What format is an IPv4 address expressed in?

• A. Six groups of 8 bits
• B. Four groups of 8 bits
• C. Eight groups of 16 bits
• D. Two groups of 32 bits

Answer: (B)

An IPv4 address is expressed in a format consisting of four groups of 8 bits each, which is also commonly referred to as "octets." Each octet can represent a decimal value ranging from 0 to 255, based on its binary representation, which aligns with the idea that each group consists of 8 bits. This structure allows for a total of 2^32 possible unique addresses in the IPv4 addressing scheme, enabling the system to uniquely identify devices on a network. The other formats presented in the choices do not conform to the standard definition of IPv4 addresses, as they either combine groups incorrectly or misrepresent how bits are grouped and used in the addressing scheme.
