I'm certain that wasn't the intent of 1918, from the "random" wording. > How much of 10/8 and 172.16/12 does an organization with ~80k employees, > on 5 continents, with hundreds of extranet connections to partners and > suppliers in addition to numerous aquistions and the occasional > subsidiary who also use 10/8 and 172.16/12 use? My network serves around 300 machines and employees, and uses 10.10/16, though very sparsely -- we do indeed subject one /24 per function. The *point* though, is that it's 10.*10*. Another client is using 10.55.storenumber with one /24 per store. Cheers, -- jra -- Jay R.
