IPv4 -> IPv6 "bridge" ?

[Xavier Beaudouin]

Hello,

The thread about IPv6 Future, how will you solve IPv4 connectivity, is for me also a problem.

I operate a new born cloud computing company in France (we do only this kind of business, exclusively), and we have the problem of IPv4 exhaustion...

We had an idea to do IPv6 only on all hosts and create a kinda bridge with our /21 (at starting) to do IPv4 -> "internal" IPv6 host that must be reachable from IPv4 "old internet", also this mapping has to be done in direction IPv6 host -> IPv4 when this host needs to reach some IPv4 stuff.

Unfortunatly it seems to be not easy, even in the free world (for example OpenBSD...)...

Anybody has some pointers, rfc or what else to implement that ?

Also we don't want dual stacks, VPN and some fscking from people that using too mutch RFC1918 networks will gave some ipv4 collisons... That's why we want to force end users to use IPv6 exclusively (since there is as least 2 ISP that provide native or near native IPv6 connectivity in France), this can be "the ipv6 killer application" to force the world to move really to IPv6....

Regards,
Xavier
