DNS resource records provide information about objects and hosts. DNS servers use these records to respond to queries for hosts and objects.
You can perform the following actions:
The following table describes the DNS record sources in BloxOne DDI, including combined sources.
| Record Source | Description | Record Types |
|---|---|---|
| Static | Record created manually in UI or by an API call. | All record types except SOA. |
| Dynamic | Record created automatically by a dynamic DNS update. | All record types except SOA. |
| System | Record created automatically upon name server assignment or zone creation event. | A, PTR, NS, SOA. |
| Static, System | A case when a record was created manually, and then, at some point, the zone was assigned to a name server, which resulted in the creation of a System record. | A, PTR, NS, SOA. |
| Dynamic, System | Record created through a dynamic DNS update, after which the zone was assigned to a name server and corresponding System record was created. | A, PTR, NS, SOA. |
You can see those in the Record Source column of the Resource Records Viewer for a specific zone.
Updates to a Static, Dynamic, or System record over API or dynamic DNS do not change the initial record source.
System and combined records have some limitations that include:
- You cannot enable or disable System records.
- You cannot delete System records.
- You cannot modify the record data (RDATA).
