The correct answer is C. An IPv4 address is 32 bits long.
An IPv4 address is a 32-bit number that is used to identify a device on a computer network. It is typically written in decimal form, with each of the four numbers separated by a dot. For example, the IPv4 address of Google’s website is 172.217.16.254.
IPv4 addresses are divided into two parts: the network portion and the host portion. The network portion identifies the network that the device is on, and the host portion identifies the specific device on that network.
IPv4 addresses are assigned by the Internet Assigned Numbers Authority (IANA). IANA is responsible for allocating IP addresses to organizations around the world.
