Extended DNS Errors
RFC 8914, “Extended DNS Errors”, is a Proposed Standard document published in October 2020 by W. Kumari, E. Hunt, R. Arends, W. Hardaker, D. Lawrence. The canonical text is published by the RFC Editor.
Abstract
This document defines an extensible method to return additional information about the cause of DNS errors. Though created primarily to extend SERVFAIL to provide additional information about the cause of DNS and DNSSEC failures, the Extended DNS Errors option defined in this document allows all response types to contain extended error information. Extended DNS Error information does not change the processing of RCODEs.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
