General Discussion / DNS caches
« on: May 08, 2021, 04:05:58 pm »
Can someone explain where the best place to put a DNS cache is?
My dns goes:
AdGuard Home -> Unbound -> DNSCrypt-Proxy (all within OPNsense across localhost).
All three of these services have caching options.
I would have thought the best place would have been DNSCrypt, or is it worth having caches at each stage?
Or is it best at just Unbound since it can refresh the cache based on the ttl?
