MyDNSMon is an advanced tool designed to monitor DNS queries and responses. It provides a comprehensive view of every detail in the DNS packet, allowing you to analyze and debug DNS issues quickly. You can customize the level of detail you want to view, whether you need a high-level overview or a detailed analysis of each query and response.

In addition to displaying information on the screen, MyDNSMon allows you to write basic source, destination, query, and response fields to a CSV file. This file can be used to analyze the data later and gain insights into DNS activity across your network.

With MyDNSMon, you can ensure the security and stability of your network by monitoring all DNS activity. Whether you're a network administrator, a security analyst, or a developer, MyDNSMon is a valuable tool that can help you troubleshoot and optimize your DNS infrastructure.

Before using MyDNSMon, ensure you have installed the latest version of https://npcap.com. Then, select the network interface you want to listen on and press CTRL + C to stop MyDNSMon.
