A communication system and method include an intermediate router arranged to facilitate communication between any of a plurality of communication nodes over a data communications network. The intermediate router receives communications over the data communications network from a transmitting communication node for a receiving communication node. The communication includes a unique identifier of the transmitting and receiving communication node. The intermediate router includes a routing database, and is arranged to record the unique identifier of the transmitting communication node against the network address of the transmitting communication node from which the communication was received. The intermediate router is also arranged to route communications to receiving nodes by obtaining the recorded network address associated with the unique identifier of the receiving node and routing the communication to the recorded network address. The unique identifier is independent of the network address of a node to cater for changed in network address.
