The network mask


The network mask is more properly called the subnetwork mask. However, it is generally referred to as the network mask.








It is the network mask and its implications on how IP addresses are interpreted locally on an IP network segment that concerns us most here, as this determines what (if any) sub-networking occurs.








The standard (sub-) network mask is all the network bits in an address set to '1' and all the host bits set to '0'. This means that the standard network masks for the three classes of networks are:-








A Class network mask: 255.0.0.0


B Class network mask: 255.255.0.0


C Class network mask: 255.255.255.0





There are two important things to remember about the network mask:-





The network mask affects only the local interpretation of local IP numbers (where local means on this particular network segment);


The network mask is not an IP number - it is used to modify how local IP numbers are interpreted locally.Can any body tell how to mask the ip address...?
