Abstract
Dual stack and/or multi-homed devices networked in a device connectivity architecture include a network location signature field in multicast device or service advertisement or announcement messages for recipients to disambiguate announcements of different addresses for the device. The network location signature is a value representing the device's current network configuration (e.g., set of active addresses), and changes with the network configuration. A recipient control point in the device connectivity architecture can then determine whether announcements of different addresses for the device or service are in addition to a previous announced address, or supercedes any previous announced address.
