What is DNS Lookup Tool?

DNS Lookup Tool is a web-based tool that helps you query a domain name and retrieve its corresponding IP address. It is used to translate domain names into IP addresses, which are required for communication between servers on the internet. DNS Lookup Tool provides a simple and quick way to diagnose website issues and identify problems with domain name resolution.

How Does DNS Lookup Tool Work?

When you type a domain name into your browser, the first step in accessing the website is to convert the domain name into an IP address. This is where DNS Lookup Tool comes in.

DNS Lookup Tool starts with the root server, which contains the IP addresses of all top-level domain servers, such as .com, .org, .net, etc. It then queries the appropriate top-level domain server and then moves on to the authoritative DNS server for the domain name in question. The DNS server then returns the IP address, which is used to establish a connection to the website.
