IPAddressRange.Signed 4.1.1

[Superseded] This package became  only metadata package for installing "IPAddressRange" NuGet package, because "IPAddressRange" NuGet package became strong-named assembly.
Please consider to installing "IPAddress" NuGet package directly instead of this package.
----------------------------
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.

Install-Package IPAddressRange.Signed -Version 4.1.1
dotnet add package IPAddressRange.Signed --version 4.1.1
<PackageReference Include="IPAddressRange.Signed" Version="4.1.1" />
For projects that support PackageReference, copy this XML node into the project file to reference the package.

Example

using NetTools;

// IEnumerable<IPAddress> 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 rangeH = new IPAddressRange(ipBegin, IPAddressRange.SubnetMaskLength(ipSubnet));

// Calculates Cidr subnets
var rangeI = IPAddressRange.Parse("192.168.0.0-192.168.0.254");
