ANDING WithDefault subnet masks

Every IP address must be accompanied by a subnet mask. By now you should be able to lookat an IP address and tell what class it is. Unfortunately your computer doesn’t think that way.For your computer to determine the network and subnet portion of an IP address it must“AND” the IP address with the subnet mask.

Default Subnet Masks:Class A 255.0.0.0Class B 255.255.0.0Class C 255.255.255.0

ANDING Equations:1 AND 1 = 11 AND 0 = 00 AND 1 = 00 AND 0 = 0

Sample:

What you see...

IP Address: 192 . 100 . 10 . 33

What you can figure out in your head...

Address Class: CNetwork Portion: 192 . 100 . 10 . 33Host Portion: 192 . 100 . 10 . 33

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

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

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 11 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 0 0 0 01 1 0 0 0 0 0 0 . 1 1 0 0 1 0 0 . 0 0 0 0 1 0 1 0 . 0 0 0 0 0 0 0 0

ANDING WithCustom subnet masks

When you take a single network such as 192.100.10.0 and divide it into five smaller networks(192.100.10.16, 192.100.10.32, 192.100.10.48, 192.100.10.64, 192.100.10.80) the outsideworld still sees the network as 192.100.10.0, but the internal computers and routers see fivesmaller subnetworks. Each independent of the other. This can only be accomplished by usinga custom subnet mask. A custom subnet mask borrows bits from the host portion of theaddress to create a subnetwork address between the network and host portions of an IPaddress. In this example each range has 14 usable addresses in it. The computer must stillAND the IP address against the custom subnet mask to see what the network portion is andwhich subnetwork it belongs to.

IP Address: 192 . 100 . 10 . 0Custom Subnet Mask: 255.255.255.240

Address Ranges: 192.10.10.0 to 192.100.10.15 (Invalid Range)192.100.10.16 to 192.100.10.31 (1st Usable Range)192.100.10.32 to 192.100.10.47 (Range in the sample below)192.100.10.48 to 192.100.10.63192.100.10.64 to 192.100.10.79192.100.10.80 to 192.100.10.95192.100.10.96 to 192.100.10.111192.100.10.112 to 192.100.10.127192.100.10.128 to 192.100.10.143192.100.10.144 to 192.100.10.159192.100.10.160 to 192.100.10.175192.100.10.176 to 192.100.10.191192.100.10.192 to 192.100.10.207192.100.10.208 to 192.100.10.223192.100.10.224 to 192.100.10.239192.100.10.240 to 192.100.10.255 (Invalid Range)

In the next set of problems you will determine the necessary information to determine thecorrect subnet mask for a variety of IP addresses.

Four bits borrowed from the hostportion of the address for thecustom subnet mask.

The ANDING process of the four borrowed bitsshows which range of IP addresses thisparticular address will fall into.
