Which process extracts the network address from an IP address.
Default masking process extracts the network address from an IP address.
Type "ipconfig" to find your network address. The network address is found by performing a logical AND operation on your IP address and the subnet mask. For example, if you IP is 192.168.1.101 and subnet mask is 255.255.255.0, then the network address is 192.168.1.0.
To divide a given network address into two or more subnets, you use subnet masks. The default subnet masks for class A networks is 255.0.0.0, for class B is 255.255.0.0, and for class C is 255.255.255.0, which signify a network without subnets. If the router's LAN IP address is 192.168.1.1, please type in IP address 192.168.1.x (x is from 2 to 253), subnet mask 255.255.255.0, and default gateway 192.168.1.1.
A subnet mask is a number that defines a range of IP addresses that can be used in a network. ... A subnet mask hides, or "masks," the network part of a system's IP address and leaves only the host part as the machine identifier. A common subnet mask for a Class C IP address is 255.255.255.0.
