Abstract
An embodiment of the present invention is directed to a method of determining a probable IP subnet of a network. The method includes maintaining a table of possible networks. The entries of the table include respective network addresses, respective subnet masks, and respective scores. The method also includes observing a packet, determining an IP address of the packet, and comparing the IP address of the packet with the respective network addresses of the entries of the table of possible networks. If the IP address of the packet falls under the respective network address of a particular entry, the respective score of the particular entry is adjusted. Otherwise, a new entry is created in the table of possible networks corresponding to the IP address of the packet. The method also includes ranking the entries of the table of possible networks based on their respective scores.
