Unregistered CloudFlare IPs filling my nginx logs

Hi

I started to note my access.log from nginx has a lot of references coming from 172.68.XX.XX and by looking up these addresses with different tools to see what’s the origin, everything pointed to CloudFlare network.

However, these ranges aren’t included in the Official CloudFlare IP ranges as seen at https://www.cloudflare.com/ips

So, I am unable to restore the original and lost a bunch of useful visitors data.

Please advise. Why are these new ranges unpublished?

As you can see by using a CIDR range explainer, 172.64.0.0/13 includes all the ranges from 172.64.0.0/24 to 172.71.0.0/24

Thanks! I need to get back to school :slight_smile: and refresh that chapter.
