That's what we're trying to fix.

How big is "that big?" We have about 200 hosts total, but private
routes to 4 different customers. Without our legacy class C, we
would constantly be having to renumber in RFC1918 space.
We definitely could not qualify for PI under current rules.
We've already encountered collisions within RFC1918 due to trying to be
good net citizens and using RFC1918 for infrastucture, test networks,
VPNs, etc. Which is worse, having 100 people trying to renumber 20,000
hosts or 1 person having to renumber 200 hosts?
