The project page lists version 1.0 in 2004, version 1.1 in 2013, and version 1.2 in 2014. It also records a license change: version 1.0 under the GPL, and version 1.1 and later under the Beerware license. ### 採用の歴史 The package is obscure but durable: its value is the classic Unix shape of a tiny calculator binary plus a companion matcher, easy to build with make and gcc and easy for package managers to wrap. ### 使われ方 Users run `ipinfo` with an address and optional mask or prefix to print network-derived values, or use flags to select a specific output such as netmask, prefix, broadcast, host count, or host range. `ipmatch` handles the related membership test: whether an address belongs to a subnet, is the network address, or is the broadcast address. ### パッケージ好きにとっての重要性 This is the non-API `ipinfo` package, not IPinfo.io's `ipinfo-cli`. The distinction matters because both expose network-oriented commands, but Kyberdigi ipinfo is a local subnet calculator whose Homebrew executable is `ipmatch` in the supplied metadata. Its significance is mostly historical and practical: a tiny pre-cloud networking helper with a Beerware license and a name that now collides with a much larger IP intelligence brand. ### タイムライン - 2004: Version 1.0 released. - 2013: Version 1.1 released. - 2014: Version 1.2 released. ### Related projects - ipcalc and sipcalc occupy similar subnet-calculation territory. - IPinfo CLI is unrelated despite the similar package name in some package managers. ### ソース - ## セキュリティノート broad file, network, media, or database tool signal. - **Geiger リスク:** blue / 中 - broad file, network, media, or database tool signal ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** ipinfo - **Version Scheme:** 0 - **Revision:** 0 - **Conflicts With:** ipinfo-cli - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Nix - ipinfo: normalized package name match | nixpkgs package indexes: pkgs/by-name/ip/ipinfo/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - winget - ipinfo.ipinfo: normalized package name match | Windows Package Manager source index: ipinfo.ipinfo from https://cdn.winget.microsoft.com/cache/source.msix ## 関連リンク - [Secret-risk packages](https://pkg.so/ja/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [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. - [ipinfo-cli](https://pkg.so/ja/brew/ipinfo-cli/) - Package name indicates the same formula family. - [ipcalc](https://pkg.so/ja/brew/ipcalc/) - Shares pkgdb curated category or tags: cli, ip-address, network-calculator, networking, subnet. - [mapcidr](https://pkg.so/ja/brew/mapcidr/) - Shares pkgdb curated category or tags: cidr, cli, networking, subnet. - [netaddr](https://pkg.so/ja/brew/netaddr/) - Shares pkgdb curated category or tags: cidr, cli, ip-address, networking. - [range2cidr](https://pkg.so/ja/brew/range2cidr/) - Shares pkgdb curated category or tags: cidr, cli, ip-address, networking. - [cidrmerge](https://pkg.so/ja/brew/cidrmerge/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [cidr](https://pkg.so/ja/brew/cidr/) - 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. ## Combined YAML source View the package source record on GitHub.
