SixXS IPv6 Tunnel Provider Is Shutting Down (sixxs.net)

yakatz writes: SixXS started providing IPv6 tunnels in 1999 to try to break the "chicken-and-egg" problem of IPv6 adoption. After 18 years, the service is shutting down. The cited reasons are:

1) growth has been stagnant
2) many ISPs offer IPv6
3) some ISPs have told customers that they don't need to provide IPv6 connectivity because the customer can just use a tunnel from SixXS

This last reason in particular made the SixXS team think they are doing more harm than good in the fight for native IPv6, so they will be shutting down on June 6.

    Not at all sure that any kind of tunnel is appropriate in this day and age, anyway.

    Hell, just push all your traffic through us! It's fine! All that unencrypted email and DNS lookup? Don't worry, we're just converting to IPv4 for you!

    My home router has every IPv6 option known to man, including all kinds of tunnel and DHCPv6 etc. kind of connectivity.

    My ISP supports none of them. The problem is not that I couldn't get on the IPv6 net. It's that my ISP has zero interest in helping me do so. Until that's fixed, it's pointless worrying about another way to get to the same sites/services as I already do.

  4. Just a bit of nostalgia by istartedi · · Score: 2

    Fond memories of using something like this, if not SixXS itself over 10 years ago. Our ISP didn't do v6, and we needed to test with it. Tunnel providers to the rescue! Now even my local ISP that everybody complains about provides v4 and v6. It's been in Windows for... how many versions now?

    I'd forgotten all about these tunnel providers. News of one shutting down and a trip down nostalgia lane seems appropriate. So long, and thank-you for providing something that we needed at the time.

  5. People don't care because ipv4 works for them by Anonymous Coward · · Score: 2, Informative

    Most people are not affected by ipv6 so they don't care. So do the established ISPs. Most established ISPs sit on a big ipv4 pool and it would cost them to upgrade their legacy infrastructure. Newer ISPs are more hurt by ipv4 drying up as they don't get big chunks of ipv4 addresses any more, and need to do carrier grade NAT and similar strategies. So there is some motivation by them to aid in ipv6 adoption. Also, they do everything from scratch so deploying dual stack is easier for them.

    However, as long as everything works^{tm} on ipv4 networks as well, nobody will switch. What we need is ipv6 only, mainstream, services, to force home user facing ISPs to support ipv6, and ipv6 only customers, to force website owners to support ipv6.

    Just take google, they could easily give bonus points in their search result for web sites that support both ipv4 and ipv6. This would motivate countless site owners to do a switch.

      Almost all mobile phone providers in the US are switching over. They never really offered full IPv4 in the first place, with their networks fully NATed. But they're introducing real, routable, IPv6.

      From personal experience, on T-Mobile if your device supports it, you can even use IPv6 only (that is, your device only gets an IPv6 address, not even a NAT'd IPv4.) If you try to access an IPv4 only site, T-Mobile's DNS provides a virtual IPv6 address that can be used to route outgoing TCP connections to that address via a proxy.

      Now, some people would be unhappy with that situation if, say, Comcast were to do the same thing. But I must admit, I suspect 99% of the population would never notice, and over time, the few that do would find, say, their employers scrambling to have IPv6 gateways etc so they can use normal VPNs (the gateways to office networks, not the proxies for bypassing Netflix nation blocks I mean), and other applications that require full two way communication.

      IPv6 is very nice. It really is a shame there's so much inertia.

    Finally a company thats not money hungry alone.

    Given that SixXS has been free-as-in-beer regarding their services (and free-as-in-speech regarding some of their client side code), it's hard for them to be money hungry.

  7. IPv6 tunneling by DrYak · · Score: 4, Informative

    i will admittedly say i have no idea what sixxs is

    SixXS was a free IPv6 tunneling service, so that people with only IPv4 provider can still get access to IPv6 addresses through a 3rd party.
    (But more reliably than 6in4 which is dependent on the dynamic IPv4 address, and relies on volunteer servers reached though anycast).

    The idea was to break the chicken-and-egg problem faced by IPv6 migration :
    - content provider don't care about moving to IPv6 because nobody is using it and most people are still on IPv4
    - and ISP not spending the effort to provide IPv6 to their clients, because there's no IPv6 content to justify the move.

    SixXS provided a 3rd party with a very reliable way to get onto IPv6, so at least the "there are no users" excuse isn't valid anymore.

    Now fast forward a decade and a half later and nowadays a lot of content providers *ARE* on IPv6 (e.g.: Google, most universities, etc.), but there are still ISP not providing IPv6 on their network (e.g.: using something like 6rd, which basically works like 6in4 but relies on official servers with fixed address that is owned and operated by the ISP),
    Instead of that ISPs let the users go use SixXS, for the users who want IPv6. So rely on a free 3rd party service, instead of putting the efforts themselves to enable IPv6 for their own users as they should be doing.

    So SixXS is shutting down to force ISPs to setup and listen to their users and provide IPv6, instead of deferring it to SixXS.

    its sad to see them go since it was a free service, providing a service for people without means.

    The thing is, SixXS was providing a service that should in theory be provided by the ISPs themselves, but some are too lazy to implement IPv6 even after almost 2 decades.

    (and it's not for people without means. Technically, it's for people who have the means to pay an ISP for a connection, but said ISP is damn shit lazy and doesn't care to provide something more modern than last century's IPv4)

      -you get a rebuild protocol that tried to fixed many shortcomings of ipv4. you get encryption (ipsec) build in, dropped all the obsolete ICMP packets and now ICMP is useful to control the traffic (so no more drop all ICMP as you will lose features)
      -you get million of address and enabled you to get public IPs for all your machines, even internal machines. so NAT is not needed anymore. Firewall is still needed, but your home router will mostly stop being a router+NAT+firewall and be router+firewall
      -As no NAT, direct connect and p2p is a lot easier, no need for strange hacks and third party servers to punching holes in the firewall
      -dhcp, manual ip assignment and similar are past, with ipv6 the setup for users is just plug and use, even without dhcpv6
