Which of the following is not a function of DNS?

The function of DNS, or Domain Name System, is primarily focused on translating domain names into IP addresses, which allows users to access websites using easy-to-remember names instead of complex numerical addresses. It also plays a vital role in directing web traffic across the internet by resolving domain names to the corresponding IP addresses that identify the servers hosting the websites.

Moreover, DNS enhances efficiency through caching, where frequently accessed domain name lookups are stored for a certain period. This reduces latency by allowing quicker access to these addresses without requiring repeated queries to the DNS server.

Storing website data, on the other hand, is not a function of DNS. Website data, such as files, images, and scripts, is managed by web servers rather than the DNS. While DNS is crucial for locating that data, it does not hold or store the content itself. This distinction clarifies why the correct answer is that storing website data is not a function of DNS.
