Security/logs / health checker IP address

We have such thing

The problem is we cant find in logs in our firewall IP = 104.20.147.128

How can we identify the checker in our firewall ? What is the real ip ?

That IP is the one of the record you are checking, it is recommended that you hit the origin directly, non passing through Cloudflare.

$ dig +short www.mirkvartir.ru
104.20.147.128
104.20.148.128

The way to search for it is by checking for user agent, you’ll find something like this from a Cloudflare IP (those listed in www.cloudflare.com/ips):

Mozilla/5.0 (compatible;Cloudflare-Healthchecks/1.0;+https://www.cloudflare.com/; healthcheck-id: {id-of-check})
