Search for strings of the form name1 = name2
	    where at least one of the names contains a '.' and does not
	    begin with a '.'

	2.  Eliminate all name so constructed which do not end in a known
	    top level domain.

	3.  Build the pathalias map.

	4.  Sort, and accumulate the freqency of use of each of these
	    presumed internet gateways.  Eliminate all but the top 200
	    from my list.

	5.  Build the pathalias map again, and sort again.  Now start
	    checking, in order of frequency of use, as to whether they
	    have Internet addresses.  Stop when you have enough.

	    (The last step isn't as bad as it seems, since many names are
	     well known so don't need to be looked up).

  I finished up with almost 100 hosts.
