The utility will include the following information with every DNS query:

  • Host Name.
  • Port Number.
  • Query ID.
  • Request Type (A, AAAA, NS, MX, and so on).
  • Request Time.
  • Response Time.
  • Duration.
  • Response Code.
  • The number of records.
  • The content of the returned DNS records.

The recorded data can be exported to text, CSV, XML or HTML file, you can also copy and paste it elsewhere (to excel file for example) easily.

System requirements

  • The program runs on Windows 2000 up to Windows 10, for both 32-bit and 64-bit.
  • In some systems, capture does not work properly with ‘Raw Sockets’ for that reason you need to install WinPcap driver or Network Monitor driver, even if capture works fine it is better if you install the drivers to get correct timing information.
  • To use the Network Monitor driver you have to download the 64-bit version of the utility.

How to use DNSQuerySniffer

DNSQuerySniffer does not require any installation or additional files for it to work on your system, all you have to do is download the executable program and run it directly.

When you first run the utility you get a capture options window, where you have to choose the network adapter and the capture method, next time you run the program it will have the same settings, you can change them easily at any time from Options >> Capture options or by hitting F9 in the keyboard.

You can select a number of the queries or all of them to export them to a text or CSV file or copy and paste the quires in the old fashioned way by Ctrl+C and Ctrl+V.
