BGP Communities

We have configured some BGP communities which you can use when announcing prefixes.

65535:666 - Remote Triggered Blackholing

Use this community to send us IPv4 /32 or IPv6 /128 routing information, and we will apply next hop 169.254.99.99 or 100::1 which will be dropped in our network if you experience a DoS attack sourcing from us.
Do NOT add any additional communities to the prefix when using this community, otherwise the blackholing will not work (for example, no-export or no-advertise communities will prevent the blackholing from working and we will apply them automatically).
Please note that all traffic to this destination (one of your IP addresses) will be dropped.
