Networking Fundamentals — Question 55

How many bits are there in an Internet Protocol version 6 (IPv6) address?

Answer options

• A. 32
• B. 64
• C. 128
• D. 256

Correct answer: C

Explanation

An IPv6 address is composed of 128 bits, which allows for a vast number of unique addresses. The other options, 32, 64, and 256 bits, do not represent the correct size of an IPv6 address and correspond to other protocols or theoretical limits.
