The equation of the hyperbola is given in the form $16x^2 - y^2 = 1$, which can be rewritten as $\frac{x^2}{1/16} - \frac{y^2}{1} = 1$. Comparing this with the standard form of a hyperbola $\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1$, we find $a^2 = \frac{1}{16}$ and $b^2 = 1$. The eccentricity $e$ of a hyperbola is given by $e = \sqrt{1 + \frac{b^2}{a^2}}$. Substituting $a^2 = \frac{1}{16}$ and $b^2 = 1$, we get $e = \sqrt{1 + 16} = \sqrt{17}$.
