IPv4-compatible address

IPv4-compatible address

IPv4-compatible IPv6 addresses used to constitute a special class of IPv6 addresses. Such an IPv6 address has its first 96 bits set to zero, while its last 32 bits represents an IPv4 address.

This address type has been deprecated by RFC 4291.

The only remaining use of these addresses is to represent an IPv4 address in a table with fixed size members that must also be able to store an IPv6 address. It should never been seen on the wire.

The undefined IPv6 address :: and the loopback IPv6 address ::1 are not really IPv4-compatible addresses, even though they are included in the IPv6 address space ::/96.
