CN - IP Subnetting - Class C Exercise

Computer Network

Exercise 1 : You are given an IP Address of 192.168.10.0/26. Calculate how many subnets and host per subnet are available in this network. Create the table for this network:

N =2² = 4 Network

H = 2⁶ = 64 – 2 = 62 Host

Network Address	Valid Host Range	Broadcast Address	Subnet Mask
193.168.10.0	192.168.10.1 – 192.168.10.62	192.168.10.63	255.255.255.192
192.168.10.64	192.168.10.65 - 192.168.10.126	192.168.10.127	255.255.255.192
192.168.10.128	192.168.10.129 - 192.168.10.190	192.168.10.191	255.255.255.192
192.168.10.192	192.168.10.193 - 192.168.10.254	192.168.10.255	255.255.255.192

Exercise 2 : You are given an IP Address of 223.14.3.0/26. Calculate how many subnets and host per subnet are available in this network. Create the table for this network:

N =2⁴ = 16 Network

H = 2⁴ = 16 – 2 = 14 Host

Network Address	Valid Host Range	Broadcast Address	Subnet Mask
223.14.3.0	223.14.3.1 - 223.14.3.14	223.14.3.15	255.255.255.240

223.14.3.96	223.14.3.97 - 223.14.3.110	223.14.3.111	255.255.255.240
223.14.3.112	223.14.3.113 - 223.14.3.126	223.14.3.127	255.255.255.240
223.14.3.128	223.14.3.129 - 223.14.3.142	223.14.3.143	255.255.255.240
223.14.3.144	223.14.3.145 - 223.14.3.158	223.14.3.159	255.255.255.240
