I am not sure if this correct, ipv4 to ipv6 and viceversa is be done by TRT= =20 (RFC3142) routers which are supposed to run on the border of such networks = or=20 by whom provides both protocols, as enduser you do not need to care about=20 connectivity to each protocol=20 > > I'm afraid I couldn't parse the latter part of this paragraph.
