Abstract
Recognition of users by assigned source port blocks identifies a specific network-attached device using date, time, WAN IP, and source port information associated with a user session. The method includes the steps of: receiving a date, time, WAN IP address, and source port associated with a user session; a computer searching a list of user sessions for one or more LAN IP addresses associated with the received WAN IP address that were in use at the received date and time; responsive to finding one or more matching IP addresses, a computer searching a list of assigned source ports for a match between a set of source ports assigned with the found LAN IP addresses and the received source port; and responsive to finding a matching source port, a computer identifying a source host device that is assigned the matching LAN IP address.
