Address Class
Default Subnet Mask
Custom Subnet Mask
Required subnets is 14 which is not power of 2. The next number which is power of 2 is 16 (24).Therefore extra 4 number of 1's are required to be borrowed in the custom subnet to fulfill 14 subnets requirement.(as 2x =no of subnets where x= no of borrowed bit)
Therefore the custom subnet mask is:
(11111111.11111111.11111111.11110000)2 = (255.255.255.240)10
Total Number of Subnets
Default subnet mask is 255.255.255.0(11111111.11111111.11111111.00000000)
Custom subnet mask is 255.255.255.240(11111111.11111111.11111111.1111000)
Therefore total number of subnets= 2x(where x = number of 1's borrowed from default subnet to make custom subnet. here x= 4) = 24 = 16
Total Number of Host Addresses
Number of host addresses per subnet = 2y (where y = number of unborrowed bit or number of 0 in custom subnet, here y =4 ) = 24 = 16
Therefore total number of possible host addresses = 16 *16 = 256
Total number of required host address = 14 * 14 = 196
Number of Usable Addresses
Number of Bits Borrowed
What is the 10th Subnet Range?
What is the subnet number for the 2nd Subnet?
2nd subnet ranges from (11000000.00001010.00001010.00100000)2 = (192.10.10.32)10 to (11000000.00001010.00001010.00101111)2 = (156.100.0.47)10
The 8 bits in the subnet address indicate subnet number.As the subnet is 2, it is written as 00100000 to 00101111 to represent 2nd subnet.
What is the broadcast address for the 12th Subnet?
For 12th subnet the last address is (11000000.00001010.00001010.11001111)2 = (192.10.10.207)10
The last 4 bits are set to all 1's to represent broadcast address.
What are the usable addresses for the 10thSubnet?
10th subnet ranges from (11000000.00001010.00001010.10100000)2 = (192.10.10.160)10 to (11000000.00001010.00001010.10101111)2 = (156.100.25.175)10
The usable addresses range from 192.10.10.161 to 192.10.10.169.
As the first and last address in the subnet mask is used for subnet address and broadcast address respectively.

Default Subnet Mask
Custom Subnet Mask
Required subnets is 1000 which is not power of 2. The next number which is power of 2 is 1024 (210).Therefore extra 10 number of 1's are required to be borrowed in the custom subnet to fulfill 1000 subnets requirement.(as 2x =no of subnets where x= no of borrowed bit)
Therefore the custom subnet mask is:
(11111111.11111111.11111111.11000000)2 = (255.255.255.192)10
Total Number of Subnets
Default subnet mask is 255.255.0.0(11111111.11111111.00000000.00000000)
custom subnet mask is 255.255.255.192(11111111.11111111.11111111.1100000)
Therefore total number of subnets= 2x(where x = number of 1's borrowed from default subnet to make custom subnet. here x= 10) = 210 = 1024
Total Number of Host Addresses
Number of host addresses per subnet = 2y (where y = number of unborrowed bit or number of 0 in custom subnet, here y =6 ) = 26 = 64
Therefore total number of possible host addresses = 64 * 1024 = 65,536
Total number of required host address = 60 *1000 = 60,000
Number of Usable Addresses
Number of Bits Borrowed
What is the 10th Subnet Range?
What is the subnet number for the 2nd Subnet?
2nd subnet ranges from (10011100.01100100.00000000.10000000)2 = (156.100.0.128)10 to (10011100.01100100.00000000.10111111)2 = (156.100.0.191)10
The 10 bits in the subnet address indicate subnet number.As the subnet is 2, it is written as 00000000.10000000 to 00000000.10111111 to represent 2nd subnet.
What is the broadcast address for the 12th Subnet?
For 12th subnet the last address is (10011100.01100100.00000011.00111111)2 = (156.100.3.63)10
The last 6 bits are set to all 1's to represent broadcast address.
What are the usable addresses for the 100thSubnet?
100th subnet ranges from (10011100.01100100.00011001.00000000)2 = (156.100.25.0)10 to (10011100.01100100.00011001.00111111)2 = (156.100.25.63)10
The usable addresses range from 156.100.25.1 to 156.100.25.62.
As the first and last address in the subnet mask is used for subnet address and broadcast address respectively.

Class C( The range of first 8 bit MSB of address for classs B is 192 to 223)Default Subnet Mask
For class C default subnet mask is 255.255.255.0 or 24(number of 1's in 255.255.255.0 )Custom Subnet Mask
Required subnets is 14 which is not power of 2. The next number which is power of 2 is 16 (24).Therefore extra 4 number of 1's are required to be borrowed in the custom subnet to fulfill 14 subnets requirement.(as 2x =no of subnets where x= no of borrowed bit)
Therefore the custom subnet mask is:
(11111111.11111111.11111111.11110000)2 = (255.255.255.240)10
Total Number of Subnets
Default subnet mask is 255.255.255.0(11111111.11111111.11111111.00000000)
Custom subnet mask is 255.255.255.240(11111111.11111111.11111111.1111000)
Therefore total number of subnets= 2x(where x = number of 1's borrowed from default subnet to make custom subnet. here x= 4) = 24 = 16
Total Number of Host Addresses
Number of host addresses per subnet = 2y (where y = number of unborrowed bit or number of 0 in custom subnet, here y =4 ) = 24 = 16
Therefore total number of possible host addresses = 16 *16 = 256
Total number of required host address = 14 * 14 = 196
Number of Usable Addresses
Number of usable addresses = Total number of host address=256 - 2 =254( 2 is subtracted as 2 addresses are used for subnet address and broadcast address)Number of Bits Borrowed
