Encrypted DNS with DoH/DoT: Ending ISP Hijacking at Home

Cleartext DNS exposes every domain you visit and can be hijacked. Encrypted upstreams fix both at once.

Why encrypt DNS

AdGuard Home speaks DoH/DoT: paste upstream URLs; latency usually grows under 5 ms;
Split routing: low-latency upstream for local domains, encrypted general upstream for the rest;
Enforce it: point DHCP at the RK3588 and block outbound port 53 so devices can’t bypass.

If one app won’t connect, check its “Private DNS” setting — Android’s private DNS can conflict with local DoH.
