MX : mail exchange record ( RFC 1035)
Maps a domain name to a list of mail exchange servers for that domain |
KEY : Key record ( RFC 4034)

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. |
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. |
RRSIG : DNSSEC signature ( RFC 4034)
Signature for a DNSSEC-secured record set. Uses the same format as the SIG record. |
NS : name server record ( RFC 1035)
Delegates a DNS zone to use the given authoritative name servers |
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. |
DLV : DNSSEC Lookaside Validation record ( RFC 4431)

Specifies a geographical location associated with a domain name |
AFSDB : AFS database record ( RFC 1183)

IPSECKEY : IPSEC Key ( RFC 4025)
Key record that can be used with IPSEC |
HIP : Host Identity Protocol ( RFC 5205)
Method of separating the end-point identifier and locator roles of IP addresses. |
SPF : SPF record ( RFC 4408)

OPT : Option ( RFC 2671)
This is a 'pseudo DNS record type' needed to support EDNS |
CERT : Certificate record ( RFC 4398)
Stores PKIX, SPKI, PGP, etc. |
DNSKEY : DNS Key record ( RFC 4034)
The key record used in DNSSEC. Uses the same format as the KEY record. |
AXFR : Full Zone Transfer ( RFC 1035)
