For each of the IP Addresses below, calculate the following for the network it belongs to:

a$.$ The Network Address

b$.$ The Broadcast Address

c$.$ The total number of useable hosts on the network

Host IP: $172\mathrm{.}30\mathrm{.}1\mathrm{.}33$ Subnet Mask: $255\mathrm{.}255\mathrm{.}0\mathrm{.}0$

Host IP: $192\mathrm{.}30\mathrm{.}1\mathrm{.}33$ Subnet Mask: $255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

Host IP: $10\mathrm{.}4\mathrm{.}16\mathrm{.}46$ Subnet Mask: $255\mathrm{.}0\mathrm{.}0\mathrm{.}0$

Host IP: $192\mathrm{.}168\mathrm{.}3\mathrm{.}219$ Subnet Mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}224$

$($Note: #$4\text{'}$s subnet mask borrows $1\text{'}$s from the last octet!$)$

How to use the IPv$4$ address worksheet $($also watch the video demonstration$)$:

Translate the subnet mask into binary. Split between network and host portions

Translate the host IP address from dotted decimal into binary. Split between network and host portions.

Calculate the binary Network Address by combining:

a$.$ The network portion of the Host IP address

b$.$ All zeros for the host portion of the network mask

c$.$ Translate the resulting binary string into "dotted decimal" form which will produce the network

address

Calculate the Broadcast Address by combining:

a$.$ The network portion of the Host IP address

b$.$ All ones for the host portion of the network mask

c$.$ Translate the resulting binary string into dotted decimal form which will produce the broadcast

address.

Use the equation $2^n-2($where $n$ is the number of binary $"0"$ bits in the subnet mask$)$ to calculate the

number of usable host addresses.
