AAAA addresses are configured on a host that is not IPv6 aware.
Description
Discussion Text
DNS is only responsible for resolving a domain name to an ip address. Applications and operating systems are responsible for processing the IPv6 or IPv4 record that may be returned. With this in mind, a denial of service could easily be implemented for an application that is not IPv6 aware. When the application receives an i.p. address in hexadecimal, it is up to the application/operating system to decide how to handle the response. Combining both IPv6 and IPv4 records into the same domain can lead to application problems that are beyond the scope of the DNS administrator.
