a) English Class
For the host IP address, identify the prefix
192.168.10.1/
Identify the LSB (least significant bit)
Identify the Subnet ID to which the host belongs
Identify the broadcast address
Identify the usable range of host IP addresses
The given IP 192.168.10.1/
If the number of hosts is 25 then the size of the block which fulfills the requirement "=2^5"
For the block size of 32, the number of host bits "=2^5" , hence host bits will be 5, which is also called least significant bits.
If hosts bit are 5 then number of network bit = 32-5 = 27 network bits
Number of network bits is 27, then sub-net mask = 8 | 8 | 8 | 3
"=255.255.255.224"
So, prefix 192.168.10.1/27
Least significant bit =5
The belonging sub-net = 192.168.10.0
Broadcast address = 192.168.10.31
Usable range of host IP = 192.168.10.1 to 192.168.10.30
