Then you can add the following to your .php files to the use library with Autoloading. ``` require_once(__DIR__ . '/vendor/autoload.php'); ``` Alternatively, use composer on the command line to require and install IPv4 SubnetCalculator: ``` $ php composer.phar require markrogoyski/ipv4-subnet-calculator:4.* ``` ### Minimum Requirements [](#minimum-requirements) - PHP 7.2 Note: For PHP 5.5 through 7.1, use v3.0 (`markrogoyski/ipv4-subnet-calculator:3.*`) Usage ----- [](#usage) ### Create New SubnetCalculator [](#create-new-subnetcalculator) ``` // For network 192.168.112.203/23 $sub = new IPv4\SubnetCalculator('192.168.112.203', 23);
