I'll reply below with //s. My point is still: most companies do not use RFC1918 correctly. Your point seemed to be that it is not a large enough allocation of IPs for an international enterprise of 80K souls. My rebuttal is: 16.5 million IPs isn't enough?

That's comical thanks. come back when you've done it.
//Ok.
Marshall is correct.
//Ok.
If you'd like to avoid constant renumbering you need a sparser
allocation model. You're still going to have collisions with your
suppliers and acquisitions and some applications (eg labs, factory
automation systems etc) have orders of magnitude large address space
requirements than the number of humans using them implies.
//You used the metric of 80K people. Now you say it is a bad metric when I reply using it. Your fault, you compound it--you don't provide a better one. What are we talking about then? 100 IPs per person--say each person has 10 PCs, 10 printers, 10 automated factory machines, 10 lab instruments, 49 servers and the soda machine on their network? 80,000*100==8 million IP addresses. That leaves you with 8.5 million.... And that includes 80,000 networked soda machines. I don't think you have that many soda machines. Even on 5 continents. Even with your growing Asian market, your suppliers, and the whole marketing team.
In practice indivudal sites might be assigned between a 22 and a 16 with
sites with exotic requirements having multiple assignments potentially
from different non-interconnected networks (but still with internal
uniqueness requirements).
//Err. Doing it wrong does not justify doing it wrong.
