Is there any dns to do the same?(Not an issue)

[heisGarvit]

Almost every device have dyndns integrated in their firmware so is there any dns server that can change the requests to dyndns to cloudflare ?

The idea came from Here . Nintendo closed it's old servers and some people developed their own DNS server and changes the requests made to Ninetendo's server to their own server.

I couldn't find one, but you could write something that accepts dns transfers and converts them to use an api, https://dehydrated.de has a ton of samples and could be used as a starting point. If you used a dns with a database backend you could just query the database for recently changed records and then push them to CF.
