ok, then when i use “tunnels” do i need domain name or can it be from noip?
You’ll need a FQDN that is supported by cloudflare. They support most domains except for a few free ones (e.g. .tk)
May I ask why? Cloudflare is a very reputable company, and as @itsbhanusharma has already said, it’s free. You won’t be charged for anything. Is it because Cloudflare has yet to pull out of Russia? You don’t have to answer me, but I’m quite confused…
