What happens with Subdomains

Hi, I just setup my domain. My question is,
what happens with the subdomains? Because on my domain I only use an index file witch redirects users to my subdomains(filtering the ip and then redirects user to the right subdomain). Do I have to register all my subdomains somehow on cloudflare, or what?

thanks in advance

All sib Domains need to be properly configured on the DNS Page with A, AAAA or CNAMEs

Hi @atr0x23,

They will need to match whatever you had set up with your DNS provider before switching to Cloudflare.

Probably an A record pointing to the IP of your server, but not sure!
