Troubleshooting Network Connectivity Issues

Learn how to troubleshoot common network connectivity issues using tools like ping, traceroute, and netstat.

Troubleshooting Network Connectivity Issues  

Common Tools  

Using Ping  

Ping tests connectivity between two network devices by sending ICMP Echo Request packets and listening for Echo Reply packets.

ping 8.8.8.8

Ping results show round-trip time and packet loss, which are useful for diagnosing connectivity issues.

Using Traceroute  

Traceroute maps the path data takes to reach a destination by sending packets with incrementing time-to-live (TTL) values and recording the route.

Traceroute results show each hop along the path to the destination and the time taken for each hop.

Using Netstat  

Netstat displays network connections, routing tables, and interface statistics.
