What does a domain name, such as reddit.com, specify?

A domain name, such as reddit.com, specifies the server supporting a website. In the context of the internet, a domain name serves as a human-readable address that maps to an IP address, which is what computers use to identify each other on the network. When you enter a domain name into your web browser, it performs a DNS (Domain Name System) lookup to find the corresponding IP address of the server hosting the website associated with that domain name.

This means that the primary function of a domain name is to indicate which server will respond to requests for access to the website, effectively pointing users to the correct destination on the internet. The other options do not capture this essential role; for instance, while a domain name might suggest a type of content or a database, it does not inherently specify these things. The domain itself does not indicate how content is hosted, nor does it directly specify any hosting method used by that server.
