| Type | Description |
|---|---|
| SOA | This is the Start Of Authority for the zone. This identifies this name server as authoritative for this zone. It also contains other information, including the TTL (Time To Live) and a serial number. |
| A | This record resolves a name to a IPv4 IP address. |
| AAAA | This record resolves a name to a IPv6 IP address. |
| NS | This record specifies the Name Servers for a domain. |
| MX | An MX record contains the name of the mail server for this domain. |
| CNAME | This is a canonical name, which is an alias for another name. The name server should return the CNAME record and continue the DNS process for the name that it points to. |
| PTR | This is a pointer to another name. Unlike CNAME the PTR record is returned with no further resolution. |
| TXT | This is traditionally human readable information, but is frequently used for other things, like SPF (Sender Policy Framework) records. The SPF (Sender Policy Framework) is used by some mail servers to help identify spam emails. |
| SPF | This is a newer alternative to storing SPF data in a TXT record. |
