These addresses hold an embedded global IPv4 address. They are used to represent the addresses of IPv4 nodes as IPv6 addresses to applications that are enabled for IPv6 and are using AF_INET6 sockets. This allows IPv6-enabled applications to always deal with IP addresses in IPv6 format regar...
The dual-mode TCP/IP stack performs the transformation of the IPv4-mapped addresses to and from native IPv4 format. IPv4-mapped addresses have the following format: Figure 1. IPv4-mapped IPv6 address For example: ::FFFF:129.144.52.38...
When the transport layer finds an AF INET6 listening socket, it will pass the packet to the listening socket as if it was from the corresponding IPv4-mapped address. This draft discusses security threats due to this ambiguity of IPv4-mapped address. It also discusses threats due to the ...

AnIPv4-mapped IPv6 addressis an IPv6 address that is used to store addresses from IPv4. The syntax is quite simple, it’s just a normal IPv4 address prefixed by::ffff:, e.g.::ffff:1.2.3.4, this corresponds to the IPv4 address1.2.3.4. ...
