BlackHole server The Blackhole server allows customers under a DDOS attack to send all traffic to the IP address under attack to null route. To request configuration on the blackhole server: Log into eCogent and click on BGP request. You will need the following information: 1. Order Number. 2. An IP address from your network with which we will peer. 3. A password (all blackhole server sessions are password protected).
All North American and Asia Pacific Customers will peer with: IPv4: 66.28.8.2 and IPv6: 2001:550:0:1000::421c:802 All European Customers will peer with: IPv4: 130.117.20.2 and IPv6: 2001:550:0:1000::8275:1402 Once your session to the blackhole server has been established, any network you announce to it will be stopped at our borders. Please note that Cogent does not warrant or guarantee that use of the blackhole server will mitigate, or minimize any effects of a DDOS attack nor does Cogent guarantee that a session to the blackhole server can be established on a timely basis. You are limited to announcing 50 prefixes to our blackhole server. If you anticipate needing to announce more, relay that request to our Customer Support department along with the technical justification for an increase in the number of prefixes to be announced.
