“AND” the IP address with the subnet mask. Default Subnet Masks:

Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.0 ANDING Equations: 1 AND 1 = 1 1 AND 0 = 0 0 AND 1 = 0 0 AND 0 = 0 Sample:

What you see...

IP Address: 192 . 100 . 10 . 33

What you can figure out in your head...

Address Class: C

Network Portion: 192 . 100 . 10 . 33

Host Portion: 192 . 100 . 10 . 33

In order for you computer to get the same information it must AND the IP address with the subnet mask in binary.

ANDING with the default subnet mask allows your computer to figure out the network portion of the address.

world still sees the network as 192.100.10.0, but the internal computers and routers see five smaller subnetworks. Each independent of the other. This can only be accomplished by using a custom subnet mask. A custom subnet mask borrows bits from the host portion of the address to create a subnetwork address between the network and host portions of an IP address. In this example each range has 14 usable addresses in it. The computer must still AND the IP address against the custom subnet mask to see what the network portion is and which subnetwork it belongs to.

IP Address: 192 . 100 . 10 . 0

In the next set of problems you will determine the necessary information to determine the 1 1 0 0 0 0 0 0 . 1 1 0 0 1 0 0 . 0 0 0 0 1 0 1 0 . 0 0 1 0 0 0 0 1 1 1 1 1 1 1 1 1 . 1 1 1 1 1 1 1 . 1 1 1 1 1 1 1 1 . 1 1 1 1 0 0 0 0 1 1 0 0 0 0 0 0 . 1 1 0 0 1 0 0 . 0 0 0 0 1 0 1 0 . 0 0 1 0 0 0 0 0 (255 . 255 . 255 . 240) (192 . 100 . 10 . 33) (192 . 100 . 10 . 32)

Four bits borrowed from the host portion of the address for the custom subnet mask.

The ANDING process of the four borrowed bits shows which range of IP addresses this particular address will fall into.

The binary value of the last bit borrowed is the range. In this problem the range is 64. The first and last range of addresses are not usable. The first usable range of addresses is: 165.100.0.64 to 165.100.0.127 The first address in each subnet range is the subnet number

.

The last address in each subnet range is the subnet broadcast address.
