IPv4 Subnet Calculator (PHP)

Network calculator for subnet mask and other classless (CIDR) network information.

Coverage Status License

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

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

Various Network Information

$numbeIpAddresses     = $sub->getNumberIPAddresses();      // 512
$numberHosts          = $sub->getNumberAddressableHosts(); // 510
$addressRange         = $sub->getIPAddressRange();         // [192.168.112.0, 192.168.113.255]
$addressableHostRange = $sub->getAddressableHostRange();   // [192.168.112.1, 192.168.113.254]
$networkSize          = $sub->getNetworkSize();            // 23
$broadcastAddress     = $sub->getBroadcastAddress();       // 192.168.113.255

IP Address

$ipAddress        = $sub->getIPAddress();        // 192.168.112.203
$ipAddressQuads   = $sub->getIPAddressQuads();   // [192, 168, 112, 203]
$ipAddressHex     = $sub->getIPAddressHex();     // C0A870CB
$ipAddressBinary  = $sub->getIPAddressBinary();  // 11000000101010000111000011001011
$ipAddressInteger = $sub->getIPAddressInteger(); // 3232264395;

Subnet Mask

$subnetMask        = $sub->getSubnetMask();        // 255.255.254.0
$subnetMaskQuads   = $sub->getSubnetMaskQuads();   // [255, 255, 254, 0]
$subnetMaskHex     = $sub->getSubnetMaskHex();     // FFFFFE00
$subnetMaskBinary  = $sub->getSubnetMaskBinary();  // 11111111111111111111111000000000
$subnetMaskInteger = $sub->getSubnetMaskInteger(); // 4294966784

Network Portion

$network        = $sub->getNetworkPortion();        // 192.168.112.0

$networkBinary  = $sub->getNetworkPortionBinary();  // 11000000101010000111000000000000
$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

$maxHostInteger = $sub->getMaxHostInteger(); // 3232264702

All IP Addresses

foreach ($sub->getAllIPAddresses() as $ipAddress) {
    echo $ipAddress;
}

foreach ($sub->getAllHostIPAddresses() as $hostAddress) {
    echo $hostAddress;
}

Is IP Address in Subnet

$boolTrue  = $sub->isIPAddressInSubnet('192.168.112.5');
$boolFalse = $sub->isIPAddressInSubnet('192.168.111.5');

Reverse DNS Lookup (ARPA Domain)

$ipv4ArpaDomain = $sub->getIPv4ArpaDomain(); // 203.112.168.192.in-addr.arpa
