A network device may be configured to provide a gateway between a remote host and a mobile node using multiple interconnection protocols. The network device may include database circuitry configured to query a database for a first or second address of a mobile node using a domain name of the mobile node. The addresses may be associated with different interconnection protocols. The network device may include communication interface circuitry configured to receive a request from a remote host to communicate with the mobile node. The request may include the domain name. The interface circuitry may also be configured to transmit a message indicating the request using the first address, and transmit the second address to the remote host so that the remote host can communicate with the mobile node using the second address. The message may include a command to establish a data bearer through the second address.
