The README defines the tool around CIDR explanation, address containment, address counting, overlap checks, and division into smaller networks. ### 採用の歴史 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. ### 使われ方 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. ### パッケージ好きにとっての重要性 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. ### タイムライン - 2022: Public GitHub repository and v0.1.0 release. - 2023: v1.x releases established the CLI line. - 2024: v2.0.0 released. - 2025: v2.3.0 released. ### Related projects - Related tools in this batch include cidr2range, cidrmerge, and IPinfo CLI's IP-range helper binaries. ### ソース - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cidr - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 他のパッケージマネージャ記録 - Debian apt - cidr - 2.2.0-2+b9: normalized package name match | Debian stable package indexes: cidr from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Simplifies IPv4/IPv6 CIDR network prefix management | https://github.com/bschaatsbergen/cidr - MacPorts - cidr: normalized package name match | MacPorts ports tree: net/cidr/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 関連リンク - [Source-control packages](https://pkg.so/ja/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/ja/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/ja/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://pkg.so/ja/brew-utility-packages/) - Matched Homebrew package provider. - [go](https://pkg.so/ja/brew/go/) - Build dependency declared by Homebrew. - [prips](https://pkg.so/ja/brew/prips/) - Shares pkgdb curated category or tags: cidr, cli, ip-addresses, networking. - [cidrmerge](https://pkg.so/ja/brew/cidrmerge/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [grepcidr](https://pkg.so/ja/brew/grepcidr/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [mapcidr](https://pkg.so/ja/brew/mapcidr/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [cidr2range](https://pkg.so/ja/brew/cidr2range/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [c-ares](https://pkg.so/ja/brew/c-ares/) - Shares pkgdb curated category or tags: cli, networking. - [unbound](https://pkg.so/ja/brew/unbound/) - Shares pkgdb curated category or tags: cli, networking. - [telnet](https://pkg.so/ja/brew/telnet/) - Shares pkgdb curated category or tags: cli, networking. - [asnmap](https://pkg.so/ja/brew/asnmap/) - Local package facts share a topical domain.
