KEY : Key record ( RFC 4034)

NSEC3PARAM : NSEC3 parameters ( RFC 5155)
Parameter record for use with NSEC3 |
DLV : DNSSEC Lookaside Validation record ( RFC 4431)
For publishing DNSSEC trust anchors outside of the DNS delegation chain. Uses the same format as the DS record. RFC 5074 describes a way of using these records. |
AXFR : Full Zone Transfer ( RFC 1035)

OPT : Option ( RFC 2671)

DNAME : delegation name ( RFC 2672)
