DNS Records
Resource records
| Code | Number | Defining RFC | Description | Function |
| A | 1 | RFC 1035 | address record | Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but also used forDNSBLs, storing subnet masks in RFC 1101, etc. |
| AAAA | 28 | RFC 3596 | IPv6 address record | Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host. |
| APL | 42 | RFC 3123 | Address Prefix List | Specify lists of address ranges, e.g. in CIDR format, for various address families. Experimental. |
| CNAME | 5 | RFC 1035 | Canonicalname record | Alias of one name to another: the DNS lookup will continue by retrying the lookup with the new name. |
| MX | 15 | RFC 1035 | mail exchange record | Maps a domain name to a list of message transfer agents for that domain |
| NS | 2 | RFC 1035 | name server record | Delegates a DNS zone to use the given authoritative name servers |
| SOA | 6 | RFC 1035 | start of authority record | Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone. |
| SRV | 33 | RFC 2782 | Service locator | Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. |
| TXT | 16 | RFC 1035 | Text record | Originally for arbitrary human-readable text in a DNS record. Since the early 1990s, however, this record more often carries machine-readable data, such as specified by RFC 1464, opportunistic encryption, Sender Policy Framework (although this provisional use of TXT records is deprecated in favor of SPF records), DomainKeys, DNS-SD, etc. |
