A53 is configured to supports the following record types:
| Record Type | Description |
|---|---|
|
A |
The A record contains an IP address. It is stored as a decimal dotted quad string, for example: ‘203.0.113.210’. |
| CNAME | The CNAME record specifies the canonical name of a record. It is stored plainly. Like all other records, it is not terminated by a dot. A sample might be ‘webserver-01.yourcompany.com’. |
| TXT | The TXT field can be used to attach textual data to a domain. Text is stored plainly, PowerDNS understands content not enclosed in quotes. |
| MX | The MX record specifies a mail exchanger host for a domain. Each mail exchanger also has a priority or preference. For example 10 mx.example.net. In the generic SQL backends, the 10 should go in the ‘priority field’. |
| SRV | SRV records can be used to encode the location and port of services on a domain name. When encoding, the priority field is used to encode the priority. For example, _ldap._tcp.dc._msdcs.conaxis.ch SRV 0 100 389 mars.conaxis.ch would be encoded with 0 in the priority field and 100 389 mars.conaxis.ch in the content field. |
| PTR | Reverse pointer, used to specify the host name belonging to an IPv4 or IPv6 address. |
| ALIAS | The ALIAS pseudo-record type is supported to provide CNAME-like mechanisms on a zone’s apex. |
