An A record in DNS stands for "Address" and maps a domain name to the IP address of the computer hosting the domain. It is one of the simplest and most frequently used DNS records. An A record is used to resolve a domain name to the corresponding IP address. When a user enters a domain name in their browser, the A record is used to find the IP address of the computer hosting the domain. Multiple A records can be configured for one domain name, and each A record points to the same IP address. A records are used to enable a "naked" domain address and provide redundancy and fallbacks. The A record is represented by the following customizable elements: Name, TTL, and IP address.
