Good point. I thought that there is not much use for a public IP for a printer, but I did not think about big address allocations.

But is there any convenience in this? Can't they just switch a private LAN infrastructure connected through NAT?

Haven't we been told that IPv4 will run out "next year" for the past couple of years? I mean, yeah, it's a legitimate concern and all, but if you keep crying wolf...

It was a best estimate at the time. Reclaiming unused/wasted IPv4 space has helped some but routers have probably had a bigger impact. 5 years ago most ISPs were working under the assumption that the average customer was going to need (at least) 2 IPv4 addresses. My guess is the economic meltdown probably slowed down the growth of the Internet worldwide as well. I haven't seen any firm numbers to back that up it though.

No - the estimates I've seen have always been 'the space will run out in a few years'.

Printing from off-site is easier with a public IP, I don't know how often that is necessary.

Check the "v4 Exhaustion" widget on the right. It currently reckons there are 228 days left. I wrote an article about it on the 28th of May this year, and on that date, the widget calculated there were 427 days left.

This statement stands for itself. I don't see where it is implied that locally assigned addresses deplete the global IP space. Are you sure you aren't misappropriating the "or globally" part?

I can't wait for the last IPv4 address to be handed out. There is going to be so much opportunity for profit here.

I already got 2^33 entire IPv4 spaces for free. I only need about 3 addresses and I have 36893488147419103232 of them. Not sure how you're going to monetize that ;)
