A practical methodology to detect multiple IP addresses used by a single host on different network interfaces

This document presents a technical-practical methodology to discover multiple IP addresses used by a single host with multiple network interfaces, regardless of using wired or wireless technology. After a brief introduction regarding the protocols involved and the requirements to satisfy, it describes the main steps of the proposed algorithm. Finally it reports an example of implementation to demonstrate its effectiveness. In fact, because of its usefulness it has been integrated into a software instrument used for the management of the CNR research area network in Pisa.
