Dual stack IPv6 for IPv4 depletion

Sun Jul 5 13:57:43 UTC 2015

We are the ISP and I have a /32 :)

I'm simply looking at the best strategy for migrating my subscribers off v4 from the perspective of solving the address utilization crisis while still providing compatibility for those one-off sites and services that are still on v4.

Thanks,

If you're fortunate enough to have a dual-stack ISP already, you can forgo tunneling altogether and just use an IPv6-capable border firewall.

If your ISP can't deliver IPv6, tunneling is the clear path to building a lab. If you have a dual-stack ISP already, the clear path is to use an IPv6-capable border firewall.
