摘要
Described is an IPv6-IPv4 compatibility global aggregatable unicast address format that enables incremental deployment of IPv6 hosts and routers within predominantly IPv4 based networks. A globally aggregatable IPv6 address prefix is associated with an IPv4 node having an IPv4 address and deployed in the network. The IPv4 node is configured with an IPv6-IPv4 compatibility address that includes a prefix portion and an interface identifier portion. The prefix portion contains the IPv6 address prefix associated with the IPv4 node and the interface identifier portion contains the IPv4 address. Packets addressed to the IPv6-IPv4 compatibility address of the IPv4 node are routed across IPv6 infrastructure using the IPv6 prefix portion or tunneled across IPv4 infrastructure using the IPv4 address embedded in the interface identifier portion.
