  - <span style="color: #000000">**Synchronize secondary zone content**</span><span style="color: #000000">: </span>By default, a secondary DNS zone receives its records directly from an external primary server through standard zone transfer mechanisms (AXFR/IXFR). The secondary server uses this data to resolve DNS queries, but the transferred records are not stored or displayed in the Infoblox portal. As a result, administrators can rely on the secondary server for resolution, but they have no visibility into the actual zone content from within the Infoblox management interface. When **Synchronize Secondary Zone Content** is enabled, Infoblox synchronizes the records of the secondary zone from the supported secondary server and imports them into the Infoblox portal. This allows administrators to view the full set of resource records associated with the secondary zone directly in the portal, alongside other managed DNS objects. The feature is designed to enhances operational visibility, troubleshooting, auditing, and consistency checks across primary and secondary DNS servers. The synchronization may take up to 15 minutes.
