So yes, as Ole says, this is solvable.
We can't use the IPv4 experience as a guide here. 99.9% of home networks are behind a NAT so they have stable internal addressing even when the external address changes on every reboot of the NAT. We need to ensure that there is stable internal addressing (ULA helps here). Addresses used to reach external servers however can change without much worry. > The problem for larger corporate networks, especially multi-office > companies, is *much* harder.
