NAPTR : Naming Authority Pointer ( RFC 3403)
Allows regular expression based rewriting of domain names which can then be used as URIs, further domain names to lookups, etc. |
AAAA : IPv6 address record ( RFC 3596)
Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host. |
TXT : Text record ( RFC 1035)
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, DomainKeys, DNS-SD, etc. |
DHCID : DHCP identifier ( RFC 4701)
Used in conjunction with the FQDN option to DHCP |
SIG : Signature ( RFC 2535)
Signature record used in SIG(0) (RFC 2931). Until RFC 3755 was published, the SIG record was part of DNSSEC; now RRSIG is used for that. |
NSEC : Next-Secure record ( RFC 4034)
Part of DNSSEC—used to prove a name does not exist. Uses the same format as the (obsolete) NXT record. |
PTR : pointer record ( RFC 1035)
Pointer to a canonical name. Unlike a CNAME, DNS processing does NOT proceed, just the name is returned. The most common use is for implementing reverse DNS lookups, but other uses include such things as DNS-SD. |
SOA : start of authority record ( RFC 1035)
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. |
DS : Delegation signer ( RFC 4034)
The record used to identify the DNSSEC signing key of a delegated zone |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
NS : name server record ( RFC 1035)
Delegates a DNS zone to use the given authoritative name servers |
DNSKEY : DNS Key record ( RFC 4034)
The key record used in DNSSEC. Uses the same format as the KEY record. |
DLV : DNSSEC Lookaside Validation record ( RFC 4431)
For publishing DNSSEC trust anchors outside of the DNS delegation chain. Uses the same format as the DS record. RFC 5074 describes a way of using these records. |
|
TA : DNSSEC Trust Authorities (None)
Part of a deployment proposal for DNSSEC without a signed DNS root. See the IANA database and Weiler Spec] for details. Uses the same format as the DS record.
|
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
MX : mail exchange record ( RFC 1035)
Maps a domain name to a list of mail exchange servers for that domain |
AFSDB : AFS database record ( RFC 1183)
Location of database servers of an AFS cell. This record is commonly used by AFS clients to contact AFS cells outside their local domain. A subtype of this record is used by the obsolete DCE/DFS file system. |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
