The Domain Name System (aka DNS) is used to resolve human-readable hostnames like www.Dyn.com into machine-readable IP addresses like 204.13.248.115.

Forward lookup zone is to convert from domain name to IP addresses and Reverse lookup zone is to convert from IP addresses to domain name.

he Domain Name System (DNS) is a central part of the Internet, providing a way to match names (a website you're seeking) to numbers (the address for the website). Anything connected to the Internet - laptops, tablets, mobile phones, websites - has an Internet Protocol (IP) address made up of numbers.

DNS Domain name system provide a standard method for associating names with numeric internet addresses.This makes it possible for users to refer to network computers by using easy to remember names instead of a long series of numbers. In addition DNS provides a hierarchical namespace ensuring that each host name will be unique across a LAN or WAN.

Forward lookup zone maps an IP to a host name.

Reverse lookup Zone:Maps hostnames to IP

Domain naming server is doing conversion of Ip address to FQDN and FQND to ip address. If we convert IP to FQDN it is called Forward lookup zone. If we convert FQDN to ip address is called reverse lookup zone
