How many bytes are contained within an IP address?

• A. 2
• B. 4
• C. 8
• D. 16

Answer: (B)

An IP address, specifically an IPv4 address, is composed of 32 bits. When converting this into bytes, it's important to remember that 1 byte consists of 8 bits. Therefore, to determine the number of bytes in an IPv4 address, you can divide the total number of bits by the number of bits per byte: 32 bits ÷ 8 bits/byte = 4 bytes. This means that an IPv4 address contains 4 bytes. Each byte in the IPv4 address corresponds to one of the four octets typically represented in decimal format (for example, 192.168.1.1), where each octet represents a value from 0 to 255. In contrast, IPv6 addresses, which are becoming more common due to the exhaustion of IPv4 addresses, consist of 128 bits or 16 bytes, which is why other options may suggest a larger number. However, for the specific context of IPv4, the answer is 4 bytes.
