Netmask Address

Netmask Address is the IP Address used to determine the "division" long network bit by bit host. Netmask is also used to find the network address. Why should determine the length of the network using a netmask bits? how to find the network address using a netmask? Is not the host bits long division following the standard IP address classes?


For the first question can be answered as follows. Computers are basically "stupid", unless programmed and was told in detail. Computers can not tell the difference IP address keals a, b, and c. So the computer does not know the length of the network bit by bit host of a specific IP address. To fix it in the make netmask address.



Netmask address on the form by replacing all the bits of the network by one and replace all the host bits to 0. for example, the IP address 167.205.9.35 netmask address 255.255.0.0 will produce.
