What is my vocal range?

My range is around e3 to c6, but i can sing a few notes higher in a opera-ish type voice. the notes i am most comfortable with(i think its called a tessitura) are around d5, going up and down a few notes from there. Can somebody tell me what vocal range i am in? i've heard anything from alto to mezzo soprano to soprano and i would really like to know. thanks!
