3.1.6 2. A workstation has been assigned the following IP addressing information: IP address: 192.168.1.26 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.254 DNS server: 192.168.1.1 Given this information, what is the IP address of the network where this host resides?

192.168.1.0 The IP address includes both the network and the host address. The subnet mask is a 32-bit number associated with each IP address that identifies the network portion of the address. In binary form, the subnet mask is always a series of 1s followed by a series of 0s (1s and 0s are never mixed in sequence in the mask). In this example, the decimal form of the subnet mask is 255.255.255.0. This specifies that the network address in this example is 192.168.1.0 192.168.1.255 is the broadcast address for this network. A network address of 192.168.0.0 would require a subnet mask of 255.255.0.0. A network address of 192.0.0.0 would require a subnet mast of 255.0.0.0
