DNSQuerySniffer

DNSQuerySniffer is a lightweight Windows tool that allows users to assess information on DNS queries sent to their computer.

It does not require installation, meaning that it is portable and you can just drop the EXE file somewhere on the hard disk and click it to run.

As an alternative, you can save DNSQuerySniffer to a pen drive or other mass storage device, to be able to run it on any PC easily, without installing anything beforehand.

What's more, the tool does not create new entries in the Windows registry or Start menu, leaving it clean after removal. The interface is represented by a normal window with a clear-cut structure, where you can view the host name, port number, query ID, request type and time, response time and code, duration, and total records for each DNS query.

An initial configuration can be made when it comes to selecting the capture method Raw Sockets, WinPcap Packet Capture Driver, Network Monitor Driver and Network Monitor Driver 3.x, in addition to the network adapter and promiscuous mode. These settings can be later changed.

In order to better analyze this information, you can export it to HTML, TXT, CSV or XML format. You can use a search function to look for particular entries, stop traffic capturing at any time, select the time display mode (computer time or relative to capture start), edit font formatting settings, and more.

The tool is very light on the system resources, using low CPU and RAM. It has a good response time and works fine, without causing Windows to hang, crash or pop up errors. Thanks to its intuitive layout and options, DNSQuerySniffer should please all users who want to monitor information on DNS queries.
