Why should you monitor network traffic on your Windows device? To explain this, imagine yourself as the network administrator in your office. Are you getting huge traffic that is impacting your network performance? If the answer is yes, you should figure out who or what is sucking up your bandwidth. 

Sometimes the solution will be to get extra bandwidth to manage your network. However, in most cases, the network is not optimized correctly, which harms the performance.

To find the culprits causing the problems, you will need to analyze the network for the problem. Many tools are available online to do just that, but each tool comes with its own set of advantages. 

These tools will help you identify the root causes of the network bottlenecks by monitoring network traffic coming and going from your system. By controlling the network traffic, you can get the most out of your present bandwidth, allowing you to respond to any issue efficiently. 

You can use Network Traffic analyzer tools to record and analyze the application’s traffic, users, and IP address. It checks for network availability and identifies network anomalies. Since there are many tools out there, it’s crucial that you choose the right one to cater to your business requirements. 

Here's the solution if you would like to know more about dedicated IP addresses. Read more
