I don't see the point in working on the /64 case—if that's all we're trying to accomplish, we've already accomplished it. The interesting work Homenet is doing is in fact trying to solve the prefix distribution and automatic setup problem. It's true that this is a hard problem. It's also true that if we don't specify a solution, people will attempt to solve it in their own ways. And if they do that, we will wind up in the situation that Jim found himself in with his broken box with its own built-in DHCP server. BTW, a little more on that topic: the reason that two DHCP servers on the same wire broke Jim's network in a flaky way is that IPv4 doesn't handle the multi-homing case. IPv6 deliberately places the multi-homing case in-scope. This creates a bit of a problem for legacy apps that do not support multi-homing, but it also creates the winning situation that if one device is advertising a provisioning domain that doesn't work, applications that do correctly handle multi-homing will simply use a different provisioning domain. _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
