What is a domain name? How do domain names work?

A domain name is a unique address used to access a website, like google.com or wikipedia.org. It's a string of text that maps to an IP address, which is the numerical label assigned to each device connected to the internet. Domain names are used to identify one or more IP addresses, making it easier for people to remember and access websites without memorizing complex numbers.

Forward and reverse DNS lookups: What they are, why you need them, and how to configure them

Effectively managing the dynamics of domain name lookups through the DNS is crucial for boosting the speed and security of network connections.

In a DNS, a zone refers to a specific segment of the domain namespace, such as clouddns.manageengine.com or manageengine.com, where each segment can be a unique zone, including top-level domains, like.com. DNS servers translate domain names into IP addresses, assigning a specific IP to each zone as an authoritative response, representing network participants like services or hosts.
