How do I whitelist an IP address in Cloudflare?

You can whitelist an IP address through the Cloudflare dashboard. Log in to your Cloudflare account, select your website, and navigate to the 'Security' tab. Under 'Settings', you'll find the 'IP Access' section. Here, you can add IP addresses to the whitelist. You'll need the IP address of the source you want to permit. Be sure to add IPs carefully to avoid blocking legitimate traffic.
