Detailed description | ![]() |
Network calculator for subnet mask and other classless (CIDR) network information.
Given an IP address and CIDR network size, it calculates the network information and provides all-in-one aggregated reports.
* IP address * Network size * Subnet mask * Network portion * Host portion * Number of IP addresses in the network * Number of addressable hosts in the network * IP address range * Broadcast address * Min and max host * All IP addresses * Is an IP address in the subnet * IPv4 ARPA domain
Provides each data in dotted quads, hexadecimal, and binary formats, as well as array of quads.
* Associative array * JSON * String * Printed to STDOUT
* JsonSerializable
Add the library to your composer.json
file in your project:
{
"require": {
"markrogoyski/ipv4-subnet-calculator": "4.*"
}
}
Use composer to install the library:
$ php composer.phar install
Composer will install IPv4 Subnet Calculator inside your vendor folder. 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.*
* PHP 7.2
Note: For PHP 5.5 through 7.1, use v3.0 (markrogoyski/ipv4-subnet-calculator:3.*
)
