To translate domain names into IP addresses.
The function of the Domain Name System (DNS) can be summarized in three points:
1. To ensure that each IP address has only one corresponding domain name: DNS helps to maintain a unique mapping between domain names and IP addresses. This means that when a user enters a domain name in their web browser, DNS ensures that the correct IP address associated with that domain name is retrieved and used to establish a connection.
2. To translate domain names into IP addresses: DNS acts as a phone book of the internet by translating human-readable domain names (like www.example.com) into machine-readable IP addresses (like 192.168.1.1). This translation allows computers to communicate with each other using domain names instead of memorizing complex numeric IP addresses.
3. To facilitate the assignment of unique domain names: While DNS itself does not assign unique domain names to every computer, it provides the framework for registering and managing domain names. When a new domain name is registered, DNS allows it to be assigned to a specific IP address, ensuring that requests for that domain are properly routed to the correct server.
The correct answer is:
To translate domain names into IP addresses.
Explanation: The function of the Domain Name System (DNS) is to translate human-readable domain names (such as www.example.com) into machine-readable IP addresses (such as 192.0.2.1). This translation is necessary because computers communicate with each other using IP addresses, while domain names are more user-friendly and easier to remember. The DNS acts like a phonebook, allowing computers to look up the IP address associated with a given domain name. By doing so, the DNS enables internet users to access websites, send emails, and perform other online activities using domain names rather than having to remember the corresponding IP addresses.
