Re: [OPSAWG] [radext] [Add] 🔔 WG LC: RADIUS Extensions for Encrypted DNS

Hi Joe,

That’s because network services are isolated/segregated by adequate addressing schemes. I don’t expect that to change and see DNS service offered by operators be muxed with other customler-facing services they offer.

Cheers,
Med

Hi Mohamed,

I may well have missed some nuance in the discussion that came before, but I found this comment interesting:

This specification targets typical broadband services in which the use of ECH is not relevant. It does not make sense for ISPs to be hosting multiple domains on the same IP address as the encrypted DNS resolver.

Can you say why?

If an operator has invested in infrasructure designed to be able to handle TLS and HTTP at high volumes with high availability, does it not seem possible that they would seek to reuse that general TLS/HTTP infrastructure for multiple purposes? If ECH is relevant in other services carried over HTTPS, why is it definitively not relevant for this one?
