Note: Reverse zone names that contain configuration issues are indicated with an orange
exclamation mark next to the name. You can hover over the reverse zone name to display

Note: After adding new zones, the Distributed DDNS system needs to synchronize all the data
between nodes in the system in order to successfully process dynamic updates. You can
see whether the synchronization process has completed in log messages for the Data and
Service nodes. For more details, see Making sure that data is synchronized between Distributed DDNS nodes.
