#Computers on a network identify and communicate with other computers using

#addresses and protocols. One such addressing scheme is the $32-$bit IP $($Internet

Protocol$)$

#addressing. Each IP address is broken up into four $1-$byte numbers $($called octets$)$

#separated by periods. For example, a valid IP address is $192\mathrm{.}168\mathrm{.}1\mathrm{.}15$

#A bitmask is a binary number applied using a bitwise operator to perform one

#of the following operations:

#$1.$ Determining which bits are turned on $($i$.$e$.,1)$ in another binary value

#$2.$ Turning bits off in another binary value

#$3.$ Turning bits on in another binary value

#$4.$ Toggling bits on and off in another binary value

#Bitmasks are commonly found in computer networking, where "netmasks" divide

#networks into subnets or smaller networks. Using a netmask of $255\mathrm{.}255\mathrm{.}255\mathrm{.}128,$

#a computer with the IP address $192\mathrm{.}168\mathrm{.}1\mathrm{.}130$ would belong the $192\mathrm{.}168\mathrm{.}1\mathrm{.}128$

subnet.
