Instead of using model binding, id suggest using a tryupdate call.

[HttpPost]
public ActionResult Manipulation(FormCollection formCollection)
{
  MyModel model = new MyModel();

  if(TryUpdate(Model))
  {
      enter code here
  }

  if(somthing)
  model.IPAddress="100.100.100.100";
  return View(model);
}

Check out my answer to another post for the general structure i use. Its never failed me before and i believe it covers all bases when updating models from user input.
