## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3075, "days_push": 996, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A shell script that benchmarks the latency of popular public DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, etc.) from your machine. It runs repeated dig queries and reports per-resolver average response times.

## Use cases
- compare dns resolver latency from my location
- find the fastest dns server for my network
- benchmark cloudflare vs google dns performance
- test dns response times from the command line
- measure which public dns resolver is quickest

## When to choose
- you want a quick, dependency-light shell script to compare public DNS resolver latency
- you're on Linux or macOS and have dig and bc available

## When to avoid
- you need DNSSEC validation, filtering, or correctness testing rather than latency
- you want a GUI or cross-platform Windows-native tool
- you need continuous monitoring rather than a one-off benchmark

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: benchmarking, networking, cli
- domain: networking, developer-tools, performance
- platform: cli
- tags: dns, shell-script, latency-testing, dns-resolvers, benchmark, command-line, linux, macos
