Lower range can be found out by keeping all the bits off (means the corresponding numerical value is not added), Higher range can be calculated by turning all the bits on (except the 1stbit which is reserved as off). The subnet and broadcast address must be found and reserved. VLSM routes include: Click here for information on how to choose a classless routing In this example, the naming convention for the subnet mask is / and then the number, where the number tells the router which bits are the network portion of the address.
