## Projektgeschichte und Nutzung

cidr is a small Go command-line tool for inspecting, counting, checking, and subdividing IPv4 and IPv6 CIDR prefixes.

### Projektgeschichte

The GitHub repository was created in September 2022, and the first GitHub release followed that month. The README defines the tool around CIDR explanation, address containment, address counting, overlap checks, and division into smaller networks.

### Adoptionsgeschichte

The README documents Homebrew installation, Debian and Ubuntu packages for newer releases, and prebuilt binaries for Linux, macOS, and Windows. The batch input also records MacPorts packaging.

### Wie es verwendet wird

Typical commands include explaining a CIDR range, testing whether an address belongs to a range, counting addresses, checking whether two prefixes overlap, and dividing a prefix into distinct networks. The README examples cover both IPv4 and IPv6.

### Warum Paket-Nerds sich dafür interessieren

cidr is package-nerd useful because it packages common subnet arithmetic into a simple cross-platform CLI, replacing shell snippets or ad hoc web calculators in scripts, package tests, and network automation.

### Zeitleiste

- 2022: Public GitHub repository and v0.1.0 release.
- 2023: v1.x releases established the CLI line.
