Abstract: Previous solutions to the problem of maintaining up-to-date network device addressing, fail to provide systems or processes that efficiently share and obtain addressing information of networking devices in a given network. By contrast, and to that end, various implementations disclosed herein include systems, methods and apparatuses that generate a registry request message, where the registry request message includes a first portion characterized by a first write privilege and a second portion characterized by a second write privilege different from the first write privilege. The systems, methods and apparatuses convey the registry request message to a shared contact point network entity, and obtain a response message addressed from the shared contact point network entity, where the response message includes peer addressing information corresponding to one or more peer network devices associated with the aforementioned systems, methods and apparatuses.
