## プロジェクトの歴史と使われ方

cidr2range is one of the standalone helper binaries shipped from IPinfo's official CLI repository; it converts CIDR prefixes into IP ranges.

### プロジェクトの歴史

IPinfo's CLI repository was created in October 2020 for the company's official command-line interface. Its README lists cidr2range among the separately shipped subcommand binaries, alongside cidr2ip, range2cidr, range2ip, splitcidr, prips, matchip, and other IP helpers.

### 採用の歴史

The upstream README says the IPinfo CLI suite is distributed through Homebrew, Ubuntu PPA, Debian or Ubuntu install scripts and debs, FreeBSD ports, Arch AUR, Scoop, Docker, Go install, GitHub release artifacts, and source builds. The batch input records cidr2range itself as a Homebrew formula.

### 使われ方

As a standalone binary, cidr2range handles the narrow conversion from CIDR notation to start-end IP ranges. It is part of a family of small IP list, range, and CIDR utilities distributed with IPinfo CLI releases.

### パッケージ好きにとっての重要性

cidr2range is useful because package managers can expose a tiny, script-friendly IP conversion tool without requiring users to remember a larger CLI subcommand. It is also an example of one upstream Go repository producing several separately packaged command binaries.

### タイムライン

- 2020: IPinfo CLI repository created.
- 2021: cidr2range-1.2.0 release published.
- 2020s: IPinfo CLI README documents cidr2range as a separately shipped subcommand binary.

### Related projects

- Related IPinfo helper binaries include cidr2ip, range2cidr, range2ip, splitcidr, prips, matchip, grepip, randip, and mmdb.
