The present invention describes an access node for communication in a telecommunication network comprising: an input/output unit adapted for receiving a first information message, wherein the first information message comprises a logical address associated with a virtual network node, a processing unit for extracting the logical address of the virtual network node and for determining a hardware address associated with the logical address of the virtual network node, where the processing unit is further adapted for a determining a logical address of an end-user host communicating with the virtual network node, wherein the access node is configured to transmit a second information message comprising the logical and hardware address of the virtual network node to the logical address of the end-user host. Also, a network infrastructure where the access node is operating is described. The access node also implements a method of the present invention by means of a computer program comprising instruction sets for implementing the method steps of the invention.
