What is DNS Resolver?
A DNS resolver, also known as DNS recursor and commonly referred to as "DNS lookup" tool, is a DNS server that resolves an individual hostname to an IP address.
Usually, the resolver is one part of a larger decentralized DNS (domain name system). When a client sends a request to the DNS resolver, the resolver accesses other servers in the DNS to obtain the address, then sends the response.
For example, when a user types in a URL ("manageengine.com") in their web browser, that URL is given to the DNS resolver. The resolver then examines its cache memory to see whether the IP address for the URL is already stored. If the IP address information already exists, the resolver will send the IP address to the browser. The user is then able to see the website for which they typed in the URL.
