What is dns-good?

dns-good is a Go-based DNS domain checker that validates if domains are truly active, scoring them from 0-250 across four sources: popularity rankings, registration status via RDAP, NS delegation, and direct A/AAAA resolution. It maintains a SQLite repository tracking domain status (ACTIVE, INACTIVE, STALE, UNKNOWN) with timestamps, automatically marking entries stale for periodic rechecks. Users get CLI modes like one-shot `check` on input lists, daemon `run` for ongoing dns domain lookup, and `stats` summaries, plus txt exports of active domains for easy integration.

Why is it gaining traction?

It bypasses public resolver throttling with iterative DNS from root servers, spreading load while catching delegation issues early. Configurable trust thresholds let you tune for strict (all sources) or lenient (resolution alone) dns domain checks, and daemon mode keeps lists fresh without cron hacks. Output snapshots are atomic and self-describing, perfect for pipelines needing reliable dns domain name system intel.

Who should use this?

DevOps engineers monitoring dns domain name servers for outages or expirations in large fleets. Security teams curating active domain whitelists/blocklists for threat hunting. Network admins validating dns domains der wireguard gegenstelle or fritzbox setups before deployment.

Verdict

Grab it for targeted dns good validation—docs are thorough, config flexible, builds clean on Go 1.22+. Low 1.0% credibility and 11 stars signal early maturity, so test on your domains first before prod.
