Which term identifies the network that a given IP address belongs to (IPv4)?

• A. Network ID
• B. Network Settings
• C. Nonrepudiation
• D. Numbering System (Binary)

Answer: (A)

The network portion of an IPv4 address defines which network the address belongs to—that is the network ID, and it’s determined by the subnet mask. All devices on the same network share this network ID, while the host part varies. For example, with 192.168.1.10 and a 255.255.255.0 mask, the network ID is 192.168.1.0; with a 255.255.0.0 mask, the network ID would be 192.168.0.0. This shows how the network is identified by the network ID, not by the host portion. Other terms don’t describe the network itself: Network Settings refers to configuration data, Nonrepudiation is about proving data origin and integrity, and Numbering System (Binary) covers representation, not network identification.
