If you have a dedicated box or service card for NAT, you have a specific NAT expense. If you can buy a smaller box for half the cost, you've saved a specific amount of money. I know of mobile carriers who NATted every Internet connection in IPv4, and have halved their capital expense on NAT. >> IPv6 deployment in your network might mean you can sell some of your >> IPv4 addresses, a clever way I've seen to fund the transition. > That I agree with.

It needs to be implemented first in a deployable state. "Deployable"? It's been deployed by the millions.

Obviously $30,000 was a made-up number for the example. I don't know what "dangling set of apps" you mean that can't be converted, especially in the context of "How much would it cost to add IPv6 support?" >> In another message on this thread I noted that small ISPs are squeezed >> between CPE and IPv4 purchases.

Is there an ISP association trying to do that already? Not that I know of. If there's interest, I'll support, maybe organize. Lee
