DNS is heavily cached. What are the caching implications for encrypting DNS?

  It's only the traffic that is encrypted. It's still cached on the server and the client.

    I wish it was cached by Firefox. But it's not. I'm running a DoH setup at home, and from the logs, it looks like Firefox is NOT doing any caching of results it gets. At least my DNS server is caching the results though.

  It's only the point-to-point transports that are encrypted, not the queries or responses, that is, the queries and responses are encrypted in transit but would still be cached in the clear for any other queries to benefit from on the resolvers. The caches will work the same as they do today.

  Not much any more, with load balancers/geo routing/CDNs generating ephemeral host names, and everybody using very low TTLs.
