Which record type allows connections to the web server in DNS configuration?

In DNS configuration, the record type that allows connections to a web server is the A record. This type of record maps a domain name to an IP address, which is essential for locating the web server on the internet. When a client tries to access a website, the DNS resolves the domain name to its corresponding IP address using the A record, allowing the connection to be established.

While the other record types serve different purposes, they do not facilitate direct connections to web servers in the same way that an A record does. For instance, an MX record is used for mail exchange, directing email to the correct mail server, while a CNAME record creates an alias for another domain, and a SRV record is used to define services hosted at specific nodes. Each serves a specific function within DNS, but for directly connecting to a web server, the A record is the fundamental mechanism employed.
