An interviewer will ask you this question to understand your technical knowledge and see if you know some of the more detailed aspects of the technology you support. While many technical support engineers may be familiar with DNS, many may not understand the subtle difference between reverse and forward lookup. Knowing small details like this will differentiate you from other candidates and qualify you for this role.

"The purpose of DNS is to resolve the IP addresses users are trying to reach. Typically, users will type in the name of a website using the familiar 'WWW.' format. The DNS server will then identify the correct IP address for the website or server and connect the user to it. Converting the names the user types into the appropriate IP address is called a forward lookup. A reverse lookup occurs when the user types the actual IP address, and then the DNS server resolves the name of the website or server."
