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. |
NSEC3 : NSEC record version 3 ( RFC 5155)
An extension to DNSSEC that allows proof of nonexistence for a name without permitting zonewalking |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
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. |
|
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.
|
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. |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
AXFR : Full Zone Transfer ( RFC 1035)
Transfer entire zone file from the master name server to secondary name servers. |
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. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain 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. |
SRV : Service locator ( RFC 2782)
Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. |
DNSKEY : DNS Key record ( RFC 4034)
The key record used in DNSSEC. Uses the same format as the KEY record. |
NSEC3PARAM : NSEC3 parameters ( RFC 5155)
Parameter record for use with NSEC3 |
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. |
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. |
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. |
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. |
