Final answer:
An AAAA record is commonly used to route traffic to an IPv6 address.
Step-by-step explanation:
The correct answer is C. An AAAA record.
An AAAA (pronounced quad-A) record is used to route traffic to an IPv6 address. It is the IPv6 equivalent of an A record in IPv4.
For example, if a user enters a domain name into their web browser, the AAAA record is used to retrieve the corresponding IPv6 address, which allows the browser to establish a connection to the website.
