C++20 recursive DNS server — DoH upstream, LRU cache, rate limiting, Prometheus metrics, built from scratch to understand DNS

A local authoritative resolver lab for replaying caching, negative answers, delegation, and DNSSEC failure modes.

A from-scratch, zero-dependency DNS server + ad-blocker in Python: hand-parsed wire protocol, recursive-from-root resolution, TTL cache, blocklist filtering, and a live dashboard.

Unbound for Home Assistant: recursive, caching, DNSSEC-validating DNS resolver app (add-on) on 127.0.0.1:5335 – the private upstream for Pi-hole. Runs unprivileged on amd64 and aarch64, with automated Alpine package updates.

Recursive DNS resolver with authoritative zones, block list filtering, DoT and DoH, and a live control plane
