Orange Clouding with Secondary DNS

Secondary DNS is a backup system for primary authoritative DNS servers, ensuring redundancy and synchronization of records across multiple servers. It can be used in various ways such as passive or active backups, and with hidden primaries. Secondary DNS Override enhances this by allowing users to proxy A/AAAA/CNAME records through Cloudflare's network while maintaining the primary server's control over record changes. This feature is particularly useful for those who want to leverage Cloudflare's security and performance services without transferring all their zones to Cloudflare DNS as a primary provider. Secondary DNS Override is currently available on the Enterprise plan, with additional documentation provided in support articles.
