• NS

  public static final DnsRecordType NS

  Name server record RFC 1035 Delegates a DNS zone to use the given authoritative name servers

  public static final DnsRecordType SOA

  Start of [a zone of] authority record RFC 1035 and RFC 2308 Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone.

  Mail exchange record RFC 1035 Maps a domain name to a list of message transfer agents for that domain.

• TXT

  public static final DnsRecordType TXT

  Text record RFC 1035 Originally for arbitrary human-readable text in a DNS record. Since the early 1990s, however, this record more often carries machine-readable data, such as specified by RFC 1464, opportunistic encryption, Sender Policy Framework, DKIM, DMARC DNS-SD, etc.

• RP

  public static final DnsRecordType RP

  Responsible person record RFC 1183 Information about the responsible person(s) for the domain. Usually an email address with the @ replaced by a .

• CERT

  public static final DnsRecordType CERT

  Certificate record RFC 4398 Stores PKIX, SPKI, PGP, etc.

• DNAME

  public static final DnsRecordType DNAME

  Delegation name record RFC 2672 DNAME creates an alias for a name and all its subnames, unlike CNAME, which aliases only the exact name in its label. Like the CNAME record, the DNS lookup will continue by retrying the lookup with the new name.

• OPT

  public static final DnsRecordType OPT

  Option record RFC 2671 This is a pseudo DNS record type needed to support EDNS.

• APL

  public static final DnsRecordType APL

  Address Prefix List record RFC 3123 Specify lists of address ranges, e.g. in CIDR format, for various address families. Experimental.

• SSHFP

  public static final DnsRecordType SSHFP

  SSH Public Key Fingerprint record RFC 4255 Resource record for publishing SSH public host key fingerprints in the DNS System, in order to aid in verifying the authenticity of the host. RFC 6594 defines ECC SSH keys and SHA-256 hashes. See the IANA SSHFP RR parameters registry for details.

  public static final DnsRecordType IXFR

  Incremental Zone Transfer record RFC 1996 Requests a zone transfer of the given zone but only differences from a previous serial number.

  Authoritative Zone Transfer record RFC 1035 Transfer entire zone file from the master name server to secondary name servers.

• ANY

  public static final DnsRecordType ANY

The records returned may not be complete. For example, if there is both an A and an MX for a name, but the name server has only the A record cached, only the A record will be returned. Sometimes referred to as ANY, for example in Windows nslookup and Wireshark.
