I can understand spotify, but don't really understand why waze
would have a problem unless they're doing some sort of rendezvous
like protocol that embeds ip addresses. That said, I'd say that the
vast majority of apps don't have this sort of problem and will quite
unknowingly and correctly work with v6.
