Incomplete question. However, I answered from a general IT perspective.
<u>Explanation:</u>
It is important to note that the internet |(or real internet) in this case, refers to a global network of interconnected networks (internetworks) linked together for the purpose of communication. In other words, it is a broad global network arranged in a mesh network topography form.
It is also important to <em>remember </em>that nobody owns the internet, in other words, it is open an source network. So some internet service providers (ISPs) have a business model where they make revenue by having users pay in other to have the internet service delivered to them.
Answer:
(B) A single public IP address that it can use for NAT
Explanation:
Because the IPV4 IP protocol is still used today, the number of available IP addresses is limited (only 4,294,967,296 addresses in the world), for this reason, the most correct practice is the assignment of a single public IP to those companies that acquire services from an ISP, with some few exceptional cases of companies that own several.
So that the company's addressing can be executed successfully, the use of NATs is enabled, this allows the translation of network addresses, allowing the company to have as many private networks as necessary and that these can be communicated Correctly with the global network, the Internet, through the public IP of the company.
