DNSLookupView is a free DNS lookup tool for Windows computers

Computers can only interpret a series of numbers and therefore Domain Name System (DNS) was created to translate web browser’s domains into IP addresses. In this article, we are going to find out about a free DNS monitoring tool DNSLookupView.

How does DNS work?

DNS is a global system used to translate your IP addresses into domain names. When a user is browsing the internet and wants to access a website, the web browser makes a DNS query providing the host name. The DNS server then resolves the hostname to a numeric IP address and connects to your web browser.

What is the DNSLookupView tool

DNSLookupView is a free tool from Nirsoft that gives you detailed information about each DNS query sent through the Windows DNS client service. Details include hostname, request status, request type, request status, request timestamp, request result, ID, and name of the process that requested DNS lookup.

How to use the DNS lookup tool

As the name suggests, this is a tool that monitors DNS queries and gives you detailed information about each query. It’s a fairly straightforward tool and you don’t need any specific technical knowledge to use it. The tool comes in a zip file so you don’t need to install it on your PC. Once you have downloaded and extracted all the files, you can immediately run the application, the executable file – DNSLookupView.exe

It comes with a very user-friendly interface and the main preview has it all. Go to File in the main menu ribbon and click on Start DNS Tracing. You can also press F5 on your keyboard.

The tool works on the Windows Event Tracking feature and takes a few minutes to provide you with the detailed report in one window. You can stop DNS tracing at any time by clicking the red STOP button or selecting Stop DNS Tracing from the File menu or even by using the F6 hotkey.

Once tracing is complete, you can export all DNS queries as HTML reports. You can select the queries manually or select them entirely by pressing CTRL + A. You can also copy and paste them into any of your spreadsheets or save them directly to your PC as a text file.

Other settings options in the DNSLookupView tool include sorting queries by:

  • Host name – The host name, also known as a domain name, is a label assigned to a host computer or any device connected to a network. Host name directs the user to a specific website or web page.
  • Query Type – The DNS client requests information and the DNS resolver provides the response, so the type of information requested is the query type. There are three different types of queries in DNS: recursive query, iterative query, and non-recursive query. When sorting queries by query type, the most common types of queries you encounter include -A (IPv4 address record) and AAAA (IPv6 address record)
  • Request Status – If the DNS Resolver gets the resource code, it displays succeeded if the code is not found, you get the error message. If you choose to sort results by query state, it will show error codes first, then successful queries.
  • Result – This tab displays the results / responses of the queries asked.
  • Process ID – The process ID is the number used by the operating system kernels. This is the unique identifier of the process. If you sort the results by Process ID, it is displayed in ascending order.
  • Thread ID – The thread ID is a unique number generation at the time of thread creation.
  • Process Name – This tab displays the requested processes. Every action a computer takes on data is technically called a process. The process names are displayed in alphabetical order.
  • Process Path – This tab displays the path of the current processes in the DNS Lookup Tool.
  • Time – Here the results are sorted according to the date and time of the running processes.

The tool is available in many different languages, but you need to download the zip file for the appropriate language. The tool is available as a separate zip file for each available language, be sure to download the correct one you want.

You can get all the download links from the official website of Nirsoft.net. It’s a nice, simple, lightweight, and useful utility for tracking DNS queries. Anyone with basic computer knowledge can use it.
