MyIpAddress 1.0.0

MyIpAddress MyIpAddress is a .NET library that provides utilities for working with IP addresses, including validation, retrieval of local IPv4 addresses, and access control based on IP addresses.

Installation You can install the MyIpAddress package via NuGet Package Manager. Run the following command in your Package Manager Console:

Install-Package MyIpAddress Alternatively, you can add it to your project file:

xml

Open In Editor Edit Copy code <PackageReference Include="MyIpAddress" Version="1.0.0" /> Usage To use the IpAddressHelper class, you need to register the required services in your Startup.cs file:

public void ConfigureServices(IServiceCollection services) { services.AddHttpContextAccessor(); services.AddSingleton<IConfiguration>(Configuration); services.AddSingleton<IpAddressHelper>(); } You can then inject IpAddressHelper into your classes:

public class MyService { private readonly IpAddressHelper _ipAddressHelper;

public MyService(IpAddressHelper ipAddressHelper)
{
    _ipAddressHelper = ipAddressHelper;
}

public void ExampleMethod()
{
    string localIP = _ipAddressHelper.GetLocalIPv4Address();
    bool isValid = _ipAddressHelper.IsValidIpAddress(localIP);
    bool accessGranted = _ipAddressHelper.IsAccessGranted("AllowedIPs");
}

} Methods IsValidIpAddress(string ipAddress) Validates if the provided IP address is in a correct format.

GetLocalIPv4Address() Retrieves the local IPv4 address of the machine.

IsAccessGranted(string IPs) Checks if the client's IP address is in the allowed list defined in the configuration.

//public IActionResult CheckAccess() { // Retrieve the allowed IPs from configuration string allowedIPs = _configuration["AllowedIPs"];

bool isGranted = _ipAddressHelper.IsAccessGranted(allowedIPs);
if (isGranted)
{
    return Ok("Access granted.");
}
else
{
    return Forbid("Access denied.");
}

}

public partial class Default : System.Web.UI.Page { private IpAddressHelper _ipAddressHelper;

protected void Page_Load(object sender, EventArgs e)
{
    // Retrieve the service provider from the application context
    var serviceProvider = (IServiceProvider)Application["ServiceProvider"];
    _ipAddressHelper = serviceProvider.GetService<IpAddressHelper>();

    // Example usage
    string localIP = _ipAddressHelper.GetLocalIPv4Address();
    bool isValid = _ipAddressHelper.IsValidIpAddress(localIP);
    bool accessGranted = _ipAddressHelper.IsAccessGranted("AllowedIPs");
}

}

using Microsoft.Extensions.DependencyInjection;

public class Global : HttpApplication { protected void Application_Start(object sender, EventArgs e) { var services = new ServiceCollection(); services.AddHttpContextAccessor(); services.AddSingleton<IConfiguration>(new ConfigurationBuilder().Build()); services.AddTransient<IpAddressHelper>();

    // Build the service provider
    var serviceProvider = services.BuildServiceProvider();
    // Store the service provider for later use
    Application["ServiceProvider"] = serviceProvider;
}
