| SOA | 1 | Name server | The FQDN of the primary Master name server for the zone the record belongs to. Has a special meaning when used with Dynamic DNS (DDNS): called MNAME, it allows the DNS client to know on which DNS server it has to update itself with DDNS. |
| 2 | Responsible | The administrator email address for the zone the record belongs to. |
| 3 | Serial number | The serial number for the zone the record belongs to. The serial number is automatically incremented for each zone change. |
| 4 | Refresh | The refresh delay for the zone the record belongs to, in seconds. When reached, it forces the slave name server(s) to read the SOA record. If this record is higher than the slave's one, a zone transfer will be triggered by the slave to get the latest version of the zone. Typical values are 3 to 24 hours. |
| 5 | Retry | The retry delay for the zone the record belongs to, in seconds. When reached, it forces the slave server to retry the request if it fails to reach the master server during a refresh cycle. Typical values are from 10 to 60 minutes. |
| 6 | Expiration | The expiration time for the zone the record belongs to, in seconds. When reached, the zone records are considered to be no longer valid/authoritative. The DNS server then stops responding to queries for the zone. To avoid a major outage, the typical value is pretty high, between 1 to 3 weeks. |
| 7 | Minimum | The minimum time for the zone the record belongs to, in seconds. It defines the period of time that negative responses can be cached from the slave. For instance, if a request cannot be resolved, the server will answer with a NXDOMAIN result (No such domain). The server will continue returning this value until the Minimum value expires, then it will retry the resolution. This value has to be between 0 and 3 hours. |
| NS | 1 | DNS server | The DNS server hostname. |
| MX | 1 | Preference | A number, between 0 and 65535, to define which server has priority if there are several RRs in the zone. The lowest the value has the priority over the other server(s). |
| 2 | Mail server | The SMTP (mail) server hostname. |
| A | 1 | IP address | The IPv4 Address of the host. |
| AAAA | 1 | IPv6 address | The IPv6 Address of the host. |
| PTR | 1 | Localization | The hostname that should be returned when the IP address is queried. |
| CNAME | 1 | Hostname | The hostname. |
| TXT | 1 | Text | The description of your choice (max. 255 characters including spaces). |
| SRV | 1 | Priority | A number, between 0 and 65535, to define which server has priority if there are several SRV RRs in the zone. The lowest the value has the priority over the other server(s). |
| 2 | Weight | A number, between 0 and 65535, that defines the server weight. If two SRV RRs have the same priority, the weight defines which server is more used. The field gives priority to the SRV RR with the greatest weight value: the greater the value is, the more the server is solicited. If you type in , there is no weighting. |
| 3 | Ports | The port number that delivers the service to the target. |
| 4 | Target | The hostname of the server delivering the service. |
| HINFO | 1 | CPU | The name of the CPU, either , , , , , , , or . |
| 2 | OS | The name of the operating system, either , , , , , , , , , , , or . |
| MINFO | 1 | Responsibleemail | The email address of the administrator of the mail list. |
| 2 | Error email | The email address that should receive the error messages regarding the mail list. |
| DNAME | 1 | Domain | The domain name of a subdomain of the zone. |
| AFSDB | 1 | Preference | Type the version of AFS service used: (AFS version 3.0) or (OSF DCE/NCA version). |
| 2 | AFS server | The AFS hostname. |
| NAPTR | 1 | Order | A number, between 0 and 65535, to define which RR has priority if there are several NAPTR RRs in the zone. The lowest the value has the priority over the other record(s). |
| 2 | Preference | A number, between 0 and 65535, to define which RR has priority if there are several NAPTR RRs have the same order in the zone. The lowest the value has the priority over the other record(s). |
| 2 | Flags | The string that corresponds to the action you want your client application to perform. The flag specified impacts the data expected in the field , and/or . |
| 3 | Services | The services parameters to which applies the action specified in the field . You must respect your client application syntax. |
| 4 | Regex | The string that contains a substitution expression matching the format to which applies the action specified the field . |
| 5 | Replace | An FQDN domain name to which applies the action specified the field . You can specify no domain name if you type in (dot) in the field. |

| NSAP | 1 | Name | The NSAP address of the end system. It should start with and not exceed 255 hexadecimal characters separated by dots. |
| DS | 1 | Key Tag | The parent zone DS key tag. |
| 2 | Key Algorithm | The parent zone DS algorithm key. |
| 3 | Digest Type | The parent zone DS digest type. |
| 4 | Digest | The parent zone DS digest. |
| DNSKEY | 1 | Flags | The zone key flag. |
| 2 | Protocol | The protocol value. |
| 3 | Algorithm | The public key's cryptographic algorithm. |
| 4 | Key | The public key material. |
| WKS | 1 | IP address | The IPv4 Address of the host that contains the services listed in the Services field. |
| 2 | Protocol | The communication protocol, either or . |
| 3 | Services | The list of needed services. |
