The difference with v6 is it's designed from the start to work with multiple addresses on an interface. The source-address selection rules are rather complex but they do mean you can hand out a ULA prefix as well as a globally routable prefix, machines will use the ULA for accessing internal resources but will use a globally routable address for accessing external sites.
