What is a nullroute?
Posted by Raimundas S., Last modified by Vytautas K. on 09 May 2018 10:55 AM
A nullroute or null route or blackhole route is a route for an IP address that goes nowhere. The reason for creating a null route for your IP address is to prevent your server from receiving or sending any data over the internet.

The nullroute is activated for server's IP address if big DDoS attacks are detected. Server can be temporarily disconnected from the internet in order to prevent harm to whole infrastructure and Bandwidth over-usage for particular server.

Normal internet connectivity is restored to server automatically after the DDoS attacks stop.
