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. |
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. |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
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. |
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. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
RRSIG : DNSSEC signature ( RFC 4034)
Signature for a DNSSEC-secured record set. Uses the same format as the SIG record. |
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 |
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. |
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. |
DS : Delegation signer ( RFC 4034)
The record used to identify the DNSSEC signing key of a delegated zone |
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. |
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. |
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. |
* : 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. |
