IPAddressRange Class Library

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 conatins check. This library supports both IPv4 and IPv6.

Example

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<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 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

IPAddressRange.Signed

[Superseded] This package became only metadata package for installing "IPAddressRange" NuGet package, because "IPAddressRange" NuGet package became strong-named assembly.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.

ZNetCS.AspNetCore.IPFiltering

A middleware that allows whitelist or blacklist incomming requests based on IP address. It can be configured using single IP address or ranges. It supports single IP, IP range IPv4 and IPv6. There is also possible to ignore specific paths from IP filtering.

WhoisClient.NET

This library is a WHOIS protocol client used to search owner information by IP address or domain name. This library determines the WHOIS server automatically and queries the referral server recursively. The response of the whois query contains strongly typed values, and the raw output.
