Activity Part $2$: How IPv$4$ Addresses Are UsedA $32-$bit IP address is organized into four groups of eight bits each, which are presented as four decimal numbers separated by periods, such as $72\mathrm{.}56\mathrm{.}105\mathrm{.}12.$ The largest possible $8-$bit number is $11111111,$ which is equal to $255$ in decimal. Therefore, the largest possible IP address in decimal is $255\mathrm{.}255\mathrm{.}255\mathrm{.}255,$ which in binary is $11111111\mathrm{.}11111111\mathrm{.}11111111\mathrm{.}11111111.$ Each of the four numbers separated by periods is called an octet $($for $8$ bits$)$ and can be any number
