public address using the fully qualified domain name. Which of the following IP settings should be
verified?

Explanation:
On the Internet, the Domain Name System (DNS) associates various sorts of information with socalled domain names; most importantly, it serves as the “phone book” for the Internet: it translates
human-readable computer hostnames, e.g. www. Certkiller .com, into the IP addresses that
networking equipment needs for delivering information.
