In order to be able to use a smaller routing table () and, thus, to reduce the costs and power consumption and to improve the performance of an IP router, it is proposed to extract a destination address identifier (ADR) from a data packet to be forwarded by the IP router, compress the extracted destination address identifier (ADR) by using a lossless data compression algorithm, and compare the compressed destination address identifier with entries stored in the routing table () so as to find a correspondence between the destination address identifier and one of the entries of the routing table (). Each entry of the routing table () corresponds to a possible or available forwarding address of the IP router, the forwarding addresses having been compressed with the same data compression algorithm as the destination address identifier. After having found a correspondence between the destination address identifier and one of the compressed forwarding addresses stored in the routing table (), a switch () of the IP router switches the respective data packet to one of its output links (OUT) which is associated with the respective forwarding address matching the destination address identifier (ADR).
