Final answer:
The question refers to IPv4 addresses and subnet masks, which are used to identify networks and manage traffic within and between organizational networks. Each IPv4 address and subnet mask is written in dot-decimal notation and indicates specific parts of the network. The correct answer is A. IPv4 addresses.
Step-by-step explanation:
The networking information being referred to in the question is likely IPv4 addresses and subnet masks. When discussing address ranges for organizations and mentioning subnet masks, this typically relates to how IP networks are subdivided or 'subnetted' for organizing and routing network traffic. IPv4 addresses are written in dot-decimal notation as four octets separated by dots (for example, 192.168.0.0), with each octet ranging from 0 to 255. Subnet masks are also noted in a similar format (such as 255.255.255.0) and they indicate which portion of the IP address represents the network and which part represents the host within that network.
Organizational networks are usually assigned specific ranges of IP addresses to ensure that devices within their network can communicate with each other and with external networks while maintaining a structured addressing scheme. The subnet mask is critical in identifying the size of the network and the number of hosts it can support. Thus, the correct answer to the quiz question is A. IPv4 addresses.
