Not exactly, as most enterprise operators avoid NAT like the plague when they have a choice. Address scarcity has never been an operational problem in the enterprise and in fact, what the enterprise user community is asking for is not NAT but what NAT provides which is mostly two things: a) portable and stable address space and b) scoped addresses. Since they can't get either one with IPv6 they fall back to the next best thing which is NAT, despite its loads of problems. If they ever deploy IPv6, that is. Michel.
