IPv6 is not the protocol used most for communications over the Internet.

• A. True
• B. False
• C. Cannot determine
• D. Depends on the network

Answer: (A)

IPv4 is still the backbone of most Internet communications. IPv6 was created to address address exhaustion and to offer other improvements, but transition has been slow and gradual. Many networks run dual-stack systems that support both IPv4 and IPv6, and NAT lets many devices share a single IPv4 address, reducing the immediate need to switch entirely to IPv6. As a result, the majority of Internet traffic continues to travel over IPv4, making the statement true. Adoption of IPv6 is growing, but it has not yet surpassed IPv4 across the Internet as a whole.
