In Address Manager, DNS resource records describe the characteristics of a zone or sub-zone. Address Manager supports the following types of resource records.
| Resource Record Type | Description |
|---|---|
| Host Record | Designates an IP address for a device. A new host requires a name and an IP address. Multiple addresses may exist for the same device. |
| CNAME Alias Record | Specifies an alias for a host name. The alias record type requires a name. |
| TXT Text Record | Associates arbitrary text with a host name. A text record includes name and text information. This record is used to support record types such as those used in Sender Policy Framework (SPF) e-mail validation. |
| HINFO Host Info Record | Specifies optional text information about a host. The host info record includes CPU and OS information. |
| Service Record | Defines services available within a zone, such as LDAP. A service record requires a name, priority, port, and weight. A lower priority value indicates precedence. The port value indicates the port on which the service is available. The weight value is used when multiple services have the same priority value; a higher weight value indicates precedence. |
| Mail Exchanger Record | Designates the host name and preference for a mail server or exchanger. An MX record requires a name and a priority value. Priorities with a lower numeric value are chosen first in assessing delivery options. |
| NAPTR Naming Authority Pointer Record | Specifies settings for applications, such as VoIP. These records are used in Address Manager to populate ENUM zones. |
| Generic Record | The following generic record types are available: A, A6, AAAA, AFSDB, APL, CAA, CERT, DHCID, DNAME, DS, IPSECKEY, ISDN, KEY, KX, LOC, MB, MG, MINFO, MR, NS, NSAP, PTR, PX, RP, RT, SINK, SPF, SSHFP, TLSA, WKS, and X25. These records contain name, type, and value information. |
