Route 53 is a managed Domain Name System (DNS) service provided by Amazon Web Services (AWS) that is used to translate domain names into IP addresses.
IPv6 is the latest version of the Internet Protocol that uses 128-bit addresses, which are longer than the 32-bit addresses used in IPv4. The AAAA (pronounced "quad A") record type is used to map a domain name to an IPv6 address.
The A record type is used to map a domain name to an IPv4 address. The CNAME (Canonical Name) record type is used to map an alias name to the canonical name of a domain, while the PTR (Pointer) record type is used in reverse DNS to map an IP address to a domain name.
Therefore, the AAAA record type is used for IPv6 addresses in Route53.
