Frequently asked questions

How can I test to make sure I have set up my subdomain correctly?

An easy way to test if your new subdomain is representing your traffic is to configure a firewall rule and check if the firewall is working. You can create a new Cloudflare firewall rule that blocks your new subdomain. For the hostname, use the exact address of the new subdomain and block all visits. Save this firewall rule and use an Internet browser to visit your subdomain. If it works correctly, you will receive an error message when you try to visit the subdomain. After testing, be sure to delete the new firewall rule. If you don’t do this, all visits to your new subdomain will be blocked.

How do I redirect a subdomain to the root domain?

If you want to redirect traffic from a subdomain to the root domain, you will need to create a DNS To proxy record for the subdomain. The A record can point to any IP address because all traffic is already redirected before reaching the address.

You can also use bulk redirects. You will need to use subpath matching and preserve the matching suffix to ensure that traffic is routed correctly.

Are my subdomains protected with an SSL Certificate?

As long as your root domain uses Cloudflare’s Universal SSL Certificate, the answer is yes. The certificate covers all top-level subdomains. For deeper level subdomains, you can purchase Cloudflare Advanced Certificate Manager, which covers more than one level of a subdomain.
