An AAAA record, pronounced "quad-A record," is a type of DNS record that maps a domain name to an IPv6 address, the successor to IPv4. Unlike IPv4, which uses a 32-bit address system, IPv6 utilizes 128 bits, allowing for a significantly larger number of IP addresses. AAAA records are essential for enabling websites to be accessible over the IPv6 protocol, which is increasingly important as the number of internet-connected devices continues to grow and IPv4 addresses become more scarce.
