[![License](https://poser.pugx.org/markrogoyski/math-php/license)](https://packagist.org/packages/markrogoyski/ipv4-subnet-calculator-php)

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:

```javascript
{
  "require": {
      "markrogoyski/ipv4-subnet-calculator": "4.*"
  }
}
```

Use [composer](http://getcomposer.org) to install the library:

```bash
$ 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.

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

### Various Network Information
```php
$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
```php
$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
```php
$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
```php
$network        = $sub->getNetworkPortion();        // 192.168.112.0
$networkQuads   = $sub->getNetworkPortionQuads();   // [192, 168, 112, 0]
$networkHex     = $sub->getNetworkPortionHex();     // C0A87000
$networkBinary  = $sub->getNetworkPortionBinary();  // 11000000101010000111000000000000
$networkInteger = $sub->getNetworkPortionInteger(); // 3232264192
```

### Host Portion
```php
$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
```php
$minHost        = $sub->getMinHost();        // 192.168.112.1

```

### All IP Addresses
```php
foreach ($sub->getAllIPAddresses() as $ipAddress) {
    echo $ipAddress;
}

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

### Is IP Address in Subnet
```php
$boolTrue  = $sub->isIPAddressInSubnet('192.168.112.5');
$boolFalse = $sub->isIPAddressInSubnet('192.168.111.5');
```

### Reverse DNS Lookup (ARPA Domain)
