I have a subdomain on the origin server common-name-subdomain.domain.com and I don’t want to expose it as it’s a common name and can be easily guessed and I can not change the subdomain name in the origin server. I want to rename it as something else which can not be easily guessed cnsd.domain.com.
What type of record should be created in Cloudflare account so that I will not expose my origin server IP/Common_name_subdomain to the world, and I can proxy it to the original common_name_subdomain server.
Here IPs to all the subdomains are common.
