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. |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
AXFR : Full Zone Transfer ( RFC 1035)
Transfer entire zone file from the master name server to secondary name servers. |
SRV : Service locator ( RFC 2782)
Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. |
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. |
|
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.
|
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. |
DNAME : delegation name ( RFC 2672)
DNAME will delegate an entire portion of the DNS tree under a new name. In contrast, the CNAME record creates an alias of a single name. Like the CNAME record, the DNS lookup will continue by retrying the lookup with the new name. |
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. |
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. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
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. |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
SSHFP : SSH Public Key Fingerprint ( RFC 4255)
Resource record for publishing SSH public host key fingerprints in the DNS System, in order to aid in verifying the authenticity of the host. |
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. |
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 |
