6over4 is an IPv6 transition mechanism meant to transmit IPv6 packets between dual-stack nodes on top of a multicast-enabled IPv4 network. IPv4 is used as a virtual data link layer (virtual Ethernet) on which IPv6 can be run.
==How 6over4 works== 6over4 defines a trivial method for generating a link-local IPv6 address from an IPv4 address, and a mechanism to perform Neighbor Discovery on top of IPv4.
