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. |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
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. |
LOC : Location record ( RFC 1876)
Specifies a geographical location associated with a domain name |
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. |
HIP : Host Identity Protocol ( RFC 5205)
Method of separating the end-point identifier and locator roles of IP addresses. |
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. |
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. |
|
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.
|
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. |
RRSIG : DNSSEC signature ( RFC 4034)
Signature for a DNSSEC-secured record set. Uses the same format as the SIG 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. |
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. |
OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
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. |
IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
DHCID : DHCP identifier ( RFC 4701)
Used in conjunction with the FQDN option to DHCP |
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. |
