Which protocol provides a nearly unlimited number of Internet Protocol (IP) addresses?

• A. Transmission Control Protocol (TCP)
• B. Internet Protocol version 4 (IPv4)
• C. Internet Protocol version 6 (IPv6)
• D. Hypertext Transfer Protocol (HTTP)

Answer: (C)

The correct answer is Internet Protocol version 6 (IPv6) because it was specifically designed to address the limitations of its predecessor, Internet Protocol version 4 (IPv4), particularly concerning IP address availability. IPv4 has a limited address space, providing approximately 4.3 billion addresses, which has become insufficient due to the exponential growth of devices connected to the Internet. In contrast, IPv6 offers a vastly expanded address space, theoretically allowing for 340 undecillion unique addresses (that’s 3.4 x 10^38), which is far more than what is practically needed for any current or foreseeable future applications. This extensive pool of addresses is crucial for supporting the increasing number of devices, such as smartphones, tablets, IoT devices, and computers, ensuring that every device can have a unique IP address. The other protocols referenced in the options serve different purposes. Transmission Control Protocol (TCP) is a transport layer protocol that ensures reliable transmission of data across networks but does not provide IP addresses. Hypertext Transfer Protocol (HTTP) is an application layer protocol used for transferring hypertext requests and information on the web, and it also does not address IP allocation. Internet Protocol version 4 is limited in its address space, which is the primary
