Abstract: The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. A monitoring and mitigation service can characterize a command and control node as compromised or otherwise manipulated for purposes of generating distributed attacks. The monitoring and mitigation service can then identify network mitigation information in the form of null routing addresses that will cause network communications associated with the identified command and control node to be terminated or otherwise not delivered to the intended network-based resources. The monitoring and mitigation service can propagate the null routing address to routing components. The network mitigation information can be associated with expiration criteria for the routing components that receive and implement the network mitigation technique.

Abstract: A system can determine by which path/tunnel an Internet destination can be best reached for a user with an IP address from a static BGP range. The system looks up the destination address in an egress map. This map can either specify a tunnel that should be used for encapsulation for static BGP, or (when tunnel is not present) cause the system to send out unencapsulated traffic, in which the traffic follows normal BGP routing on a border network.
