I want to creat one domain with two or three infinityfree domain. Now i have one parked the painting-persta.rf.gd domain for VIP42.ir via Cloudflare CDN, and if possible want to set another of infinityfree ID for example 61sxdssl.epizy.com as forum subdomain of vip42.ir site which would be forum.vip42.ir. The below photo is showing it for example:

So I want to know is it possible and if yes how could do it?

Thanks.

I’m sorry, but this is not possible.

You can only add the full domain name, so vip42.ir as an Addon Domain or Parked Domain. After that, you can add subdomains of your own domain (like forum.vip42.ir) on that same account through the Subdomains menu. Adding it on another account is not possible I’m afraid.
