NAT-PT
Although it is not technically a tunneling protocol, one of the methods of abutting IPv6 and
IPv4 networks is a apparatus accepted as Network Address Translation-Protocol Translation
(NAT-PT), authentic in RFCs 2765 and 2766. NAT-PT works by assuming a array of gateway
function at the IPv4/IPv6 boundary. At that boundary, NAT-PT translates amid IPv4 and IPv6.
This adjustment permits IPv4 hosts to acquaint with IPv6 hosts and carnality versa after the need
for those hosts to run bifold agreement stacks.
Much like NAT and PAT (NAT overloading) for IPv4, NAT-PT supports changeless and dynamic
translations, as able-bodied as anchorage translation.
