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.
|
MX : mail exchange record ( RFC 1035)
Maps a domain name to a list of mail exchange servers for that domain |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
NSEC3PARAM : NSEC3 parameters ( RFC 5155)
Parameter record for use with NSEC3 |
SRV : Service locator ( RFC 2782)
Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. |
RRSIG : DNSSEC signature ( RFC 4034)
Signature for a DNSSEC-secured record set. Uses the same format as the SIG record. |
* : 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. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
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. |
AXFR : Full Zone Transfer ( RFC 1035)
Transfer entire zone file from the master name server to secondary name servers. |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
DNSKEY : DNS Key record ( RFC 4034)
The key record used in DNSSEC. Uses the same format as the KEY 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. |
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. |
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. |
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. |
TSIG : Transaction Signature ( RFC 2845)
Record that supports one set of security mechanisms for DNS. Used to secure communication between DNS resolvers and Name servers, in contrast to DNSSEC, which secures the actual DNS records from the authoritative name server. |
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. |
