Thank you.
I've said this repeatedly in many communities and it's like I killed the golden goose - people lose their minds.
I disable IP6 everywhere - my router NATs everything as it is, why have another protocol running if I don't use it?
We'll see what the future brings.
It's great for backbone and public address space - and maybe in enterprise, but there it's a costly transition that won't happen immediately. Things will change as hardware ages out and is replaced.
New infrastructure will be mostly IP6.
And when people leave the office, their machines will connect to, and transit IP4 networks, so they'll still need to address how everything works over IP4 (say VPN connections, any hardware/software that's still IP4 dependent in the data centers, etc).
