Setting up my CloudFlare Pro with several subdomains


I’ve just activated a Pro Plan, and I’m trying to configurate the domains.

My domain hosts several subdomains in two different IP addresses: —> —> —>

Additionally, such subdomains have sub-subdomains, pointing to the same IP address as their parents: —>

On the DNS section of my dashboard, shall I add ‘A’ records for each one of the subdomains? I added ‘A’ records for ‘’ (pointing to and the dashboard allowed me to do it. However, I tried to insert it and received the following error message:

DNS Validation Error (Code: 1004): This DNS record cannot be proxied - click the cloud icon to turn it gray to proceed (Code: 9041)

I have no idea about how to configure all the subdomains. Any help is appreciated. Thank you very much.

Can you post a screenshot of your DNS settings and the screen where you are trying to add the record? Redact IP addresses if necessary.


I guess it’s not necessary. I’ve only seen this message when i accidentially tried to proxy private adresses.

Good point, but before having the OP reveal his entire infrastructure I wanted, for starters, to rule out some generally funny DNS business :man_shrugging:t2:.
