The last of the major IPv4 blocks will get allocated by Feburary.

RIRs should run out of blocks to allocate ISPs by the end of summer.

After that is only carrier grade nat. Brave new protocols like NAT444.

NAT behind NAT behind NAT on the ISP level. You won't be limited by bandwdith anymore... you'll be limited by the number of connections that your ISP routers can maintain in memory and how fast they can process it.

You can kiss bittorrent goodbye. AJAX will run like shit and fail regularly. RSS feeds will start failing.

Hope you get used to getting your email in batches.

after that is buying IP addresses from other companies who suddenly find that they don't really need all the addresses that they are using (because they have all their desktops behind firewalls instead of exposed directly to the Internet like they were in 'the good old days')

No kidding. One thing about the IPv4 exhaustion is that the allocations
are extremely sparse. There must be a huge number of class C
allocations to small businesses which ony use 10 or so unNATed addresses
each. The rational thing for the ISPs is to start squeezing all this
sponginess by providing such price breaks.

What is very unsettling about this situation is that it's a preview of
what will hit later this century with respect to fuel, and even more
ominously, water. So far, the "free" market hasn't handled it so well,
has it?

actually, I think the free market is handling things fairly well with IPv4 addresses. just not the way the IPv6 advocates wish they would handle it.

Straight ratio looks bad, yes,

but see RFC 3194.

UUCP will save us!

Now that would be awesome.

NAT444...NAT behind NAT behind NAT on the ISP level.

NAT444 is two levels of NAT, not three. Each digit refers to an addressing domain, not a translation layer. The translation layers are the invisible boundaries between the digits. In NAT444, all the addressing domains are IPv4, hence three "4"s.
