Also to know is, what does forward and reverse lookup means in DNS?

With a forward DNS lookup, the DNS is queried for the IP address of a certain hostname. A reverse DNS is exactly what you'd expect. It's where the hostname of a certain IP address is queried. Basically, a reverse DNS lookup returns the hostname of an IP address.

Also Know, what is forward lookup zone in DNS? A forward lookup zone is a DNS zone in which hostname to IP address relations are stored. When a computer asks the IP address of a specific host name, the forward lookup zone is checked and the desired result is returned.

Keeping this in consideration, what is DNS discuss DNS forward lookup zone and reverse lookup zone?

Forward Lookup Zones—Forward Lookup Zones allow the DNS Server to resolve queries where the client sends a name to the DNS Server to request the IP address of the requested host. Reverse Lookup Zones—Reverse DNS zones perform the opposite task as Forward Lookup Zones.

What is the difference between a forward lookup zone and a reverse lookup?

The main difference between forward lookup zone and reverse lookup zone is that forward lookup zone is used to resolve forward lookup queries where the client requests an IP address by providing the host name, while reverse lookup zone is used for resolving reverse lookup queries where a client requests a host name by
