Question

The size of IP address as per IPv6 protocol is :

• A. 64 bits
• B. 32 bits
• C. 128 bits
• D. 256 bits

Answer 1

Answer:

C. 128 bits

• The size of an IP address as per the IPv6 protocol is 128 bits.

• This is a significant increase from the 32-bit addresses used in the previous version, IPv4.

• The change was necessary to accommodate the massive growth of the internet and the ever-increasing number of devices that need a unique address.

• A 128-bit address space provides an astronomically larger number of unique addresses compared to the 32-bit IPv4 space.
