Enabling IPv6 in Linux

I wonder why all the kernel compiling stuff is describred; for most (all) current distro's, IPv6 is enabled out-of-the-box.

There's an easy check for this: check if the file /proc/net/if_inet6 exists. If so, just do 'modprobe ipv6' (as root) and you've reached the same as after completing the kernel compiling stuff in the article.

And if you want IPv6 connectivity to the outside world, go to and run the newest script. Even if you're behind Alcatel / Thomson NAT, that script will take care of it.

    Hello Sander,
    Thanks for your feedback. It is true that the latest releases of distros include support for ipv6. However the steps are illustrated & useful for readers not running the latest distro releases & to give readers info on how to enable ipv6 support on their machines themselves.
    As for ipv6 connectivity, it is true that you can download and run a certain script to do that. However, in a follow up article, I will explain how to get an ipv6 connectivity to the outside world using Freenet6, explaining all the steps to the users so they would have knowledge of what they are doing.
    Thanks again for your feedback and I hope you read the upcoming article on connecting Linux machines to the 6bone using the Freenet6 service.
    Best regards,

      I'd like to point out that Freenet6 (and 6bone) are deprecated and will eventually be removed.

      A better way may be to use the 6to4 anycast address, as described here:

        I appologize for late reply. I wanted to double check the infomation before I post my reply.

        As far as addressing:
        - 6bone uses 3ffe::/16
        - "IPv6 Internet" uses 2001::/16 (the allocation of addresses is done by regional registries to
        - 6bone is phasing out in 2006 (still a few years...)
        - Freenet6, at this moment, uses 3ffe:b00::/16. I contacted them and they intent to continue supporting freenet6. However, it seems that some "competitors" of Freenet6 are sending false
        messages using the "6bone phasing out" to say that Freenet6 is going south... The reality is that large corporations are still using 3ffe::

        For more info on this, I suggest to contact freenet6 directly.

        Thank you,
