DNS Flood my IP

Hello, I have a problem. Cloudflare’s IP is bombing my DNS server with strange entries. i have about 1000 p / s from addresses 104.21.29.222, 172.67.149.216 etc … please help.

Greetings!

I am sorry to hear you are experiencing some issue.

May I ask is Cloudflare allowed to connect to your origin host/server?

Nevertheless, Cloudflare IP addresses list can be found here:

Have you implemented the solution to restore the original visitor IP at your log files on the origin host/server?

Do you see any events being blocked at the Cloudflare Dashboard → Firewall tab?

Are all the hostnames (DNS record) at the DNS tab of Cloudflare dashboard proxied and set to :orange:?

Otherwise, are you under an attack? Kindly take a look at below two articles:

Useful information and articles if so:

Hi.

I don’t use cf for these addresses. I don’t mean proxies, but only connections from CF to my DNS server. I have to block traffic because there are too many connections and they are not wanted by me.
