Introduction The [RFC1035] defines couple of old resource records that are not being used, and they are causing operational problems between implementations that support them and that don't supported them due DNS compression on the wire. This document deprecates such records to allow the implementations to drop the specific support for such records. 2. Deprecating MB, MG, MF, MINFO and WKS Resource Records The MB, MG, MF, MINFO, and WKS Resource Records aren't used in any existing standards, and this documents deprecates the usage. The DNS implementations compliant with this document MUST NOT implement MB, MG, MF, WKS, and MINFO Resource Records and treat them as a generic type effectively disabling the compression in those types. 3. IANA Considerations This documents updates the IANA registry "Domain Name System (DNS) Parameters" ([DNS-IANA]). Sury Expires September 23, 2018 [Page 2]

Security Considerations This document has not security considerations. 5. Operational Considerations The various status of implementation of MB, MG, MR, MINFO, and WKS records is already causing operational problems between DNS implementations that do implement aforementioned types and those who don't because of mandatory DNS compression on the wire. This document aims to rectify the situation by removing the support for all the DNS implementations. This should not cause any operational problems because the records aren't actually in use on the Internet. [COMMENT: Some data?] 6. Acknowledgements Peter van Dijk for poking me to write the draft.
