Final answer:
The network address of a host with an IP address can be determined by applying a subnet mask to the IP address.
Step-by-step explanation:
The network address of a host with an IP address can be determined by applying a subnet mask to the IP address. The subnet mask determines the network portion of the IP address. The network address is obtained by performing a bitwise AND operation between the IP address and the subnet mask.
For example, let's say the IP address is 192.168.1.10 and the subnet mask is 255.255.255.0. Converting both to binary, we have:
IP address: 11000000.10101000.00000001.00001010
Subnet mask: 11111111.11111111.11111111.00000000
Performing the bitwise AND operation, we get:
Network address: 11000000.10101000.00000001.00000000
