In one implementation, a method for managing access to mobile endpoints leverages the always-on nature of a first internet layer protocol to expand the reach of a second internet layer protocol. A network device receives a request originating from a remote host. The request includes a domain name of a mobile endpoint. The network device queries a database using the domain name for a first address of the mobile endpoint as designated according to the first internet layer protocol. The network device transmits a wake up message to the mobile endpoint using the first address. A data bearer for communication with the second internet layer protocol is established based on the wake up message, and a second address is assigned to the mobile endpoint. The second address is forwarded to the remote host, allowing communication between the remote host and the mobile endpoint.
