问如何将外部域绑定到.NET Core3.1Kestrel自托管应用程序？

EN

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
    {
        Host.CreateDefaultBuilder(args).ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.ConfigureKestrel(so =>
            {
                so.Listen(IPAddress.Any, 5000); //==> This is OK
            });
            webBuilder.UseStartup<Startup>();
        });
    }   
}

webBuilder.ConfigureKestrel(so =>
{
    so.Listen(IPAddress.Parse("112.250.22.33"), 80); //==> NOT OK
});
