Communication with the TRT element is initiated from the IPv6 side via a
special destination address type (a 64-bit prefix along with the IPv4 address of the
destination node inserted in the last 32 bits of the address). Routing information in
the IPv6 network is configured to route this prefix toward the dual-stacked TRT

final destination. e mechanism can be extended to handle sessions initiated in
the opposite direction, but this extension is not addressed in the RFC.
