Each hop is denoted with an IP address and round-trip time (RTT), which indicates the time taken for data packets to travel between your computer and that particular hop.
By examining the tracert results, you can identify any problematic hops with high RTT or request timeouts. This information can be vital in troubleshooting network issues, such as network congestion or faulty routers along the route. Armed with this knowledge, you can take appropriate action to resolve the problem and optimize your network connectivity.
Monitoring Network Performance: Utilizing The Netstat Command
The netstat command is a powerful tool that allows you to monitor your network performance by displaying active connections and listening ports on your computer. This is particularly useful for identifying any suspicious or unauthorized network activity.
To use the netstat command, open the Command Prompt and type “netstat” followed by the desired options. Some commonly used options include “-a” to display all connections and listening ports, “-n” to show the IP addresses and port numbers in numerical form, and “-b” to display the executable involved in creating the connection.
By analyzing the output of the netstat command, you can identify which programs or services are accessing the internet, the protocols being used, and the specific IP addresses and port numbers involved. This information can help you identify any unwanted or suspicious connections, as well as potential bottlenecks or performance issues within your network.
