RE: IPv6 for Websites

"Those customers have a lot of devices, usually 2 of which per site need an IP which cannot be NAT'd, because a direct connection is required for management and billing purposes."

I have vpn's to many sites from ASA 5540's for this purpose... in some places that if I screwed up, you would not have lights in your home :)

I can assure RFC1918 scales to the largest networks in the world.

The IP routing folks want IPv6 because they see billions (ok Trillions) being spent on Iphone, ipads, mac air's and they want their share... it's cool.

The killer app for Networking would be physical connectivity lines that never go down... can we get that and keep our IPv4 space?

My company has a lot of customers. Those customers have a lot of devices, usually 2 of which per site need an IP which cannot be NAT'd, because a direct connection is required for management and billing purposes. RFC1918 space is not enough, so they were addressed using real ipv4 space. Since
6/6 this year, we have been migrating management IP's to ipv6, allowing us to reclaim ipv4 space. This means we're not feeling the ipv4 glut and stinginess from ARIN anywhere nearly as bad as other folks.

While we were building the network out to deploy ipv6 for those devices, we also built in the capability to hand customers ipv6 addresses publicly, not simply for internal management and billing traffic. All we need to do is flip the switch, and they'll be handed public ipv6.

As ipv4 space becomes less available, the prices for ipv4 space will rise.
We may be able to use our reclaimed ipv4 space as another revenue stream for the holdouts who refuse to transition. You will also find things like prefix hijacking start to become more prevalent.

Ipv6 is coming, and you're coming with us whether you like it or not :) I know it's hard to believe, but there is a real and honest need for ipv6.
The real hold up is (and for the foreseeable future, will be) application and security support.
