history

Project history and usage

subnetcalc is a compact IPv4/IPv6 subnet calculator. Its package-manager relevance is straightforward: network operators and developers want a tiny local CLI that can answer address, prefix, mask, and reverse-DNS questions without opening a web calculator.

Project history

The official project page and GitHub repository describe subnetcalc as an IPv4 and IPv6 subnet calculator. The upstream changelog records continuing maintenance through the 2.x series, including modernizations such as build-system updates, package metadata, and optional integrations.

Adoption history

The official README gives package-oriented installation examples, including Ubuntu/Debian and Fedora commands, and the Homebrew input records additional availability in Homebrew, Nix, and openSUSE-family package managers. That is the normal adoption pattern for a small network CLI: broad distro packaging rather than a large standalone ecosystem.

How it is used

Typical use is invoking `subnetcalc` with an address or network prefix to print derived subnet information. Because it has no documented per-user configuration or credential store, it behaves like a traditional Unix filter-style utility: install it, run it, and get deterministic text output.

Why package nerds care

Package nerds care about subnetcalc because it is the sort of low-dependency diagnostic binary that belongs in base images, operations laptops, and rescue toolkits. It overlaps with mental math, `ipcalc`-style tools, and shell snippets, but packaging it gives users a consistent implementation across systems.

Timeline

  • 2009: The upstream changelog records early subnetcalc development and Debian packaging work.
  • 2010: The changelog records FreeBSD ports work.
  • 2026: Official Git tags show active 2.7.x releases.

Related projects

  • Related package-manager neighbors include `ipcalc`, `sipcalc`, and other local subnet calculators, but subnetcalc's official positioning is specifically IPv4/IPv6 subnet calculation.
