Which logical addressing method is widely used throughout the public Internet?

• A. Internet Protocol version 2 (IPv2)
• B. Internet Protocol version 4 (IPv4)
• C. Internet Protocol version 6 (IPv6)
• D. Internet Protocol version 8 (IPv8)

Answer: (B)

The widely used logical addressing method throughout the public Internet is Internet Protocol version 4, or IPv4. This protocol facilitates the identifying and locating of devices on a network by assigning unique numeric addresses to each device. IPv4 utilizes a 32-bit address scheme which allows for approximately 4.3 billion unique addresses, and this system has been foundational in establishing the structure of the Internet since its inception. IPv4 addresses are typically expressed in a decimal format divided into four octets (e.g., 192.168.1.1), making them manageable and easy to understand for network administrators. Despite growing limitations due to the exhaustion of available IPv4 addresses, it is still heavily utilized for most Internet traffic, as many systems and web services are designed to support it. While other versions like IPv6 and IPv2 exist, they have not been as broadly adopted as IPv4 for Internet addressing. IPv6 was developed to address the limitations of IPv4, specifically regarding the number of available addresses, but uptake has been gradual, and IPv4 remains the standard in most public Internet uses today. As for IPv8, it is not a recognized version of the Internet Protocol.
