Abstract
A topology map engine obtains, from a dynamic host control protocol relay device, a relayed request, of a client, for a dynamic host control protocol lease. The relayed request has at least one given IP address of the dynamic host control protocol relay device inserted therein. A search is made in a database for that IP address. If not found, dynamic host control protocol relay device information is obtained. This information includes: an identifier of the dynamic host control protocol relay device; and at least one network interface of the dynamic host control protocol relay device and any internet protocol addresses assigned to same. This information is obtained at the topology map engine and stored in the database.
