In the current registry for Extended DNS Error Codes (RFC 8914), there are codes that may be interesting to add:
* One to say that the response was deliberately minimal (RFC 8482) * One to say that the response comes from a local root (RFC 8806) * One to say that the response has been tailored because of ECS (RFC 7871) [the most useful, IMHO] I am thinking about asking for a registration. Policy for this registry is "first come, first served". Before I start sending email to IANA, I ask your advice. Is it a good idea? Will the authors of resolver / authoritative software use it? _______________________________________________ DNSOP mailing list -- dnsop@ietf.org To unsubscribe send an email to dnsop-le...@ietf.org
