Local Area Network

B

This question asks about the private ranges of IPv4 addresses. The private ranges of each class of IPv4 are listed below:

Class A private IP address ranges from 10.0.0.0 to 10.255.255.255

Class B private IP address ranges from 172.16.0.0 to 172.31.255.255

Class C private IP address ranges from 192.168.0.0 to 192.168.255.255

Only the network 172.28.0.0/16 belongs to the private IP address (of class B).

The correct answer is that none of the provided networks can guarantee communication between devices without accessing the Internet.

Explanation:

The question implies that there is a specific network range that allows devices to communicate without accessing the Internet. However, in reality, the ability for devices to communicate without the Internet is dependent on the network architecture and configuration.

In general, two devices can communicate with each other as long as they are connected to the same local network, which is a network that is designed to serve a specific geographic area, such as a building or campus. Local networks can be set up using various technologies, including Ethernet, Wi-Fi, or Bluetooth.

To enable communication within a local network, devices are assigned IP addresses that are within the same network range, and they use a protocol, such as TCP/IP, to exchange data. The IP address range that is used for a local network is typically assigned by the network administrator and is not related to the ranges provided in the answer choices.

In summary, the question is flawed because there is no specific network range that guarantees communication between devices without accessing the Internet. The ability for devices to communicate without the Internet is determined by the local network configuration and technology used, and the IP address range used for the local network is assigned by the network administrator, not based on a specific pre-defined range.
