Supported record types:

NS
Name server record, delegates a DNS zone to use the given authoritative name servers.
NSEC
Next secure record, part of DNSSEC, used to prove a name does not exist.
PTR
Pointer to a canonical name. The most common use is for implementing reverse DNS lookups.
RRSIG
Signature for a DNSSEC-secured record set.

TXT
Text record, originally for arbitrary human-readable text in a DNS record. Since the early 1990s, however, this record more often carries machine-readable data.
