Blocked IP addresses

Blocked IP addresses

In the event of a massive attack on a server that negatively impacts the network infrastructure, the server's IP address can be blocked for all incoming traffic using blackhole (RTBH).

The lockout is for 8 hours and can be extended if the attack continues. You will receive a ticket when a lockout is imposed.

View blocked IP addresses⁠

1. In the Control panel, on the top menu, click Products and select Network Incidents.
2. Open the Blocked IP Addresses tab. The blocking period is displayed for each blocked address.

Unblock an IP address⁠

1. Wait for the blocking to end — it lasts for 8 hours and is removed automatically if the attack has stopped. If you need to remove the lockout sooner, create a ticket and wait for a response from support with recommendations on the necessary actions.

2. Optional: to prevent re-attack and blocking:

   • change the IP address of the server;
   • connect another type of protection.
