What system is responsible for tracking and regulating Internet names and addresses?

The Domain Name System (DNS) is the correct answer because it is specifically designed to manage and regulate Internet names and addresses. DNS functions as the phonebook of the Internet, translating human-readable domain names (like www.example.com) into numerical IP addresses that computers use to identify each other on the network. This system allows users to access websites easily without needing to remember complex series of numbers associated with each website.

In contrast, while Information Technology Systems generally encompass a range of technologies used for processing and managing information, it does not specifically focus on the regulation of domain names and addresses. Similarly, the term Cyberspace System is vague and not technically applicable to the management of Internet names and addresses, as it refers more broadly to the virtual environment encompassing the internet. The Internet Service System is also not directly involved in tracking domain names; it typically refers to the services provided by Internet Service Providers (ISPs) that facilitate access to the internet.
