DNS resource records provide information about objects and hosts. DNS servers use these records to respond to queries for hosts and objects.
The following resource records can be configured in BloxOne DDI:
- Creating a CAA Record
- Creating an NS Record
- Creating an A Record
- Creating an AAAA Record
- Creating a PTR Record
- Creating an SRV Record
- Creating a TXT Record
- Creating a CNAME Record
- Creating an NAPTR Record
- Creating an MX Record
- Creating a Generic Record
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).
