Overview

Address Family Translation (AFT) is a transition technology for communication between IPv4 and IPv6

networks.

As shown in

1012HFigure 297, the AFT router performs address and protocol translation between IPv4 and IPv6

networks. With AFT, IPv6 and IPv4 hosts can communicate with one another without having their

configurations changed.

AFT allows an IPv6 host to initiate communication with any IPv4 host, but allows an IPv4 host to initiate

communication with only IPv6 hosts whose addresses are IVI addresses. For information about IVI

addresses, see "

1013HIVI prefix and IVI address."
