What is the difference between forward and reverse DNS lookup?
Forward lookup zones resolve names to IP addresses and Reverse lookup zones resolve IP addresses to names. Forwarders can be used on your DNS server to forward requests for which your DNS server does not have an authoritative answer.
What is forward 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. They return the fully qualified domain name (FQDN) of a given IP address. For example, a client could send the IP address of 69.163.
What is forward lookup zone and reverse lookup?

What is Reverse DNS PTR?
A DNS PTR record is exactly the opposite of the ‘A’ record, which provides the IP address associated with a domain name. DNS PTR records are used in reverse DNS lookups. A reverse DNS lookup is the opposite of this process: it is a query that starts with the IP address and looks up the domain name.
What is the purpose of a forward lookup?
What is the different between forward and reverse lookup zone?

What is forward zone and reverse zone in DNS?
Why is forward confirmed reverse DNS testing important?
Why Forward Confirmed rDNS is Important – FCrDNS helps prevent others from spoofing your hosts. If I’m the bad guy and I control the reverse lookup for my IP addresses I can put anything in there. I could pretend to be your bank and try to trick you into giving up your account information.
Can a reverse DNS lookup confirm an IP address?
If there is a forward DNS lookup that confirms one of the names given by the reverse DNS lookup, then the FCrDNS check passes. Example: IP address 1.2.3.4 resolves to mail.domain.com. Host name mail.domain.com resolves to IP addresses 1.2.3.4 and 5.6.7.8. Thus, reverse DNS for IP address 1.2.3.4 is forward confirmed.
What does FCrDNS stand for in reverse DNS?
FCrDNS, or Forward Confirmed Reverse DNS, is when an IP address has forward and reverse DNS entries that match each other. For FCrDNS verification, first a reverse DNS lookup is done to get a list of PTR.
What is reverse DNS and what does it do?
Reverse DNS Check. Computer networks use the DNS to determine the IP address associated with a domain name. This process is also known as forward DNS resolution. Reverse DNS lookup is the inverse process of this, the resolution of an IP address to its designated domain name.
