Expert
DNS is the domain naming service and is employed for resolving the names to IP address and IP addresses to names. The computer comprehends only numbers while we can simply remember names. Therefore to make it simpler for us what we do is we allocate names to computers and websites. Whenever we use these names the computer utilizes DNS to transform to IP address (number) and it executes our request.
Forward lookup: Transforming names to IP address is termed as forward lookup.
Reverse lookup: Resolving the IP address to names is termed as reverse lookup.
