Subnetting Practice Example: Class C Address (Simulation in Cisco Packet Tracer)
192.168.10.0 NETWORK ADDRESS
SUBNET MASK (255.255.255.128) (/25)
HOW MANY SUBNETS -- X.X.X.10000000 2^1 = 2
HOW MANY HOSTS/SUBNET -- 2^7 = 128
VALID SUBNETS -- 256 - 128 = 128 0 & 128
BROADCAST ADDRESS FOR EACH SUBNET -- 127 & 255
VALID HOSTS -- 1 126 (SUBNET 0)
129 254 (SUBNET 128)
