Looking for an IP Range to enter in the firewall to unblock docker pulls. Currently the firewall is failing connection for production.cloudflare.docker.com

Docker Hub Registry uses Cloudflare as the CDN for serving Docker Image layer blobs, manifests, etc. This means that in order to allow access to Docker Hub through a firewall, you would need to allow-list all of the Cloudflare IPs. Of course, then you will allow traffic from any Cloudflare-based site, which can be a concern.
