A forwarding engine(40a) obtains packet processing information on a packet and information on a next hop by retrieving the forwarding table(30a) relating to each address group through the IP destination address. An IP lookup system comprises as follows. A routing information collecting and forwarding information generating portion(90) collects routing information through a routing protocol, and processes the collected routing information as forwarding information.
