IPNetworkChange Class

Syntax

public static class IPNetworkChange

Remarks

The IPNetworkChange class provides a mechanism to subscribe to and receive notifications about network interface address changes. This is useful for applications that need to react to the addition, removal, or modification of IP addresses on the local machine.

You can subscribe to the following events:

• NetworkAddressChanged: Raised when an IP address is added, removed, or changed on any network interface.
• InputAddressChanged: Raised when an IP address is added, removed, or changed on an input interface.

These events are static, meaning you can access them directly through the IPNetworkChange class without creating an instance of the class.

Events

using System;
using System.Net.Sockets;

public class NetworkListener
{
    public static void Main(string[] args)
    {
        System.Net.IPNetworkChange.NetworkAddressChanged += NetworkAddressChangedHandler;
        Console.WriteLine("Listening for network address changes...");
        Console.WriteLine("Press Enter to exit.");
        Console.ReadLine();

        System.Net.IPNetworkChange.NetworkAddressChanged -= NetworkAddressChangedHandler;
    }

    private static void NetworkAddressChangedHandler(object sender, EventArgs e)
    {
        Console.WriteLine("Network address changed detected!");
        // You can add logic here to check for new IP addresses or other changes
    }
}
