IPAddressRange Class Library [![tests](https://github.com/jsakamoto/ipaddressrange/actions/workflows/unit-tests.yml/badge.svg)](https://github.com/jsakamoto/ipaddressrange/actions/workflows/unit-tests.yml) [![NuGet Package](https://img.shields.io/nuget/v/IPAddressRange.svg)](https://www.nuget.org/packages/IPAddressRange/)

=============

This library allows you to parse range of IP address string such as "192.168.0.0/24" and "192.168.0.0/255.255.255.0" and "192.168.0.0-192.168.0.255", and can contains check.

This library supports both IPv4 and IPv6.

Example

-------

```csharp

using NetTools;

...

// rangeA.Begin is "192.168.0.0", and rangeA.End is "192.168.0.255".

var rangeA = IPAddressRange.Parse("192.168.0.0/255.255.255.0");

rangeA.Contains(IPAddress.Parse("192.168.0.34")); // is True.

rangeA.Contains(IPAddress.Parse("192.168.10.1")); // is False.

rangeA.ToCidrString(); // is 192.168.0.0/24

// rangeB.Begin is "192.168.0.10", and rangeB.End is "192.168.10.20".

var rangeB1 = IPAddressRange.Parse("192.168.0.10 - 192.168.10.20");

rangeB1.Contains(IPAddress.Parse("192.168.3.45")); // is True.

rangeB1.Contains(IPAddress.Parse("192.168.0.9")); // is False.

// Support shortcut range description. 

// ("192.168.10.10-20" means range of begin:192.168.10.10 to end:192.168.10.20.)

var rangeB2 = IPAddressRange.Parse("192.168.10.10-20");

// Support CIDR expression and IPv6.

var rangeC = IPAddressRange.Parse("fe80::/10"); 

rangeC.Contains(IPAddress.Parse("fe80::d503:4ee:3882:c586%3")); // is True.

rangeC.Contains(IPAddress.Parse("::1")); // is False.

// "Contains()" method also support IPAddressRange argument.

var rangeD1 = IPAddressRange.Parse("192.168.0.0/16");

var rangeD2 = IPAddressRange.Parse("192.168.10.0/24");

rangeD1.Contains(rangeD2); // is True.

// IEnumerable support, it's lazy evaluation.

foreach (var ip in IPAddressRange.Parse("192.168.0.1/23"))

{

    Console.WriteLine(ip);

}

// You can use LINQ via "AsEnumerable()" method.

var longValues = IPAddressRange.Parse("192.168.0.1/23")

  .AsEnumerable()

  .Select(ip => BitConvert.ToInt32(ip.GetAddressBytes(), 0))

  .Select(adr => adr.ToString("X8"));

Console.WriteLine(string.Join(",", longValues);

// Constructors from IPAddress objects.

var ipBegin = IPAddress.Parse("192.168.0.1");

var ipEnd = IPAddress.Parse("192.168.0.128");

var ipSubnet = IPAddress.Parse("255.255.255.0");

var rangeE = new IPAddressRange(); // This means "0.0.0.0/0".

var rangeF = new IPAddressRange(ipBegin, ipEnd);

var rangeG = new IPAddressRange(ipBegin, maskLength: 24);

var rangeH = new IPAddressRange(ipBegin, IPAddressRange.SubnetMaskLength(ipSubnet));

// Calculates Cidr subnets

var rangeI = IPAddressRange.Parse("192.168.0.0-192.168.0.254");

rangeI.ToCidrString();  // is 192.168.0.0/24
