Show answer & explanation
Correct answer: C
Answer: The four-byte (32-bit) IPv4 address contains both a network portion and a host portion.
Key points:
An IPv4 address is 32 bits long (4 bytes).
The bits are divided into a network portion and a host portion; the split is defined by the subnet mask or prefix length.
Example: a /24 prefix means the first 24 bits are the network part and the remaining 8 bits are the host part.
The network portion identifies the network; the host portion identifies the specific device on that network.
Special notes: when all host bits are zero it refers to the network address; when all host bits are one it refers to the broadcast address.
Therefore the correct statement is that the IPv4 address consists of both network and host addresses; the exact division depends on the subnet mask.
