How many bits are used in an IPv6 address?
- A.
16
- B.
32
- C.
64
- D.
128
Correct Answer
D. 128Explanation
IPv6 addresses are 128-bit long, which is significantly larger than the 32-bit length of IPv4 addresses. This increased length allows for a much larger number of unique addresses in IPv6, which helps to address the issue of IPv4 address exhaustion. With 128 bits, IPv6 can provide approximately 3.4×10^38 unique addresses, ensuring that there will be enough addresses to support the growing number of devices connected to the internet.Rate this question:
