What is the difference between forward and reverse DNS lookup?

Forward Lookup resolves domain to IP and reverse lookup resolves IP to domain. Forward DNS lookup is used to convert the domain name to an IP address format, however reverse DNS lookup works in reverse way to convert IP address to domain name.

How does DNS forwarding work?

Forward DNS works when a user types in the text form of an email address or web page URL. This text is first sent to a DNS server. The DNS server then checks its records and returns the domain’s IP address. If unable to locate the domain’s IP address, the DNS server forwards the request to another server.
