The first six months of this year nearly 100 million addresses were
given out by the RIRs. (How many were returned I don't know.)
With some 1100 - 1200 million lying around the IANA storage facility
unused, this gives us some 5 years before we run out of _unused_
address space, if nothing changes. Even if there is significant
growth, it's virtually impossible for those billion+ addresses to run
out within 3 years.
Five years is a long time, you can upgrade a lot of load balancers in
such a period. You can upgrade a good number in three years, too.
