In this assignment, we assume we create a small LAN using a switch and $2$ computers, Host A and Host B$.$ Assume Host A IP address is $212\mathrm{.}149\mathrm{.}5\mathrm{.}50,$ Host B IP address is $212\mathrm{.}149\mathrm{.}5\mathrm{.}150,$ and subnet mask is $255\mathrm{.}255\mathrm{.}255\mathrm{.}0.$ What is the Network ID for Host A$?$
