a$)$ How many bits long is an ip $($v$4)$ address? $($No explanations.$))$

b$)$ Recall MAC address are written with $12$ digits $($like $0$a:$1$b:$2$c:$3$d:$4$e:$5$f$),$ whiere cach of thmen digits is a hex digit. How many bits long is a MAC address? $($No explanationis,$)$

c$)(10$ pts$)$ Therefore, how does the number of possible MAC addresses compare to the riumber of possible ip addresses? Based on your answers above, plug in expressions for the values of the following numerator and denominator, and simplify $($showing your work$)$ to obtain the actual numerical value $($or at least a very close approximation of it$)$ of the ratio:

$\frac{\frac{?}{?}\text{\#}\text{p}\text{o}\text{s}\text{s}\text{i}\text{b}\text{l}\text{e}\text{M}\text{A}\text{C}\text{a}\text{d}\text{d}\text{r}\text{e}\text{s}\text{s}\text{e}\text{s}}{\frac{?}{?}\text{\#}\text{p}\text{o}\text{s}\text{s}\text{i}\text{b}\text{l}\text{e}ip\text{a}\text{d}\text{d}\text{r}\text{e}\text{s}\text{s}\text{e}\text{s}}=$
