[Wiki](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) Installing CIDR Library ----------------------- [](#installing-cidr-library) The recommended way to install CIDR Library is through [Composer](http://getcomposer.org). ``` # Install Composer curl -sS https://getcomposer.org/installer | php ``` Next, run the Composer command to install the latest stable version of CIDR Library: ``` composer require lionser/cidr ``` After installing, you need to require Composer's autoloader: ``` require 'vendor/autoload.php'; ``` You can then later update CIDR Library using composer: ``` composer update ``` Usage example: ``` $netmaskDetectror = new \Lionser\Detector\NetmaskDetector(); $parser = new \Lionser\Parser\CIDRRangeParser($netmaskDetectror); $start = new \Lionser\ValueObject\IP\IPv4('1.0.0.0'); $end = new \Lionser\ValueObject\IP\IPv4('1.0.0.255'); $range = new \Lionser\ValueObject\IP\Range($start, $end); /** @var $cidrs \Lionser\ValueObject\CIDR[] */ $cidrs = $parser->parseRange($range); # Or facade usage /** @var $cidrs \Lionser\ValueObject\CIDR[] */ $cidrs = \Lionser\Parser\CIDRParserFacade::parse('1.0.0.0', '1.0.0.255'); foreach($cidrs as $cidr) { echo $cidr; # '1.0.0.0\24' } ``` ### Health Score 35 — LowBetter than 77% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity22 Limited adoption so far Community9 Small or concentrated contributor base Maturity73 Established project with proven stability Bus Factor1 Top contributor holds 71.4% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~114 days Recently: every ~257 days Total 10 Last Release 1388d ago Major Versions 1.0.8 → 2.0.02022-09-14 PHP version history (2 changes)1.0.0PHP ^7.1 2.0.0PHP ^8.1 ### Community Maintainers ![](https://www.gravatar.com/avatar/9616b9b8bec17f82f0d19e4333bffc690e55238763e6706c529f494186c1b989?d=identicon)[Lionser](/maintainers/Lionser) --- Top Contributors [![lionser](https://avatars.githubusercontent.com/u/26322780?v=4)](https://github.com/lionser "lionser (20 commits)")[![Formmeras](https://avatars.githubusercontent.com/u/124682454?v=4)](https://github.com/Formmeras "Formmeras (8 commits)") --- Tags parserIPcidrip range ### Code Quality TestsPHPUnit Code StylePHP\_CodeSniffer ### Embed Badge ![Health badge](/badges/lionser-cidr/health.svg) ``` [![Health](https://phpackages.com/badges/lionser-cidr/health.svg)](https://phpackages.com/packages/lionser-cidr) ``` ### Alternatives [nikic/php-parser A PHP parser written in PHP 17.4k954.1M2.5k](/packages/nikic-php-parser)[doctrine/lexer PHP Doctrine Lexer parser library that can be used in Top-Down, Recursive Descent Parsers. 11.2k959.8M160](/packages/doctrine-lexer)[erusev/parsedown Parser for Markdown. 15.1k156.8M867](/packages/erusev-parsedown)[league/commonmark Highly-extensible PHP Markdown parser which fully supports the CommonMark spec and GitHub-Flavored Markdown (GFM) 3.0k437.5M1.0k](/packages/league-commonmark)[masterminds/html5 An HTML5 parser and serializer. 1.8k269.7M320](/packages/masterminds-html5)[sabberworm/php-css-parser Parser for CSS Files written in PHP 1.8k211.0M75](/packages/sabberworm-php-css-parser) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
