Explain How many hosts can be on each network? Consider a fixed subnet partition of a class B network number that will accommodate at least 76 networks.?

2^6=64 and 2^7=128



as per question, we need to accommodate 76 networks through fixed subnetting(ie
VLSM is not asked for); so we need to use /23 mask which gives 128 subnets



No. of hosts per subnet = (2^9)-2 = 510





Subnet Address = 172.16.0.0



Subnet mask = 255.255.254.0



Valid subnets = 256-254 = 0,2,4,6...254





Subnet Example: for Subnet 0.0





First Host = 0.1



Last Host = 1.254



Broadcast = 1.255
