One Year After World IPv6 Launch — Are We There Yet?

Only 1.27% of Google traffic comes from IPv6 and barely 12 percent of the Alexa Top 1000 sites are even accessible via IPv6. In general though, the Internet Society is pleased with the progress over the last year. '"The good news is that almost everywhere we look, IPv6 is increasing," Phil Roberts,technology program manager at the Internet Society said. "It seems to be me that it's now at the groundswell stage and it all looks like everything is up and to the right."'"

      Well, this is the problem.

And the vast majority of users don't know the first thing about how the internet works, so wouldn't know to shop around for a v6 connection anyway.

      Its basically a chicken & egg problem: The people who are going to have problems with the IPv4 address shortage are the server operators, who would want to roll out IPv6-only services. However, the server operators aren't going to be able to roll out v6-only services while the consumers don't have v6 connections. Similarly, until there are v6-only services there's little reason for end users to go to the effort of implementing ipv6 on their own networks.

      So the only way this problem is really going to get solved is for IPv6 connections to be rolled out relatively transparently for the users. This is all doable - the ISP can implement IPv6 on their networks so the users don't have to know to shop around for an ISP that does v6; the ISPs can start shipping out v6-capable routers to their new customers instead of continuing to ship IPv4-only routers. Unfortunately, it seems a lot of the ISPs are also not interested in investing in their infrastructure (they cite the face that their users aren't actively asking for it, which of course they aren't). My personal preference is to avoid ISPs that aren't implementing IPv6 infrastructure, because it seems incredibly short-sighted, but of course most people won't know anything about this.

      The great need on the consumer end has indeed not yet occurred, and probably won't for some time. On the ISP side too, most of the ISPs still have plenty of IPv4 addresses to go around, and can start reclaiming them off internal systems when they start feeling the pinch.

      On the datacentre side, things are a bit different though. The people who are going to feel the pinch are the people operating the servers - that is where running out of IP addresses is going to be a real problem that won't be solvable with NAT (in some cases you'll be able to use an ALG to reduce problems, in other cases you won't).

      On the consumer side, going forward the requirement for IPv6 will be twofold:
      1. Accessing services that are IPv6-only. This *will* happen simply by virtue of the server operators not having enough v4 addresses. We'll probably see "reduced services" on IPv4 with extra features available for IPv6 users. This is especially true where the services are only intended to serve the local area - for example, a recent analysis of Google's data showed that over 10% of users in switzerland have IPv6 access, whilst only 0.22% in the UK do. Given a naive linear extrapolation, we might say that at some point in the future switzerland could have 99% of users with IPv6 access whilst the UK has around 2%. This would mean launching an IPv6-only service aimed at the swiss would be viable (and probably common), but would be inaccessible to most people in the UK. Splitting the internet like that would certainly be a bad thing, and people feeling increasingly cut off from useful services is what will drive both the ISPs and the end users to implement IPv6.

    "Switch over to IPv6" is a concept that detractors have pulled out of thin air, as it bears no relationship to how IPv6 rollout was planned and expected. Adding the word "immediately" just makes the misconception worse.

    IPv6 was always intended to run alongside IPv4 for the foreseeable future, because old IPv4-only equipment will be around for decades until it rots and it will need to be reachable until it is replaced. So, please don't talk about needing to "switch over" to IPv6. Wherever you got that idea from, it's wrong. Talking about it is propagating an invalid concept, and calling the expectation "naive" is just knocking down a straw man.

    IPv6 service merely needs to be enabled (without touching IPv4) on an IPv6-capable dual stack home router, and ISPs who offer IPv6 provide routers with it already enabled so you just need to plug them in. (If it's an old router then you'll have to enter the new IPv6 address info that the ISP gives you of course.) Simple home systems don't even need user configuration for IPv6, because IPv6 router advertisements then handle everything. It's as simple as USB for the home user, totally plug'n'play, which IPv4 never was.

    And once enabled, IPv6 works totally happily and transparently alongside IPv4 in the home network and at the server end, so there are no "switch over" issues. IPv4 continues to work exactly as it did prior to enabling IPv6. Browsers in particular just use IPv6 by default on a site that has it, and IPv4 if not. It's completely seamless for the end user.

    The additional security of NAT is no addition if all is working correctly. The additional security of NAT is making if fail in a safe direction: If something is wrong, no connection will be possible.

      Bollox. Many IP connectivity installations have exactly 1 ingress/egress router. This simply does not pass any traffic between any interfaces unless a stateful inspection rule allows it to. This matter does not change for IPv4 or IPv6.

      Sure unplugging and replugging a cable can cause a device to be accessible on the Internet, but this is also true of IPv4 and your DMZ/public IP network (if so configured).

      The only thing that IPv6 adds is that many IPv6 default installs might allow such an incorrectly plugged device to obtain information about the default gateway and therefore become accessible. However if this is a security concern is indeed a problem to you, then you simply do not enable Router Advertisement feature or IPv6 DHCP on the DMZ/public IP network segment. Such devices on the DMZ/public IP network might/could hardwire their default gateway (much like you already do for IPv4) or you setup IPv6 DHCP which will authenticate via MAC address (or other mechanism). But I understand router advertisement enabled on a DMZ/public IP network might be a concern (just like IPv4 DHCP would be for the same scenario of IPv4). Just turn it off!

      This way any incorrectly plugged in device will not be able to obtain a default route and is therefore in accessible.

      Now you have your security blanket back.

      IPv6 does not make things worse in the way you describe, when you better understand the improved mechanism IPv6 bring and how to take command of the IPv6 network configuration to make it less prone to human error.

      We have not even talked about IPv6 privacy extensions to fuzz/randomize/rotate the public IPv6 address used by a specific device to prevent the MAC address from being a constant source for leaking

  51. The need for IPv6 by unixisc · · Score: 1

    What are we discussing here - businesses, or home users? For home users, yeah, the case is weak, depending on the usage. For business users, it's certainly not the case.

    If one has a business and uses IP phones, having unlimited routable addresses for each of them, no matter how many, is a godsend. Similarly, if that business has VPN connections for its employees and similar tie-ups w/ partners, again, IPv6 is invaluable: using site-local addresses, the organization can avoid situations akin to IPv4 where 2 orgs have the same 192.168 addresses for different networks. While in IPv4 it's a pain to set-up, in IPv6, due to site-local or site-unique addresses, it would be a breeze.

    Similarly, if the organization servers have multiple virtual machines running on them, each of them can have a separate, routable connection to the internet independent of the host box, and therefore not depend on the connection of the host box. Also, if the organization has different e-mail, web, file servers, each of them can have independent IP addresses that can be set up to be either publicly accessible, or have limited public distribution.

    In short, if a business thinks that it doesn't need IPv6, in a lot of cases, they may simply not know that they actually do.

    We're trying to deliver IPv6 for our customers, but some major ISPs still either cannot give us IPv6 service at all or if they can, they cannot deliver it over our existing circuits, so we have to bring in new fiber, buy additional network equipment to terminate it, etc.

    Web hosts and websites can't switch to IPv6 until all possible site visitors are on it, because simply you can't address an IPv6 website from an IPv4 address.

    So neither hosts nor sites will switch until all the users are on IPv6.

    Which won't happen because until all the sites/hosts ae on IPv6 there's no reason to spend the money.
