Written on 23:24 by Ahmet Emir
This is done the aforementioned way as the above-mentioned subnet mask, except that we aloof accept added subnets
and beneath hosts per subnet available.
172.16.0.0 = Network address
255.255.255.224 = Subnet mask
Subnets? 211 = 2048.
Hosts? 25 – 2 = 30.
Valid subnets? 256 – 224 = 32. 0, 32, 64, 96, 128, 160, 192, 224.
Broadcast abode for anniversary subnet?
Valid hosts?
The afterward table shows the aboriginal eight subnets:
Subnet 0.0 0.32 0.64 0.96 0.128 0.160 0.192 0.224
First host 0.1 0.33 0.65 0.97 0.129 0.161 0.193 0.225
Last host 0.30 0.62 0.94 0.126 0.158 0.190 0.222 0.254
Broadcast 0.31 0.63 0.95 0.127 0.159 0.191 0.223 0.255
This abutting table shows the aftermost eight subnets:
Subnet 255.0 255.32 255.64 255.96 255.128 255.160 255.192 255.224
First host 255.1 255.33 255.65 255.97 255.129 255.161 255.193 255.225
Last host 255.30 255.62 255.94 255.126 255.158 255.190 255.222 255.254
Broadcast 255.31 255.63 255.95 255.127 255.159 255.191 255.223 255.255
