history

Project history and usage

asnmap is ProjectDiscovery's Go CLI and library for mapping autonomous system, organization, domain, and IP inputs to network ranges. It fits the ProjectDiscovery style of small composable reconnaissance tools with stdin/stdout support and automation-friendly JSON and CSV output.

Project history

The official README presents asnmap as both a command-line tool and Go library built on top of the ASNMap API. It acknowledges Frank Denis for maintaining the free IPtoASN database, making the project a packaged interface around ASN/CIDR lookup data useful in security and network inventory workflows.

Adoption history

The Homebrew input records asnmap in Homebrew, dnf, and Nix. Upstream installation also documents `go install github.com/projectdiscovery/asnmap/cmd/asnmap@latest` and precompiled binaries from the GitHub releases page, which is typical for ProjectDiscovery tools distributed both through Go and OS package managers.

How it is used

asnmap accepts ASN, IP, domain, organization, file, and stdin input. Common package-manager usage is simple shell composition: query an organization or AS number, emit CIDR ranges, and pipe them into other recon tools.

The README explicitly shows pipelines into ProjectDiscovery tools such as `tlsx`, `dnsx`, `naabu`, `httpx`, and `nuclei`, and it documents JSON and CSV output for post-processing.

Why package nerds care

For package nerds, asnmap is notable less as a standalone network database and more as a glue utility: it converts high-level organization or ASN targets into CIDR material that the rest of a CLI security toolchain can consume.

The tool's API-token support also marks a shift seen in modern recon CLIs: a packaged open-source binary can still depend on a hosted platform token for full operation.

Timeline

2022: README examples show v0.0.1-era output and timestamped JSON examples for ASN/CIDR lookup.
Current README: Installation requires Go 1.21, supports precompiled releases, and documents ProjectDiscovery Cloud API token configuration.
