Abstract:
DNS filtering is widely deployed for various reasons, including
network security. However, filtered DNS responses lack information
for end users to understand the reason for the filtering. Existing
mechanisms to provide explanatory details to end users cause harm
especially if the blocked DNS response is to an HTTPS server.
This document updates RFC 8914 by signaling client support for
structuring the EXTRA-TEXT field of the Extended DNS Error to provide
details on the DNS filtering. Such details can be parsed by the
client and displayed, logged, or used for other purposes.
