Abstract:
1. An Internet protocol (IP) filter, comprising processor-executable instructions that, when executed on a processor, perform the following steps: monitoring Internet protocol data packets transmitted from one or more clients to a server; obtaining a network address from an IP data packet transmitted by a client; processing IP data packets from the client if a Network address that is uniquely associated with the client is stored in a client table; if the first Network address is not stored in the client table, retrieving a client limit value from a client limit field, the client limit value indicating a maximum number of unique clients for which IP data packets can be processed; if the number of Network addresses in the client table is greater than or equal to the client limit value, transmitting a signal to each Network address listed in the client table; and if a client at a second Network addresses does not respond to the signal, removing the second Network address from the client table, inserting the first Network address into the client table and processing IP data packets from the first client.
