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. |
* : 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. |
|
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.
|
SRV : Service locator ( RFC 2782)
Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. |
AXFR : Full Zone Transfer ( RFC 1035)
Transfer entire zone file from the master name server to secondary name servers. |
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. |
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. |
DHCID : DHCP identifier ( RFC 4701)
Used in conjunction with the FQDN option to DHCP |
RRSIG : DNSSEC signature ( RFC 4034)
Signature for a DNSSEC-secured record set. Uses the same format as the SIG record. |
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. |
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. |
DNSKEY : DNS Key record ( RFC 4034)
The key record used in DNSSEC. Uses the same format as the KEY record. |
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. |
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. |
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. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
