***** Additional DNS Record Types
To facilitate signature validation, DNSSEC adds a few new DNS record types:
RRSIG - Contains a cryptographic signature
DNSKEY - Contains a public signing key
DS - Contains the hash of a DNSKEY record
NSEC and NSEC3 - For explicit denial-of-existence of a DNS record
CDNSKEY and CDS - For a child zone requesting updates to DS record(s) in the parent zone.
