README

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

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": "3.*"
  }
}

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:3.*

Minimum Requirements

PHP 5.5

Usage

// For network 192.168.112.203/23
$sub = new IPv4\SubnetCalculator('192.168.112.203', 23);

Various Network Information

$addressable_host_range = $sub->getAddressableHostRange();   // [192.168.112.1, 192.168.113.254]
$network_size           = $sub->getNetworkSize();            // 23
$broadcast_address      = $sub->getBroadcastAddress();       // 192.168.113.255

IP Address

$ip_address        = $sub->getIPAddress();       // 192.168.112.203

$ip_address_hex    = $sub->getIPAddressHex();    // C0A870CB
$ip_address_binary = $sub->getIPAddressBinary(); // 11000000101010000111000011001011

Subnet Mask

$subnet_mask        = $sub->getSubnetMask();       // 255.255.254.0

$subnet_mask_hex    = $sub->getSubnetMaskHex();    // FFFFFE00
$subnet_mask_binary = $sub->getSubnetMaskBinary(); // 11111111111111111111111000000000

Network Portion

$network        = $sub->getNetworkPortion();       // 192.168.112.0
$network_quads  = $sub->getNetworkPortionQuads();  // [192, 168, 112, 0]
$network_hex    = $sub->getNetworkPortionHex();    // C0A87000
$network_binary = $sub->getNetworkPortionBinary(); // 11000000101010000111000000000000

Host Portion

$host        = $sub->getHostPortion();       // 0.0.0.203
$host_quads  = $sub->getHostPortionQuads();  // [0, 0, 0, 203]
$host_hex    = $sub->getHostPortionHex();    // 000000CB
$host_binary = $sub->getHostPortionBinary(); // 00000000000000000000000011001011

Min and Max Host

$min_host        = $sub->getMinHost();       // 192.168.112.1
$min_host_quads  = $sub->getMinHostQuads();  // [192, 168, 112, 1]
$min_host_hex    = $sub->getMinHostHex();    // C0A87001
