## プロジェクトの歴史と使われ方

dnsx is ProjectDiscovery's fast DNS query and resolution CLI, built for reconnaissance pipelines and bulk probing rather than interactive DNS administration.

Its history is mainly the history of ProjectDiscovery standardizing bug-bounty and attack-surface tooling around composable Go CLIs that stream data through stdin and stdout.

### プロジェクトの歴史

The public release line starts with v1.0.0 in November 2020, and subsequent releases kept dnsx in the ProjectDiscovery toolkit alongside tools such as subfinder, httpx, naabu, nuclei, and shuffledns.

The documentation and README frame dnsx as a retryabledns-based toolkit for multiple DNS query types, custom resolvers, brute-force resolution, and wildcard handling.

### 採用の歴史

dnsx became part of the common ProjectDiscovery reconnaissance workflow: subdomain inputs from one tool can be resolved and filtered through dnsx, then passed onward to HTTP probing or vulnerability scanning tools.

Packaging in Homebrew, Fedora, Nix, and Kali reflects adoption by both developer workstations and security-testing distributions.

### 使われ方

dnsx is commonly used to resolve lists of domains, query specific DNS record types, use custom resolver pools, brute-force names, and remove wildcard DNS noise from large candidate sets.

Its stdin/stdout design makes it useful in shell pipelines and CI-style scanning jobs.

### パッケージ好きにとっての重要性

dnsx matters less as a novel DNS protocol implementation and more as a modern packaging example: a single static-ish Go CLI designed to be chained with a security-tool ecosystem.

The package shows how DNS utilities have moved from administrator-only troubleshooting toward high-volume reconnaissance and asset inventory workflows.

### タイムライン

- 2020: dnsx v1.0.0 was released as a ProjectDiscovery DNS toolkit.
- 2021-2023: v1.0.x and v1.1.x releases broadened the tool while it became a regular component of ProjectDiscovery reconnaissance pipelines.
- 2024: v1.2.0 and later releases continued the Go module and packaging lifecycle.
- 2025: v1.2.3 release activity shows the project still being maintained.

### Related projects

- ProjectDiscovery siblings include subfinder for subdomain discovery, httpx for HTTP probing, naabu for port scanning, nuclei for template-based scanning, and shuffledns for mass DNS resolution with wildcard filtering.
- dnsx is also related to retryabledns, the Go library it uses for resilient DNS probing.
