Cloudflare Nameservers
How are Cloudflare's nameservers different from the DNS provided by Google DNS or OpenDNS? Can I delegate to
Cloudflare nameservers while still using my host’s DNS?
Response
Hello
Thanks for reaching out! By allowing Cloudflare to manage your DNS you unlock several security and performance benefits. Take a look at this explainer documentation that better demonstrates why you should use Cloudflare as a proxy or standalone layer: https://developers.cloudflare.com/learning-paths/get-started/concepts/how-cloudflare-works/#benefits
As for the second question, if you mean you can still host your app on a different origin and maintain those records, this is definitely possible. Cloudflare managed your DNS records but you can still CNAME your app to whatever origin provider you desire
Rationale
I highlighted Cloudflare's documentation and walked through the many options they have.
