Informational status, rather than being on the IETF standards-track. It has always had limited deployment, but is
1270:
Progress has rendered some of the originally defined record-types obsolete. Of the records listed at IANA, some have limited use, for various reasons. Some are marked obsolete in the list, some are for very obscure services, some are for older versions of services, and some have special notes saying
2034:
RFC 3755, §3. "DNSKEY will be the replacement for KEY, with the mnemonic indicating that these keys are not for application use, per RFC3445. RRSIG (Resource Record SIGnature) will replace SIG, and NSEC (Next SECure) will replace NXT. These new types completely replace the old types, except that
1168:
Returns all records of all types known to the name server. If the name server does not have any information on the name, the request will be forwarded on. 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
1395:
Record to describe well-known services supported by a host. Not used in practice. The current recommendation and practice is to determine whether a service is supported on an IP address by trying to connect to it. SMTP is even prohibited from using WKS records in MX processing.
1130:
Other types of records simply provide some types of information (for example, an HINFO record gives a description of the type of computer/OS a host uses), or others return data used in experimental features. The "type" field is also used in the protocol for various operations.
1233:
Requests a zone transfer of the given zone but only differences from a previous serial number. This request may be ignored and a full (AXFR) sent in response if the authoritative server is unable to fulfill the request due to configuration or lack of required deltas.
546:
Used only for SIG(0) (RFC 2931) and TKEY (RFC 2930). RFC 3445 eliminated their use for application keys and limited their use to DNSSEC. RFC 3755 designates DNSKEY as the replacement within DNSSEC. RFC 4025 designates IPSECKEY as the replacement for use with IPsec.
1345:
VRFY and EXPN commands. MR was to replace the "551 User Not Local" SMTP error. Later, RFC 2505 recommended that both VRFY and EXPN be disabled, making MB and MG unnecessary. They were classified as experimental by RFC 1035.
1005:. RFC 6698 defines "The TLSA DNS resource record is used to associate a TLS server certificate or public key with the domain name where the record is found, thus forming a 'TLSA certificate association'".
1471:
Part of the first version of DNSSEC (RFC 2065). NXT was obsoleted by DNSSEC updates (RFC 3755). At the same time, the domain of applicability for KEY and SIG was also limited to not include DNSSEC use.
1308:
Mail destination (MD) and mail forwarder (MF) records; MAILA is not an actual record type, but a query type which returns MF and/or MD records. RFC 973 replaced these records with the MX record.
1525:
RP may be used for certain human-readable information regarding a different contact point for a specific host, subnet, or other domain level label separate than that used in the SOA record.
374:
Alias for a name and all its subnames, unlike CNAME, which is an alias for only the exact name. Like a CNAME record, the DNS lookup will continue by retrying the lookup with the new name.
1437:
Obsoleted by RFC 1035. RFC 883 defined "completion queries" (opcode 2 and maybe 3) which used this record. RFC 1035 later reassigned opcode 2 to be "status" and reserved opcode 3.
1509:
Record intended to provide information about host CPU type and operating system. It was intended to allow protocols to optimize processing when communicating with similar peers.

MB, MG, MR, and MINFO are records to publish subscriber mailing lists. MAILB is a query code which returns one of those records. The intent was for MB and MG to replace the
