If the delegated prefix changes, you'll be simply postponing the local communication failure, not prevent it. I've run Homewrt for over a year now and have no shortage of annoying experiences like for instance a movie that is being streamed to my HTPC from my NAS just suddenly freeze just because the Internet uplink have gone down and/or the delegated prefix changes. The last year has convinced me that the best user experience is achieved by having an in-home stable ULA prefix to complement the ISP-delegated global prefix[es] [if any], and that all the internal hostnames should resolve to the IPv6 addresses assigned from the ULA prefix.
