Abstract
An IP address of a received data packet is determined. An IP address map that stores set membership values indicative of whether an IP address is a member of a set of IP addresses, for every possible IP address within an IP address space of the IP address, is accessed to determine set membership for the IP address of the data packet. A further action to be performed on the packet is determined based on the set membership that is determined for the IP address of the data packet. Embodiments could be applied to source IP address filtering, destination IP address filtering, or both. Blacklist and whitelist embodiments, and associated further actions that could be applied to packets in such embodiments, are contemplated.
