I finally made the permanent switch to IPv6 connectivity. Over the past few years, I played around with it several times, but recently when the cable modem provider took away my pack of extra dynamic IPv4 addresses I decided the time was right to make the leap. It is amazing how much faster developing peer-to-peer applications is when you can assume that each side has a publicly-addressable IP address as you can with IPv6.
After looking around for a good list of IPv6-enabled sites (ie. I’ve got IPv6…what can i do with it?), it became apparent that such a list does not exist. The best is The “Official” 6bone Webserver List”, a boring white page, hosted on a an old webserver at a university in Germany. Hardly very Web 2.0.

In the spirit of Web 2.0, I created http://ipv6links.net which is simply a modified version of Scuttle on open-source take on the social bookmarking concept. Each submitted bookmark is checked to verify that it is indeed hosted on a server that at least claims to have IPv6 connectivity (ie. has an AAAA DNS record). The site is dual-stack and reachable via both IPv4 and IPv6. Those connecting via IPv6 will see a blue “6″ in the star at the left top of the page. For those of you without IPv6 connectivity, you can see what you’re missing by loading the site through the SixXS IPv6 to IPv4 web gateway.
