Setting up secure, private dns cache for local network

See https://calomel.org/unbound_dns.html - specifically recursive, authoritative, validating dns over tls cache using 9.9.9.9 and 1.1.1.1

Setup

  • Unifi usg with unifi controller running on a raspi with fixed ip
  • unifi usg serves dhcp and hostnames for dhcp devices, upstreams to local dns cache
  • local dns cache upstreams over tls, and validates with dnssec
