Hurricane Electric's IPv6 connectivity has grown dramatically this year. In July, the ISP peered with 480 IPv6 networks. Next week's announcement that Hurricane Electric peers with 600 IPv6 networks represents a 25% increase in four months.

"This rapid growth uniquely positions Hurricane Electric's network to be able to provide the best native IPv6 connectivity to our business partners in strategic locations all over the world," said Martin Levy, Hurricane Electric's Director of IPv6 Strategy in a statement.

Hurricane Electric's role in pushing IPv6 traffic is being noticed across the Internet. Arbor Networks said in a that Hurricane Electric's free tunnel broker introduced in April was one of the main reasons that global IPv6 traffic grew more than 1,400% from September 2008 to September 2009.

Craig Labovitz, chief scientist at Arbor Networks, wrote that the most important IPv6 traffic increase "came on April 21, 2009, with Hurricane Electric's turn up of a global anycast'ed Teredo relay service. Hurricane Electric enabled 14 Teredo relays in Seattle, Fremont, Los Angeles, Chicago, Dallas, Toronto, New York, Ashburn, Miami, London, Paris, Amsterdam, Frankfurt and Hong Kong."

Labovitz said that "by all accounts, Hurricane Electric's Teredo service significantly improved the IPv6 goodput for the average Internet end user overnight."
