I assign /22s to ISPs. When they use them up I give them another /22.
Private companies that show a need for a /24 are assigned a /24.
Ah. here is the rub. When you ISP buddies come back, you should ask
them to return the origianal /22 for a /20. That way, the total size
of the routing system stays the same!
