The AAAA record is used in DNS to map a hostname to its corresponding IPv6 address, which is necessary for routing to the correct network address in an IPv6 environment. The A record is used for IPv4 addresses, not IPv6. The CNAME record is used for aliasing and does not provide IP mapping. The MX record points to the mail servers handling email for the domain and does not involve direct IP address mapping. TXT records are used for providing arbitrary text about a host or other metadata associated with a domain. NS records identify DNS servers responsible for the domain, not the IP addresses of the hosts within the domain.
