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. |
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. |
* : 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. |
DHCID : DHCP identifier ( RFC 4701)
Used in conjunction with the FQDN option to DHCP |
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. |
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. |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
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. |
RRSIG : DNSSEC signature ( RFC 4034)
Signature for a DNSSEC-secured record set. Uses the same format as the SIG record. |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
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. |
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. |
MX : mail exchange record ( RFC 1035)
Maps a domain name to a list of mail exchange servers for that domain |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain 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. |
DNSKEY : DNS Key record ( RFC 4034)
The key record used in DNSSEC. Uses the same format as the KEY record. |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
