Very easy. In the Internet the equivalent of phone numers, the DNS names are alleady portable - so you can easily switch ISP and keep your email address and URLs without renumbering.
Imagine you are a hosting provider with, say, 10000 sites (domains), 3000 of them is even not under your control. You have 10 servers to host them (i.e. you need 10 IPs).
Changing ISP is really easy?
To be a LIR and grab /20 if really need only /28?
With a /28 you won't appear far in the current IPv4 routing tables either. Most sites filter prefixes longer than 24. How do you currently use such a /28 as PI? Or did you become a LIR and got that /20, just like is possible now with IPv6?
As an exercise for the readers try to remember why there are filters on IPv4 /24 boundaries and the try to figure out why there are quite a number of people not wanting IPv6 PI to fill their IPv6 routing tables.
Greets, Jeroen
one might also ask why a RIB/FIB entry has more relevance for one size prefix instead of another. --bill
