What is the standard length in bits of an Internet Protocol version 4 (IPv4) address?
Answer and explanation
Correct answer: C. 32 bits
- Step 1: An IPv4 address consists of 32 binary bits divided into four 8-bit octets (e.g., 192.168.1.1). Step 2. This creates an address space of 2^32 ≈ 4.29 billion possible addresses. Answer: 32 bits. Why not the others: 128 bits is the size of an IPv6 address; 64 bits and 16 bits do not correspond to standard IP addressing lengths.
