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've heard of IPv6 before this week, but waiting for someone else to ensure I transition?

> 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 7 will hear RA and autoconfigure itself. Start here: http://www.ipsidixit.net/2010/02/24/228/ http://www.ipsidixit.net/2010/02/24/228/ You can get a tunnel here: http://tunnelbroker.net/main.php http://tunnelbroker.net/main.php Other people use this, but I prefer HE: http://www.sixxs.net/ http://www.sixxs.net/

  Or if you don't have static routable v4 address but have at least dynamically allocated v4 routable address you can use 6to4. I use this to configure my Debian-based router to change used v6 addresses to match DHCP-allocated v4: https://gist.github.com/806333 https://gist.github.com/806333 (bit of an ugly hack)

    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/ http://www.comcast6.net/ ).
    - danudey 16y ago
      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.
      - rbranson 16y ago
        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.
        dfox 16y ago
        Actually, /64 is the smallest indivisible network. You can divide that further, but then you lose this network/host identifier split and IPv6 features that require that (stateless autoconfiguration, privacy extensions...). So in case of normal network, ISP handing out /64 restricts topology of you network in that you can have only one network (with normal end-user devices). Using smaller networks than /64 is certainly possible, but it's not something you want to do on end-user network and it's best left only for things like point-to-point connections and intra-datacenter networks.
      - farktronix 16y ago
        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.

  As for fun exercises, you might want to try out the Hurricane Electric Free IPv6 Certification: http://ipv6.he.net/certification/ http://ipv6.he.net/certification/ It consists of a series of small and manageable tasks that will get you up to speed in no time.

All recent operating systems have very good support for it -- even Windows 7 will hear RA and autoconfigure itself. In fact, even Windows XP will automagically set up a 6to4 tunnel with no configuration needed if you have a public IPv4 address. Just enable IPv6 support for your connection and it does it all for you.

One of the frustrating things is when I talk to vendors about IPv6 and they say "oh, you're the only person to ever ask about that.." Just drop a quick line to any networks you do business with (home ISP, hosting provider, hosted DNS, etc...) and politely ask them what their IPv6 rollout timeline is. Their response will give you a lot of information about how on the ball they are in general.

First I would request it from my ISP. The more people requesting the more likely they are to take it seriously. The second thing I would do is setup ipv6. We are currently in a chicken/egg problem. No one uses ipv6 because no sites use it. No sites use it because no users use it. Adding a bit of ipv6 traffic to the internet helps. If your ISP doesn't offer ipv6 you can setup a tunnel using a ddwrt router and a tunnel provider like Hurricane Electric.
axod 16y ago
Nothing. Even if you host websites, nothing until ipv4 actually gets scarce or costly. Just because all ipv4 address space is "allocated" doesn't mean it's used or even allocated to end users. I'd start worrying when you have to pay a lot of money to get a second IP on a server for example. That'll probably be years away.... still good to read up on ipv6 though.
- xearl 16y ago
  Years away? Gosh! Depends a bit on where you want your servers to be located, I guess, but still. For a lot of server hosting customers, prices for additional IPs have already increased steadily over the last few months. But don't take my word for it, here's a bit from a recent APNIC announcement, for example: "APNIC expects normal allocations to continue for a further three to six months." (https://www.apnic.net/publications/news/2011/delegation https://www.apnic.net/publications/news/2011/delegation)

    For a lot of server hosting customers, prices for additional IPs have already increased steadily over the last few months That's just retail markup. If you peer with tier 1 transit providers you can still get IPv4 space for practically nothing.
    - dpifke 16y ago
      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.)
      - tastybites 16y ago
        Level 3 doesn't charge us either - what's really funny is some of the second-string ISP's actually pay you to take IP space from them.

I have been bugging my ISP (small, regional outfit) about IPV6 for the last 2 years, hoping to get them to move earlier than later. I called them again this morning, and they say that they still can't make a business case for it as they have 25% of their assigned IP space unallocated. They're waiting for some real momentum or need before committing resources to roll it out across their infrastructure. This attitude just adds to the chicken-and-egg problem, but I also know that this ISP is (human) resource constrained. They are constantly rolling out wireless solutions to unserved rural areas, so I must admit they are just being pragmatic. That said, as some other posters have suggested, getting a tunnel broker like HE and going through their IPV6 training game (Guru!) would be a great way to get yourself ready while your ISP figures things out on their end.
