Re: standards for giving out blocks of IP addresses

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.
