 Rod:

 The subnet mask is 255.255.255.0 on most small networks this would be a
 network containing 255 workstations. The subnet mask is used to block out
 the upper part of the network address where ever a bit appears the
 address that part of the address is blocked out. In the 255.255.255.0
 only the lower 255 ( the zero ) are allowed to pass through the mask.
 If you have a bigger network then second from the right would be a smaller
 value digit. This saves the network software from having to decode the
 whole address which would slow the network down.
