DS : Delegation signer ( RFC 4034)
The record used to identify the DNSSEC signing key of a delegated zone |
HIP : Host Identity Protocol ( RFC 5205)
Method of separating the end-point identifier and locator roles of IP addresses. |
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. |
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. |
AXFR : Full Zone Transfer ( RFC 1035)
Transfer entire zone file from the master name server to secondary name servers. |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
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. |
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. |
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. |
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 |
MX : mail exchange record ( RFC 1035)
Maps a domain name to a list of mail exchange servers for that domain |
DHCID : DHCP identifier ( RFC 4701)
Used in conjunction with the FQDN option to DHCP |
NSEC3PARAM : NSEC3 parameters ( RFC 5155)
Parameter record for use with NSEC3 |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
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. |
IXFR : Incremental Zone Transfer ( RFC 1995)
Requests a zone transfer of the given zone but only differences from a previous serial number. This request may be ignored and a full (AXFR) sent in response if the authoritative server is unable to fulfill the request due to configuration or lack of required deltas. |
