Subnetting Questions:
1. Ans
IP Address: 192.168.123.148
Binary ID: 11000000 10101000 01111011 10010100
Binary Subnet Mask: 11111111.11111111.11111111.11111000
Bitwise AND operation b/w Binary ID and Binary Subnet Mask yields
11000000 10101000 01111011 10010000
Therefore IP range is : 192.168.123.144 - 192.168.123.151
And valid host IP address range is: 192.168.123.145 - 192.168.123.150
2. Ans
IP Address: 192.168.94.170
Binary ID: 11000000 10101000 01011110 10101010
Binary Subnet Mask: 11111111.11111111.11111111.11000000
Bitwise AND operation b/w Binary ID and Binary Subnet Mask yields
11000000 10101000 01011110 10000000
Hence Subnet Address
is: 192.168.94.128
3. Ans
IP Address: 172.22.0.0
Since the n/w class is B, there are 23-16 = 7 bits for subnets
Therefore the number of subnets = 2^7 = 128
Since there are 9 (32 - 23) bits in the host part, therefore, there are 2^9 - 2 = 510 hosts per subnet
4. Ans
IP Address: 192.168.18.64
Since the last IP address in this address is 192.168.18.95
Hence broadcast address is: 192.168.18.95
5. Ans
IP Address: 10.0.0.0
Subnet Mask: 255.255.240.0
Since the n/w class is B, there are 20-16 = 4 bits for subnets
Therefore the number of subnets = 2^4 = 16
Since there are 12 (32 - 20) bits in the host part, therefore, there are 2^12 - 2 = 4094 hosts per subnet
6. Ans
IP Address: 172.17.80.0
Since the last IP address in this n/w is 172.17.81.255
Hence Broadcast address is: 172.17.81.255
