A Records are a type of DNS (Domain Name System) record that maps a domain name to its corresponding IP address. This allows web browsers to locate and connect to websites using human-readable names instead of numerical addresses. For example, when you type in www.example.com, the A Record helps direct your request to the correct server. A Records are essential for the functioning of the internet, as they ensure that users can access websites easily. Each A Record typically contains the domain name and the associated IPv4 address, which is a series of four numbers separated by periods, like 192.0.2.1.
