An IPv4 address consists of how many ______-bit octets?

An IPv4 address consists of four octets, with each octet being 8 bits in length. Therefore, the structure of an IPv4 address can be understood as a 32-bit number, which is divided into four segments, or octets. Each octet can range from 0 to 255, allowing for a wide range of unique addresses. The configuration of these four octets is fundamental to the addressing scheme used on the internet and is critical for identifying devices within a network.

The other options do not align with the standard structure of an IPv4 address. An IPv4 address has been defined explicitly as containing four octets, rather than six, eight, or ten, making the understanding of its format essential for networking concepts, troubleshooting, and configuring devices.
