A Record
A DNS record that maps a domain name to an IPv4 address.
An A record (Address record) is the most fundamental type of DNS record. It tells the internet which IPv4 address to connect to when someone types your domain name into a browser. For example, an A record for example.com might point to 93.184.216.34. Without an A record, browsers would not know where to find your website. Every website that is reachable by its domain name has at least one A record (or an AAAA record for IPv6).
