Frequently asked questions (FAQ)

AdGuard Home or Pi-hole?

AdGuard Home: one binary, built-in DoH/DoT, modern UI. Pi-hole: mature Gravity lists, often + unbound. Both block at DNS.

Open port 53 on a VPS?

Not as a public resolver – it will be abused. Limit to your IPs or VPN/Tailscale only.

Home or datacenter?

LAN box for all home devices. VPS as a DoH endpoint or Tailscale-only DNS.

RAM?

512 MB–1 GB for lists. Fine on a shared 4 GB VPS.
