When a network is subnetted it is seperated into groups of I.P addresses that
make up seperate networks within a larger range of I.P addresses. This
allows companies to more efficiently utilize I.P addresses, for example you
would not have to use the 192.168.x.x scheme for one network and a 10.62.x.x
scheme for a second network, with subnetting you can break up the 192.168.x.x
addresses into "blocks" that keep the 2 networks seperate. One segment could
be in the 192.168.1.1 to 192.168.1.100 range and the other in the
192.168.1.101 to 192.168.1.200 range and so on.
The subnet mask tells the router which "block" your computer belongs to and
routs the data properly. With the 255.255.255.0 mask the whole range of the
192.168.x.x scheme is within the same network, it is not segmented.
