Subnetting

Q1: <div class="Aptitude-td-qtxt table-responsive w-100">Using the following illustration, what would be the IP address of E0 if you were using the eighth subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP 
address in the range. The zero subnet should not be considered valid for this question.

A 192.168.10.66

B 192.168.100.254

C 192.168.10.143

D 192.168.10.142

E 192.168.10.126

ANS:A - 192.168.10.142

A /28 is a 255.255.255.240 mask. Let's count to the ninth subnet (we need to find the broadcast address of the eighth subnet, so we need to count to the ninth subnet). Starting at 16 (remember, the question stated that we will not use subnet zero, so we start at 16, not 0), 16, 32, 48, 64, 80, 96, 112, 128, 144. The eighth subnet is 128 and the next subnet is 144, so our broadcast address of the 128 subnet is 143. This makes the host range 129-142. 142 is the last valid host.
