alt Hacker NewsYou can have /both/ a ULA and a Globally Routable address. In practice it works just fine. My internal DNS points to the ULA for internal connectivity and my hosts use their global addresses for external connectivity.

Ah, you mean for cases where you want both stable addresses (even if only internal) and globally reachable ones (even if non-constant)?
Yeah, that works, but everything gets much easier if your internal DNS can just support the varying prefix natively, e.g. via integration with the external-facing DHCP or PPPoE or whatever other address configuration protocol you use, since then you can reach everything both locally and globally by name.
