Managing the Router over the Network IP Addresses and Subnet Masks To manage a device over the network the Router must be correctly configured with the following IP information m An IP address m A Subnet Mask Each device on your network must have a unique IP address to operate correctly An IP address identifies the address of the device to which data is being sent and the address of the destination network IP addresses have the format n n n x where n is a decimal number between 0 and 255 and x is a number between 1 and 254 inclusive However an IP Address alone is not enough to make your device operate In addition to the IP address you need to set a subnet mask All networks are divided into smaller sub networks and a subnet mask is a number that enables a device to identify the sub network to which it is connected 114 APPENDIX B IP ADDRESSING For your network to work correctly all devices on the network must have m The same sub network address m The same subnet mask The only value that will be different is the specific host device number This value must always be unique An example IP address is 192 168 100 8 However the size of the network determines the structure of this IP Address In using the Router you will probably only encounter two types of IP Address and subnet mask structures Type One In a small network the IP address of 192 168 100 8 is split into two parts m Part one 192 168 100
