Group-based treatment of network addresses

Abstract:

Systems, methods, and computer-readable media are described for a network address block treatment server. The network address block treatment server identifies blocks of network addresses, associates them with treatments, and generates compact representations of the network address blocks. Blocks may be identified based on network activity data or on the treatment of individual network addresses, and treatments may be associated with address blocks based on address-level and/or block-level criteria. Treatments may include, for example, denying service requests, throttling, queueing, issuing a challenge-response, or limiting the number or scope of services. The network address block treatment server may review treatments periodically or upon receipt of additional network activity data. The server may implement treatments in connection with firewall or routing services, or may transmit address block representations and associated treatments to network service providers for implementation.
