The 80% utilization rule makes sense for ADDITIONAL allocations, where an
end user already has space but needs more. Of course, exceptions can be
made for large deployments (customer has 150 hosts on a single /24, but
needs two more for a 400-host data center, etc.)
For initial allocations, the 50% rule makes the most sense, IMHO.
