Claim:
1. A method for routing a message from a first virtual network to a second virtual network without the use of a gateway, the first virtual network having a first plurality of valid virtual addresses some of which being assigned to virtual nodes in the first virtual network, the second virtual network having a second plurality of valid virtual addresses, the method comprising: the first virtual network identifying a destination for a message; the first virtual network accessing an internal record associated with the destination virtual network, the record containing at least the first plurality of virtual addresses that are valid virtual addresses for virtual nodes within the first virtual network, and the second plurality of virtual addresses that are valid virtual addresses within the first virtual network but which are mapped to a plurality of virtual nodes of the second virtual network wherein at least one of the second plurality of valid virtual addresses is not globally unique and is reached by the first virtual network without use of a remote gateway that publishes globally unique addresses for network destinations; the first virtual network determining from the internal record, that the message destination is mapped to a valid virtual address associated with a virtual node of the second virtual network; and routing the message towards the virtual address of the second virtual network.
