In fact, the RANGI proxy borrows some idea from the map&encap approach to support communication between RANGI-aware hosts and legacy IPv4/v6 hosts. To some extent, the map&encap can be considered as transition strategy for a host-based id/locator split approach.That's to say, the Strategy A and B (Herrin's Taxonomy)can be complementary.
