The IANA assigned our company the network $190\mathrm{.}87\mathrm{.}210\mathrm{.}0/24$ and we need to further divide it in at least $5$ different networks.

What the $4$ bytes of the new network mask in full notation $($x$.$x$.$x$.$x$)$ would be$?$

What the second subnet would be in CIDR notation?

What is the first IP address we could assign to a host in the $5$th subnet?Would you recommend acquiring $5$ networks, say $190\mathrm{.}87\mathrm{.}210\mathrm{.}0/24$ to $192\mathrm{.}87\mathrm{.}210\mathrm{.}4/24,$ if there were only $3$ hosts per network? Explain your answer.
