In this problem, you determine whether two IPv$4$ addresses reside on the same network, and show the process of making that determination. Given the following two CIDR entries:

$6\mathrm{.}180\mathrm{.}177\mathrm{.}207/20$

$6\mathrm{.}180\mathrm{.}173\mathrm{.}205/20$

a$.$ Determine the network address in dotted decimal notation for each entry.

b$.$ Indicate whether the entries are on the same or different networks.

c$.$ Explain step$-$by$-$step how a networked device would determine if these entries are on the same or different networks. Make sure to include the subnet mask and bitwise AND calculations in your explanation.
