You can find the full list here: http://www.worldipv6launch.org/participants/?q=1

P.S. It’s a good moment to choke your provider’s lines asking for native IPv6 support

Debian Wheezy Raspberry Pi minimal image

I made my own Raspberry Pi custom image based on Debian Wheezy.

IPv4 vs IPv6 1Gbps network performance

Netperf is a benchmark that can be used to measure the performance of a network. I did a simple test over a 1Gb/s ethernet link to compare IPv4 and IPv6 overhead, here are the results:

~ # netperf -4 -H 192.168.2.1 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.2.1 (192.168.2.1) port [...]

Also, the whole local network is IPv6 ready too: that [...]
