IPv6 switch: Is your equipment ready?

Summary: Some firms say software and hardware compatibility is preventing their move to IPv6, a claim Ripe's IPv6 Working Group co-chairman Marco Hogewoning investigates

Many organisations are complaining that software and hardware compatibility is hampering their move to IPv6. Marco Hogewoning investigates the IPv6-readiness of some vendors' customer premises equipment, including routers and switches.

A recent IPv6 global study by the European Commission has revealed that, despite increasing awareness about IPv4 depletion, some organisations are still on the fence when it comes to adopting IPv6.

When asked about the barriers for IPv6 deployment, about 60 percent of those organisations that had requested an IPv6 allocation from one of the regional internet registries said the lack of IPv6 compatible hardware and software was hindering deployment.

As less than six percent of unallocated IPv4 addresses remains, is the lack of vendor support really standing in the way of global IPv6 adoption?

Testing method
The tests we ran are best described as consumer panel testing. We checked if a feature is present and tried to verify if the feature actually works. This approach is by no means foolproof, as subtle differences in your local set-up can dramatically change behaviour.

Our aim is to provide a useful guide, but we strongly advise you to verify that the devices work correctly in your own environment before making a final decision to buy. Most vendors are usually happy to organise a demonstration of their equipment. If you are looking to purchase equipment in retail, we also advise you to check the returns policy of the retailer.

Those working in IT may know the importance of IPv6, but that awareness must spread beyond the tech community, says Axel Pawlik

We consider customer premises equipment (CPE) or home gateway to be a device that can act as a gateway between the infrastructure of your local provider and your home network. Such devices usually come with a variety of interfaces and can either plug into your DSL or cable connection or can be placed behind a box supplied by the provider to introduce additional functionality such as NAT44 — that is, IPv4 to IPv6 network address translation, VoIP or Wi-Fi.

The IPv6 behaviour of such devices is described in Basic Requirements for IPv6 Customer Edge Routers by the Internet Engineering Task Force.

In contrast with IPv4, when using IPv6 you are likely to get one or more subnets assigned by your provider, which means there is no longer a need for NAT. Although this re-establishes the end-to-end model of the internet, it does mean that your hosts are exposed directly to the internet.

For added security most of the devices described here come with basic filtering capabilities, often referred to as a firewall. Recommendations on these filters are described in the document Recommended Simple Security Capabilities in Customer Premises Equipment for Providing Residential IPv6 Internet Service by the IETF.

We have done our best to make this list complete and continue refining and adding to it. If you find anything missing or the equipment you are using isn't listed, or if you have any other feedback, please contact us at labs@ripe.net.

  • Are IPv4 addresses just about to run out, again? I think I first heard that the end was nigh for IPv4 at least 15 years ago, if not more. Every year there is one of those scare stories, and I'm not suggesting this in one of them so keep calm, pushed out to an eager technology media which informs us that the sky is falling. Is IPv6 Chicken Little or Henny Penny?

  • Whether or not IPv4 addresses will run out soon, I have noticed that it often seems to be companies that either sell network switches or who "kindly" offer their services in setting up your "sure-to-be-too-complex-for-you-to-do-it-yourself" network of new IPv6 gear who bleat on and on about IPv6 not being taken seriously enough, or indeed deployed soon enough.
    The truth is that the new protocol is actually much more auto-configurable than version 4, so even those of us who are utter simpletons, i.e. have only got a few years worth of further and higher education under our belts, will be able to buy a new IPv6 Internet router and plug it in. How hard can it be? Even my old computer with the current flavour of Ubuntu running is already IPv6 capable.
    No doubt there will be money to be made, especially from people who run fossilite Windows computers with no IPv6 compatible protocols installed, but even so, I still fail to see why the people in the "know" (or should I say people in the IPv6 hardware industry) big up this issue so much. The cynic in me already knows it's as much about making money from mugs in the public at large as was the Armageddon that year 2000 Millennium Bug was supposed to be and turned out to not be.
