Delegation chooses the right place
Nameservers identify where the domain’s authoritative DNS answers live. Records describe connections: A and AAAA point to IP addresses, CNAME maps an alias and MX identifies incoming mail servers. TXT also supports verification and email authentication.
When the domain uses our nameservers, your account editor manages its ClouDNS zone. With external nameservers, edit records at that provider: changing a non-authoritative zone will not update your public website.
Before changing nameservers
Copy website and mail records to the new zone. Include subdomains, verification records, SPF, DKIM and DMARC. Check DNSSEC before moving: delegation with mismatched keys can stop resolution.
Resolver caches may show previous answers until TTL expiry. Keep old services during the transition and test the website, incoming email and outgoing email separately.
