Looks like Stanford already did this with their block: http://en.wikipedia.org/wiki/List_of_assigned_/8_IP_address_... Its a pretty interesting list of companies that still hold onto these blocks.

I have to wonder what the DoD's Network Information Centre needs with 151 million IP addresses. Surely they could spare a few.

Random point about this (my current employer is a national lab):

In 2006, the OMB issued a requirement that new DoD/DoE/USG/etc IT spend ("to the maximum extent practicable") be IPv6-capable, and tasked NIST with developing a testing framework for determining compliance:

Mind you, we were also supposed to be running at least dual-stack by 2008. ;-) Anyway, as of the middle of last year, this came along:

http://www.cio.gov/Documents/IPv6MemoFINAL.pdf

Basically, we have to be IPv6-capable on external services by 2012, and be ready for it enterprise-wide (for anything that touches the Internet; offline farms, etc. are exempt) by 2014. I don't suspect many organizations are going to hit that, but that's the target, and we're taking it pretty seriously here.

Also, here's a random resource: a totally unofficial IPv6 survey:

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.

18 quintillion is much much bigger than you think. The peak estimated birth rate on Earth was 173 million in the 1990s. If 200 million people were born every year and we gave every person a /64 block, we could allocate addresses for the next 92 billion years . The sun will be long dead by the time we use up that address space.

That's what we all think right now. They'll be laughing at us in the future when every nanobot needs an IPv6 address.

No, really- 18 quintillion is a huge number.

92 billion years is a long time to imagine. Let's say we won't have a use for these addresses after the sun dies in approximately 5 billion years, so we're going to try to use them all up by giving every person 1,000 /64 blocks.

Wolfram Alpha gives the surface area of earth as 5e18 square centimeters. 2^64 is approximately 1.8e19. With a single /64 block you could put two nanobots in every square centimeter on earth. That's not really practical over the oceans, but whatever.

With 1000 /64 blocks, you could cover the earth with nanobots that take up only 0.05mm^2 of space each.

Pixels on the average computer display take up 0.055mm^2.

You could address a display that covered the surface of the entire earth with just 1000 /64 blocks, and you could make one of these display for every person born until our sun dies.

It's an astoundingly huge number.

> 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…

A lot of the mobile telcos are going to be using DS-Lite or NAT64. What does this mean? Well, NAT64 relies on modifying dns entries. So, take this as a reminder to NEVER EVER hardcode pubic-facing ip addresses if possible!

Always remember to shave your pubic-facing IP addresses.

Practically nothing? Are there tier-1 providers charging for IP space now? I can confirm that neither Level3 nor Global Crossing charge for IP allocations as of a month ago. (The whole "charging for IP addresses" racket always left a bad taste in my mouth, since it's a public resource for which ISPs aren't paying, other than the overhead of being expected to justify and account for the space they've been allocated.)

Cogent gave us /22 (1024 IPs) free of charge in December.

For those reading along: loaned not gave

Best tweet of the morning: "I came here to kick ass and assign IPv4 addresses. And I'm all out of IPv4 addresses."

Thanks, someone retweeted it and I didn't have the link handy.
