List of Cloudflare IPs is not up to date

[user6154]

Hi everybody,

I need to record the true ip of my visitors on my server which is using cloudflare.

I followed this guide (nginx)
https://support.cloudflare.com/hc/en-us/articles/200170786-Restoring-original-visitor-IPs-Logging-visitor-IP-addresses-with-mod-cloudflare-

I also checked this
https://www.cloudflare.com/ips/

The problem is that I’m still seeing cloudflare ips in my logs, such as this one:

172.68.198.109

Is there any way to get an updated list of cloudflare IPs?

172.64.0.0/13

I didn’t know much about ip ranges, I found an IP Subnet Calculator and now I understand

No worries. https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing goes into details.
