In Azure Application Insights how do I unmask client IP address

I noticed all the exception loggings in the ‘Failures’ come client Ip zeroed. How do I turn this one or unmask so the client IP is visible on every logging?

    You need to disable IP-masking. Though it is not possible to through Azure Portal directly you can do it using ARM templates, PowerShell, etc.

    Thanks @ZakiMa for inputs, I do agree and I followed the same Microsoft-Document and as an alternative(if you do not have permissions to use Powershell or ARM and change the settings) way use telemetry with code:

    RithIpTest.cs:

    public class RithIpTest : ITelemetryInitializer
{
    public void Initialize(ITelemetry ri_tel)
    {
        ISupportProperties ri_pt = ri_tel as ISupportProperties;

        if (ri_pt != null && !ri_pt.Properties.ContainsKey("client-ip"))
        {
            string ri_cl = ri_tel.Context.Location.Ip;
            ri_pt.Properties.Add("client-ip", ri_cl);
        }
    }
}

    In program.cs added:

    var rb = WebApplication.CreateBuilder(args);
rb.Services.AddControllersWithViews();
rb.Services.AddApplicationInsightsTelemetry(rb.Configuration["ApplicationInsights:ConnectionString"]);
rb.Services.AddSingleton<ITelemetryInitializer, RithIpTest>();
------
------
app.Run();

    With the above code, in customdimensions you will able to get the client ip .

    Output:

    When Client is running:

    When run from local:

    This will work for traces , failures, requests, etc.
