Reverse and Forward DNS lookup

DNS lookup

In small terms I found that it is the process which is initiated by a device which is connected to a DNS server say your personal computer which you use at your home which is connected to the internet, when you type a website address in your web browser chrome, firefox or whatever, that domain name is sent to a DNS server to lookup its corresponding IP. Process of looking in a DNS server for particular IP or Domain name can be called as DNS lookup. There are 2 types of DNS lookup, Forward DNS lookup and Reverse DNS lookup.

Forward DNS lookup is the process of looking for an IP address of a specific domain name in a DNS server.
Reverse DNS lookup is the process of looking for a domain name of a specific IP address in a DNS server.
