On January 31st, 2009, at Sun Microsystems, I gave a presentation on IPv6 and the Hurricane Electric (HE) Tunnelbroker. The speech was given during the SupperHappyDevHouse 30 event and you can download the presentation slides here. The event attracted a SuperHappyDevHouse attendance record of over 400 people.
IPv6 is soon to become a reality as IPv4 exhaustion is predicted for 2011. A Tunnelbroker allows an individual to get IPv6 connectivity by creating an IPv6 tunnel over an IPv4 network.
