Abstract
Systems and methods for blocking spoofed traffic within communications networks include obtaining, at a computing system, routing information for an autonomous system of a communications network, the routing information identifying Internet Protocol (IP) addresses associated with the autonomous system. In response to receiving the routing information, the computing system generates a prefix list based on the routing information, the prefix list including one or more prefixes encompassing the IP addresses identified by the routing information. The computing system then transmits instructions to a network device of the communications network configured to cause the network device to update a filter function of the network device based on the prefix list such that the network device permits network traffic that originates from IP addresses within the prefixes of the prefix list.
