The package contains various network utilities useful for:

- getting info about IP address;
- checking if IP is in a certain range;
- expanding IPv6;
- converting IP to bits representation;
- checking DNS record availability.

## Requirements

- PHP 7.4 - 8.5.

## Installation

The package could be installed with [Composer](https://getcomposer.org):

```shell
composer require yiisoft/network-utilities
```

## General usage

### `IpHelper`

```php
use Yiisoft\NetworkUtilities\IpHelper;

// Check IP version.
$version = IpHelper::getIpVersion('192.168.1.1');
if ($version === IpHelper::IPV4) {
    // ...
}

// Check if IP is in a certain range.
if (!IpHelper::inRange('192.168.1.21/32', '192.168.1.0/24')) {
    throw new \RuntimeException('Access denied!');
}

// Expand IP v6.
echo IpHelper::expandIPv6('2001:db8::1');

// Convert IP to bits representation.
echo IpHelper::ip2bin('192.168.1.1');

// Get bits from CIDR Notation.
echo IpHelper::getCidrBits('192.168.1.21/32');
```

### `DnsHelper`

```php
use Yiisoft\NetworkUtilities\DnsHelper;

// Check DNS record availability.
if (!DnsHelper::existsA('yiiframework.com')) {
  // Record not found.
}
```

### `IpRanges`

```php
use Yiisoft\NetworkUtilities\IpRanges;

$ipRanges = new IpRanges(
    [
        '10.0.1.0/24',
        '2001:db0:1:2::/64',
        IpRanges::LOCALHOST,
        'myNetworkEu',
        '!' . IpRanges::ANY,
    ],
    [
        'myNetworkEu' => ['1.2.3.4/10', '5.6.7.8'],
    ],
);

$ipRanges->isAllowed('10.0.1.28/28'); // true
$ipRanges->isAllowed('1.2.3.4'); // true
$ipRanges->isAllowed('192.168.0.1'); // false
```
