You want IPv6. But your ISP doesn't offer it. So what do you do? You create a tunnel.

How to choose[edit]

It doesn't really matter as much who you get a IPv6 tunnel from compared to where.

Ideally you want to ping the tunnel brokers IPv6 tunnel point and find out how long it takes for a package to get back and forth; this delay will be added to every IPv6 packet - so you want it as small as possible. The closest tunnel broker (less ping to their POP) is generally the best choice.

IPv4 to IPv6 Tunnel Brokers[edit]

International tunnel brokers[edit]


    • gives /56 or /64

  • SixXS - Six Access (no new registration)
    • Major operation with Points of Presence in Belgium, Estonia, Finland, Germany, Ireland, Italy, Netherlands, Slovenia, Portugal and the United States of America.
    • Known to be a very stable service until you suddenly get your SixXS account closed for no apparent reason (which eventually happens if you host a subversive website, write something negative about SixXS, etc)
    • Reverse DNS works
    • Uses a "credit" system. Uptime is rewarded with credits. The credits can be used to "buy" subnets and other goodies.
    • Accept RIPE, ARIN, APNIC, LACNIC, AFRINIC and their own SIXXS handles.
    • SixXS are known to close tunnels for no reason, and also close tunnels used to host websites with legal, but politically incorrect information. SixXS seem to support fascism and are generally hostile towards free speech.
    • SixXS will reject tunnel requests and insist you get native IPv6 from your ISP - even when the ISP doesn't offer IPv6.
  • Hurricane Electric -
    • Gives you /48 and /64 prefixes.
    • Stable, fast, numerous points of presence around the world.
    • New Hurricane Electric tunnels are now IRC blocked until or unless you pass their IPv6 exam. This seems to be a way to herd people into taking their exam. The exam should be very easy for people who know what IRC is, so this should not be an issue (I aced it at my first attempt).
    • Highly recommended.
