PROBLEM TO BE SOLVED: To manage the IP address range of the entire DHCP server system in a unified way and provide the load dispersion and the redundancy of a plurality of DHCP servers. SOLUTION: DHCP servers A101, B102 share a memory A111. On a DHCP service request from a DHCP client, a single DHCP server having a less number of addresses allotted by each DHCP server provides the DHCP service. Over a network A131 or via the memory A111, each DHCP server checks whether or not the other DHCP server is ready for providing the DHCP service. If there is no server else being ready for providing the DHCP service, it provides the DHCP service, irrespective of the number of allotted IP addresses. COPYRIGHT: (C)2005,JPO&NCIPI
