Networking projects

Networking currently centers on Pi-hole as an always-on DNS filtering service for a home network. It can run on Raspberry Pi 5, Zero 2 W, or Pi 400, but those hosts imply different roles: a Zero 2 W is a compact dedicated appliance, while a Pi 5 has headroom for additional services. Pi-hole changes how clients resolve domains; it does not block every advertisement, inspect encrypted page content, or replace a firewall. Give the server a stable address and configure router or client DNS deliberately, with a tested fallback and recovery path. Restrict administration to trusted users, maintain updates, and avoid exposing the dashboard or DNS service directly to the public internet.
