Am I a tenor, countertennor, what type of singer am I?

I am a guy and am told to have an unusually large vocal range. It's one note short of 4 octaves. The lowest note is 1 note short of 2 complete octaves from middle C and my highest note is exactly 2 C's above middle C. I was told I was a tenor but am noticing that my upper range has grown over the past month and the description is my current range. What kind of singer am I? If I am a tenor, what type? I don't think I'm a baritone because my voice is pretty light and several people canceled out baritone when hearing me sing. If you think I'm a baritone, I would be willing to hear that answer.
