I have a Cloudflare DNS service question.

I have a Cloudflare DNS service question.

  1. We have 500 customers.

  2. I want to create 500 subdomains.

ex) user001.mydomain.com


  1. Each customer’s PC tries to update the customer’s PC IP to Cloudflare DNS using [Cloudflare DNS API] every morning.

Is the above situation possible?

  • What is the maximum number of subdomain records?
  • Are there limits on API calls?

There’s no individual record level permissions on Cloudflare. You would need to implement your own API to accept change requests and then using the valid request data from a customer call update the record using your Cloudflare API credentials.
