[DNSOP] RFC7477 typo?

Thus far, I don't think we've heard from any browser vendors who believe that it would be prudent and worthwhile to display server-generated error pages of this kind to ordinary end-users on their personal devices. Absent that support, I think it would not be sensible for us to try to develop s

Tim, The EDE error codes cover that use case already, by allowing the browser to generate that error page, and without requiring the DNS filter to run an HTTP server at all. --Ben Schwartz From: DNSOP on behalf of Tim Wicinski Sent: Thursday, November 9, 2023

I think we're conflating how you learn what endpoint to send NOTIFY to, with the protocol extensions or changes to make it legal/normal to do NOTIFY for this purpose. I don't personally think the whole "but how do I know where to do it" is as important as some of you seem to think it is. But, havi
