There is, and it pertains to the amount of address space an ISP needs to
reserve. If, say, NezeqInt has 10,000 adsl customers, it would need to
reserve 10,000 IPs (about 40 /24s). These need to be aquired (from RIPE
for example), and it costs !!!. Using healthy statistics, you can see that
maybe about 30% of those are connected all at once, so they would just
hold some 7000 of IPs for nothing. Thus, they can save money, and not
waste the fast depleting IPv4 address space.
