DS : Delegation signer ( RFC 4034)
The record used to identify the DNSSEC signing key of a delegated zone |
HIP : Host Identity Protocol ( RFC 5205)
Method of separating the end-point identifier and locator roles of IP addresses. |
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. |
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. |
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. |
NS : name server record ( RFC 1035)
Delegates a DNS zone to use the given authoritative name servers |
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. |
* : All cached records ( RFC 1035)
Returns all records of all types known to the name server. If the name server does not have any information on the name, the request will be forwarded on. The records returned may not be complete. For example, if there is both an A and an MX for a name, but the name server has only the A record cached, only the A record will be returned. |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
SPF : SPF record ( RFC 4408)
Specified as part of the SPF protocol, as an alternative to storing SPF data in TXT records. Uses the same format as the TXT record. |
OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
MX : mail exchange record ( RFC 1035)
Maps a domain name to a list of mail exchange servers for that domain |
CNAME : Canonical name record ( RFC 1035)
Alias of one name to another: the DNS lookup will continue by retrying the lookup with the new name. |
SRV : Service locator ( RFC 2782)
Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. |
NSEC3PARAM : NSEC3 parameters ( RFC 5155)
Parameter record for use with NSEC3 |
DHCID : DHCP identifier ( RFC 4701)
Used in conjunction with the FQDN option to DHCP |
|
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.
|
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. |
