Methods, systems, and computer readable media for identifying network locations associated with endpoints

Methods, systems, and computer readable media for identifying network locations associated with endpoints are disclosed. According to one exemplary method, the method occurs at a registration server including at least one processor and configured to operate in a public network or a semi-public network. The method includes receiving, from an endpoint, a packet including a payload containing a first address associated with the endpoint. The method also identifying a second address from a header of the packet. The method further includes determining, using the first address or the second address, whether to initiate a connection with the endpoint for determining a network location associated with the endpoint.
