Probably wouldn't take too long to check what % are pingable, which would give you a lower bound.

I'm willing to bet it would ;)

By my calculations, you'd only need to spin up 50 or so amazon instances, and they could cover the entire IP space in a day doing 1k pings/second each.

That's pretty doable.

Thats still not an insignificant amount of time/effort. I'd love to see someone do this though!

I asked this question on a similar article that gained no traction here recently: what do I, as a regular user of the internet, hosting no domains, and with no real responsibility for any website technicals, need to do about this? (Or what can I do about this?) Do I need to request something from my ISP? Lobby them to see if they take it seriously? Or do I have little choice but to hang around, feeling smug because I…

> Do I need to request something from my ISP? Lobby them to see if they take it seriously? Yes, but it's less crucial for you. Ask for a timeline for IPv6, if you'd like, but don't expect much. You can also set up IPv6 for yourself or your home network via a tunnel (which is a pretty fun exercise), and get access to the IPv6-enabled Internet. All recent operating systems have very good support for it -- even Windows…

Comments like these make me wish HN had a save feature. Thanks, you just got bookmarked.

I strongly recommend this or 6RD. It's a very straightforward and easy way of getting into IPv6 before ISPs start offering IPv6, as comcast did recently ( http://www.comcast6.net/ ).

From the Comcast link: Each user has been delegated a /64 block of approximately 18,446,744,073,709,551,616 (18 quintillion) unique IPv6 addresses. This seems like a ridiculous number of addresses, until you realize that this basically allows for 18 quintillion users, each with 18 quintillion addresses, before we exhaust the IPv6 space.

I think /64 was the guideline for the smallest divisible network an ISP should hand out. It basically allows for a household or organization to grow indefinitely while assigning anything that can hook up to the network a real IP address, with little restrictions on topology and/or address allocation layout. No need to reuse the addresses either, just give the new device a new one.

EDIT: I forgot to add that it also allows network devices to use their 64-bit link layer (ethernet/MAC) address as a host identifier.

These guys have been mapping the IPv4 space via ping over time (since 2003) and have an interactive browsable map that also shows blocks marked for localhost/private networks/multicast, etc and which registrars control which regions. It is pretty neat. Most recent data is Nov 2010. Since then the 11 /8 blocks that show as free have been allocated.

I suspect some workaround for IPv4 depletion will be created so ISPs wont have to upgrade to IPv6.

NAT?

Most likely. My understanding is that some ISP's are already giving customers RFC 1918 private addresses and NAT'ing them out to the Internet.

IPv4 is only "depleted" in a very technical sense. The last free /8 was allocated to a regional authority. This does not mean no IPv4 addresses are available. The regional authorities (RIRs), the guys who actually allocate the addresses to user organizations, still have many, many blocks to allocate. The first RIR isn't expected to run out of ipv4 space until October. That's when the shit really hits the fan -- reque…

APNIC is expected to run out sooner than October. October is on the high end of predictions, with some predicting as early as May based on burn rate. Two different sources:

http://www.potaroo.net/tools/ipv4/rir.jpg (probability distribution per-month)

http://www.tndh.net/~tony/ietf/IPv4-rir-pools.jpg

The entire point of this exercise is to raise awareness. The IPv4 reserves are depleted, and the five regions are now chewing on the crumbs. Granted, this isn't shit hitting the fan -- however, preparations for shit hitting the fan must be on everybody's radar right now.

Huge changes to infrastructure, which honestly should have been completed years ago, do not happen overnight. That's why this is news.

Then you get your bill from your isp, $5 extra per device.

I can seriously see this happening.

I don't.

In the past you paid for the extra's because the ISP had to do extra work for it.

But if the ISP sets everything up so all users have enough from the start. Like a /48. You won't have to bother them.

As far as I know only for mobile.
