Getting IPv6

From ClueWiki

There are a number of factors that determine how you can connect to IPv6. Use the descriptions below to help you choose a method. They are roughly listed in order of preference.

• If your ISP supports it, the best way of getting an IPv6 connection is directly through them. However, very few ISPs presently support native IPv6 connections. If you think your ISP might support native IPv6, contact them for more information on how to set it up.
• If your ISP does not natively support IPv6, the next best thing is to get a 6to4 tunnel. These add very little latency and are nearly as good as native support. To have a 6to4 tunnel, you will probably need a Linux or UNIX machine acting as your router with a global IPv4 address. See the 6to4 Tunnel Tutorial for more details.
• If for some reason 6to4 will not work for you, you can try to get an IPv6 tunnel through a tunnel broker. This usually requires some modifications to your router as well. Each broker normally has their own documentation on how to set up a tunnel with them. Tunnel brokers usually have more latency than a 6to4 tunnel because tunnel brokers have static endpoints. For a list of brokers, see the IPv6 Tunnel Brokers section.
• If you cannot use any of the above methods, Cluenet provides a service called ClueTun which allows you to tunnel an IPv6 connection over TCP. This normally does not require any modifications to your router. The downsides are that you only get a /80 subnet instead of the normal /64 or /48 with 6to4 or most brokers and that the latency is generally slightly increased from a tunnel broker because, like brokers, ClueTun has a static endpoint, and additionally it gets its own connectivity through 6to4. See the ClueTun Tutorial for more information.
