Blocky
Filter DNS requests on a local network with Blocky, a DNS proxy and ad blocker written in Go.

About Blocky
Blocky is a DNS proxy for a local network that filters DNS queries and forwards allowed queries to upstream resolvers. It blocks domains using external lists with allowlisting, per-client-group rules, regex support, and inspection of response CNAMEs and IP addresses.
It also handles custom DNS records, conditional forwarding, per-group upstream resolvers, caching with prefetching, and DNS over UDP, TCP, HTTPS, TLS, QUIC and HTTPS/3, with DNSSEC validation and query logging to CSV or SQL databases.
Key features

- Inspect response CNAMEs and IPs against block lists
- Forward conditionally and set upstream resolvers per group

- Uses freely configurable blocking lists with no hidden filtering
- Runs stateless without a database as a single binary or Docker image
