Answer 1

Json in ApiController with two parameters has a signature of,

protected internal JsonResult<T> Json<T>(
T content,
JsonSerializerSettings serializerSettings
)

Json in Controller with two parameters has a signature of,

protected internal JsonResult Json(
object data,
JsonRequestBehavior behavior
)

getipaddressController inherited from ApiController, but you used Controller method Json. Use,

return new JsonResult()
{
 Data = ipAddress,
 JsonRequestBehavior = JsonRequestBehavior.AllowGet
};

If you still want the behavior.
