Blackhole. DDoS attack

CATNIX launches Blackhole service

The Catalonia Neutral Internet Exchange Point (CATNIX) has put the Blackhole service into operation for its members.

Distributed denial-of-service attacks (DDoS) congest the links of attacked operators. Blackholing consists of sending the traffic to a specific address in which this traffic is discarded. In case of DDoS attack, sending the traffic from the addresses attacked to a blackhole allows to decongest the lines and work normally on the rest of the network.

With the installation at CATNIX of a blackhole server and the configuration of the service on the route-server of Campus Nord, CATNIX members can send the traffic of their IP attacked addresses to the blackhole, decongesting those attacked lines. In this way, traffic is redirected to the blackhole server and the switch is filtered so that it does not reach its destination, mitigating DDoS attacks.
