Subdomains that have been Cloudflare-enabled are marked with an orange cloud. This means they will pass through the Cloudflare system, and benefit from all its advantages. If you purchased a Business Pro hosting package, and activated Cloudflare, Cloudflare Railgun will also be automatically activated as well. Subdomains that are not Cloudflare-enabled are marked with a grey cloud.
Only A and CNAME records have the option to be powered by Cloudflare, meaning that only A and CNAME records may show an orange cloud. However, not all A and CNAME records are appropriate to pass through the Cloudflare system. Cloudflare makes suggestions for which records should be orange, but you can easily change this by clicking on the cloud.
To decide which records pass through the Cloudflare network, you need to understand what type of content appears on that subdomain.
You should enable Cloudflare for any subdomain that gets web traffic. You should not enable Cloudflare for subdomains that handle non-web traffic, such as mail, ftp, and ssh. These types of records should be marked by a grey cloud.
Note: If you purchased SiteLock Perform or SiteLock Shield, DO NOT enable Cloudflare because it will conflict with the Content Delivery Network (CDN) that is included in your SiteLock package.
To view Cloudflare’s protection options, please log into your Cloudflare dashboard and go to Your Websites -> Settings -> DNS Settings.
