Will origin nameserver/IP changes at the registrar automatically propagate to an existing CloudFlareaccount?
Unless you are an enterprise customer with a zone configured as secondary DNS, Cloudflare acts as an authoritative nameserver. This means the authority for records is delegated at your registrar to the designated Cloudflare provided name servers to provide answers for records in your zone.
Thank you for responding.
So, under DNS management in my CloudFlare dashboard, I should copy/paste the site’s new IP on to all of those DNS records?
I found a relevant article, and will follow these instructions. Posting here in case it is helpful for anyone else:
What should I do if I change my server IP address or hosting provider?
After switching hosting providers or server IP addresses, update the IP addresses in your Cloudflare DNS app. Your new hosting provider will provide the new IP addresses that your DNS should use. To modify DNS record content in the DNS app, click on the IP address, and enter the new IP address.
