Abstract
The present invention relates to methods and a system for enhancing DHCP to promote a more secure IP address allocation model. The invention advantageously accomplishes this through the utilization of an address generator which is compatible with the existing DHCP protocol, and which incorporates an algorithm for use in producing a selected IP address as one of a sub-set of allocable addresses that are non-sequentially distributed within an address pool. As such, the invention offers robust security and allows for the rapid detection of unauthorized activity such as network intrusion, worms, virus propagation, network scanners, and SPAM.
