Cloudflare IP ranges list is not current

I am currently running a web server behind Cloudflare proxy, and my origin server’s firewall is set to only allow requests from Cloudflare servers from the text files as listed on the website. However, I notice that it is blocking requests from Cloudflare IP 172.70.206.100, which is not included in the IP ranges list. Can the list be updated as soon as possible? I am unaware as to any other IP ranges that may or may not be omitted from this list.

Hi there,

172.70.206.100 is part of the 172.64.0.0/13 prefix, which is already listed on the page you linked :slightly_smiling_face:

Network: 172.64.0.0
CIDR: 13
Mask: 255.248.0.0
Range: 172.64.0.0 - 172.71.255.255
Total addresses in range: 524288

Thank you, It seems that my firewall was not parsing the text files from the website correctly, and I think I’ve fixed it now!
