How many connections is a application making from your PC to external sites? How many open connections are currently active from your PC to external sites? How many external sites are accessing your PC?

These set of questions are pretty hard to answer unless you are pretty familiar with tracking your network connections, there are tools that allow you to monitor bandwidth usage ^[1], but those apps do not show you detailed information.

Axence NetTools Pro is a handy freeware ^[2] and all-in-one network monitoring tool, that will help you answer the above questions with ease, you can use the tool to monitor all your incoming and outgoing connections.

The tools provides users with the following network monitoring features;
