The type of the resource record.

This specifies the type of data in the RData field of the Resource Record

Variants

A

RFC 1035[1] IPv4 Address record

AAAA

RFC 3596[2] IPv6 address record

ANY

RFC 1035[1] All cached records, aka ANY

AXFR

RFC 1035[1] Authoritative Zone Transfer

CAA

RFC 6844 Certification Authority Authorization

CNAME

RFC 1035[1] Canonical name record

IXFR

RFC 1996 Incremental Zone Transfer

MX

RFC 1035[1] Mail exchange record

NS

RFC 1035[1] Name server record

NULL

RFC 1035[1] Null server record, for testing

OPT

RFC 6891 Option

PTR

RFC 1035[1] Pointer record

SOA

RFC 1035[1] and RFC 2308[9] Start of [a zone of] authority record

SRV

RFC 2782 Service locator

TLSA

RFC 6698 TLSA certificate association

TXT

RFC 1035[1] Text record

DNSSEC(DNSSECRecordType)

A DNSSEC- or SIG(0)- specific record type.

These types are in DNSSECRecordType to make them easy to disable when crypto functionality isn't needed.

Unknown(u16)

Unknown Record type, or unsupported

ZERO

This corresponds to a record type of 0, unspecified

Methods
