Assuming this is not direct traffic to your IP people will say it is because of TLS logs. Maybe it is in your case. But if you spin up a CF worker on a subdomain to it you will also get hit by traffic immediately. And those certificates are wildcards. I think CF leaks subdomains in some cases. Never seen this behavior when using CF just as a DNS server though.
