Cloudflare WARP IP ranges

Application Performance DNS & Network

Hi,

in our datacenters, we have some kind of DDoS protections which are based on limiting of open TCP/UDP connections from IP subnets like /16, /8, etc. We have very strict limits especially for IP addresses outside our country.

Yesterday I saw, that a few Cloudflare WARP IP addresses are on our blacklists due to hundreds open connections to our websites (for example: 8.46.113.12, 8.6.146.6, 8.21.9.64).

Can you provide or publish all Cloudflare WARP IP ranges? I would like to add them to our IP whitelist. Thank you.

I found, that ASN of Cloudflare is AS13335, so here is complete IP list of Cloudflare company: AS13335 Cloudflare, Inc. details - IPinfo.io

IP ranges in my origin post are included so this list is proper, but it would be better to have IP ranges only for WARP.
