We can already do dual stack - that's not really a problem. I was really rather hoping to avoid the giant NAT box. I'll take a look at DS Lite and or NAT64/DNS64 and see if that makes any sense. Both DS-Lite and NAT64 contain some form of a «giant NAT box» as part of the solution, I'm afraid. Same shit, different wrapping.
You might want to look into MAP, which to the best of my knowledge is the only solution that facilitates IPv4 address sharing between subscribers without any form of (centralised) NAT.
Running dual stack to residential consumers still has huge issues with CPE. It's not an environment where we have control over the router the customer picks up at Walmart. In that case, running IPv6-only to your subscribers isn't a realistic proposition at this point in time. Unfortunately. If you're running out of IPv4 addresses, you better try to get your hands on more of them, somehow, or start planning for the «giant NAT box» you're going to need.
Alternatively, you could begin providing all your *new* subscribers with managed CPEs that support DS-Lite, MAP, NAT64/DNS64/464XLAT (or whichever other IPv4 life-support technology you end up choosing), while at the same time letting your old subscribers with their IPv4-only Walmart CPEs hang on to their public IPv4 address for as long as they need it.
Best regards,
Thanks for the help. We are actually in decent shape with respect to IPv4, probably at least 1 if not 2 years at current growth rate. We can deliver dual stack with public IPv4/6 to customers now. This is the planning stage for <<giant NAT box>>, assuming there are no better options. We are starting to provide some customers with managed CPE and your alternative suggestion may be the way to go. There are several other business/management/support advantages to Amplex supplying the CPE. This may be reason enough to expand that program. I didn't really think we would be able to run IPv6 only in the near future but wanted to make sure I wasn't missing something obvious. -- Mark Radabaugh Amplex mark@amplex.net 419.837.5015
