 DownloadIPv4 Subnet Calculator (PHP)
Network calculator for subnet mask and other classless (CIDR) network information.
Features
Given an IP address and CIDR network size, it calculates the network information and provides all-in-one aggregated reports.
Calculations
* 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.
Aggregated Network Calculation Reports
* Associative array
* JSON
* String
* Printed to STDOUT
Standard Interfaces
* JsonSerializable
Setup
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.*
Minimum Requirements
* PHP 7.2
Note: For PHP 5.5 through 7.1, use v3.0 (markrogoyski/ipv4-subnet-calculator:3.*)
Usage
Create New SubnetCalculator

$networkInteger = $sub->getNetworkPortionInteger(); // 3232264192
Host Portion
$host = $sub->getHostPortion(); // 0.0.0.203
$hostQuads = $sub->getHostPortionQuads(); // [0, 0, 0, 203]
$hostHex = $sub->getHostPortionHex(); // 000000CB
$hostBinary = $sub->getHostPortionBinary(); // 00000000000000000000000011001011
$hostInteger = $sub->getHostPortionInteger(); // 203
Min and Max Host
$minHost = $sub->getMinHost(); // 192.168.112.1
$minHostQuads = $sub->getMinHostQuads(); // [192, 168, 112, 1]
$minHostHex = $sub->getMinHostHex(); // C0A87001
$minHostBinary = $sub->getMinHostBinary(); // 11000000101010000111000000000001
$minHostInteger = $sub->getMinHostInteger(); // 3232264193
$maxHost = $sub->getMaxHost(); // 192.168.113.254
$maxHostQuads = $sub->getMaxHostQuads(); // [192, 168, 113, 254]
$maxHostHex = $sub->getMaxHostHex(); // C0A871FE
$maxHostBinary = $sub->getMaxHostBinary(); // 11000000101010000111000111111110
$maxHostInteger = $sub->getMaxHostInteger(); // 3232264702
All IP Addresses
foreach ($sub->getAllIPAddresses() as $ipAddress) {
