sorry for my drawing talent but you can see clearly that domain is any x, but range of function is from -pi/2 to pi/2...these two horizontal lines

arctan is inverse function to tan(x), so the domain and range are flipped for tan(x) , Domain is (-pi/2, pi/2). Range is All Real therefore for arctan: Domain is All Real, Range is (-pi/2, pi/2)
