You do not necessarily have to stick to the old "class" boundaries. You can
choose to use only the 172.16.x.x/16 range and then sub divide it into
smaller or bigger parts for each network using variable length subnet masks
like the /20 /19 /22 etc which give you more hosts without restricting you to
the old class boundaries which is exactly what CIDR was meant to solve. (
CIDR= Classless InterDomain Routing)
