World IPv6 Launch

Tonight, 6th of June at midnight, one year after the World IPv6 day, major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services for the World IPv6 Launch.

One year after the World IPv6 day, our website is still IPv6 enabled. There is no reasons for us to stop the IPv6 adventure…

This Time It is For Real! Happy IPv6!

exp-Networks is IPv6 ready

Our website is IPv6 enabled and is registered to take part to the World IPv6 day. During that day major websites will offer their content over IPv6 for a 24-hour “test flight”.
You can test your IPv6 connectivity by checking the logo here above…
On our side, we’re assuring this website is still IPv6 reachable via the IPv6 Forum certification program:

6in4 Tunnel

Thanks to company like Hurricane Electric or SixXS it is very easy to connect to IPv6 Internet backbone even if your ISP does not provide native access to IPv6. Those companies provide free access to their tunnel brokers. A tunnel broker is a dual homed router connected to IPv4 Internet backbone on one side and to IPv6 backbone on the other side. The concept is quite simple, you have access to the IPv4 world and you want to access the IPv6 world. You just need to build a 6in4 tunnel from your DSL router or from your PC or actually from whatever IPv4/IPv6 capable you want to the tunnel broker on the IPv4 side and you’ll encapsulate your IPv6 traffic into that tunnel. The broker will decapsulate your IPv6 packets and send them to the IPv6 Internet backbone. The tunnel broker will also advertise your IPv6 range to the backbone in order to allow the traffic to flow back to your 6in4 tunnel. [Read more]

IPv6 Firewall with Linux

More and more server hoster have configured IPv6 on their network. And most of their Linux based servers come with a basic IPv6 configuration. Even if IPv6 is not used, it is there and widely open as the netfilter/iptables default policy is ACCEPT. [Read more]
