IPv6 Tunnel Brokers?

thedillybar asks: "I have noticed the appearance of many IPv6 Tunnel Brokers which allow anyone to sign-up and tunnel IPv6 over their current IPv4 connection. Hurricane Electric and BT Exact both offer tunnels here and here, respectively. For those of you using a tunnel like this, what do you think of their reliability and use as a development tool?"

    I've been using freenet6 for a bout a year now. I've never had any problems with it, and I get a /48 for free, so I've been able to experiment with IPv6 on various machines on my network (FreeBSD, Linux, Solaris, AIX, and XP).

    I haven't written any IPv6 apps yet -- still need to read/buy a good programming guide.

      Having used 6to4 anycast tunnels for years and SixXS tunnels for months, I have to agree that they are an excellent form of IPv6 connectivity.

      As far as IPv6 programming goes, there's really nothing to it, most of the trick is getaddrinfo. The excellent KAME summary should get you started.

    SixXS is an excellent IPv6 tunnel broker for people in the RIPE region.

    And remember, if you can't find a nearby tunnel broker you can always try the 6to4 anycast address for /48 tunnels 192.88.99.1 .

  3. 6to4 by Anonymous Coward · · Score: 3, Informative

    If you have a static IPv4 address (or don't mind your IPv6 address changing), you can use 6to4 to get a v6 address without using a tunnel broker. Try a ping or traceroute to 192.88.99.1 (the 6to4 anycast address) to check how much latency you'll have. Your v6 prefix will be 2002:aabb:ccdd::/48 (where aabb:ccdd is your IPv4 address a.b.c.d, in hex).
