Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host. |
TKEY : Transaction Key ( RFC 2930)
One way of providing a key to be used with TSIG |
NSEC3 : NSEC record version 3 ( RFC 5155)
An extension to DNSSEC that allows proof of nonexistence for a name without permitting zonewalking |
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. |
