OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
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. |
A : address record ( RFC 1035)
Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but also used for DNSBLs, storing subnet masks in RFC 1101, etc. |
HIP : Host Identity Protocol ( RFC 5205)
Method of separating the end-point identifier and locator roles of IP addresses. |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
NS : name server record ( RFC 1035)
Delegates a DNS zone to use the given authoritative name servers |
KEY : Key record ( RFC 4034)
Used only for TKEY (RFC 2930). Before RFC 3755 was published, this was also used for DNSSEC, but DNSSEC now uses DNSKEY. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
DS : Delegation signer ( RFC 4034)
The record used to identify the DNSSEC signing key of a delegated zone |
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. |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
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. |
IXFR : Incremental Zone Transfer ( RFC 1995)
Requests a zone transfer of the given zone but only differences from a previous serial number. This request may be ignored and a full (AXFR) sent in response if the authoritative server is unable to fulfill the request due to configuration or lack of required deltas. |
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. |
NSEC3 : NSEC record version 3 ( RFC 5155)
An extension to DNSSEC that allows proof of nonexistence for a name without permitting zonewalking |
|
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.
|
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. |
