Refer to the following figure. What is the most appropriate summarization for these routes?

$10\mathrm{.}0\mathrm{.}0\mathrm{.}010\mathrm{.}0\mathrm{.}1\mathrm{.}010\mathrm{.}0\mathrm{.}2\mathrm{.}010\mathrm{.}0\mathrm{.}3\mathrm{.}0$

Note: The acceptable format for the answer is $x.x.x.\frac{x}{Y}$ where each $x$ is a number between $0$ and $255$ and $Y$ is a number between $1$ and $32.$
