Abstract
An information broker is provided which receives information regarding the updating of IP addresses and distributes the information to subscribing Domain Name Service (DNS) or Dynamic Host Configuration Protocol (DHCP) servers. A list of subscribing servers is maintained by the broker. The broker may broadcast information regarding the allocation of a IP addresses to subscribing DNS servers, which then may be added to the DNS databases or the database may be updated with the new information. The broker may also broadcast information regarding the revocation of IP addresses to subscribing DNS servers, which may then be used to clear DNS entries in the database. Revocation of dynamically allocated IP addresses in networks with multiple DHCP servers may also be simplified by using the broker, where the broker broadcasts information regarding the revocation of IP addresses to subscribing DHCP servers. Utilization of the broker within a segment of the Internet allows a user to determine the dynamically allocated IP address of a user within the segment simply by making a standard DNS query.
