Embodiments of the present invention relate to coordinating address allocation events at a routing device and at a host machine, where the routing device is arranged to route data between the host machine and at least one other host machine. The routing device may be a router and the host machine may be a computer located in a first network, the first network operating in accordance with a first transmission protocol. The other host machine may be a computer, located in a second network, the second network operating in accordance with a second transmission protocol. The method is particularly suited to situations where the host machine is running one or more applications in accordance with the second transmission protocol. Embodiments of the invention are concerned with coordinating address allocation events that are required to enable data of the second transmission protocol to be transmitted through the first network and on to the other host machine. The method comprises the following steps: receiving an allocated address, for use by the host machine in communicating with the other host machine; receiving an indicator representative of allocation status of the allocated address; sending, to the routing device, the allocated address together with the address of the host machine; storing a mapping between the allocated address and the address of the host machine; monitoring the indicator, and, if the indicator indicates that the allocated address is no longer valid for the host machine, rendering the stored mapping unusable. |
