An Interface can receive an IPv6 An Interface can receive an IPv6 address from each network it seesaddress from each network it sees
Multiple IPv6 Addresses per Interface Uniqueness: Use of Pseudo-MAC Address
MobilityMobility Always use the same IPv6 address Always use the same IPv6 address
regardless of the network it seesregardless of the network it sees It Acquires a Dedicated “Home Address” Use of Source Routing – Efficient in IPv6
