CLI:Basics Networking – Checking IP, Testing Internet with Ping
Congratulations — you’ve reached the final lesson of CLI:Basics!
By now, you have enough command-line skill to be comfortable working with Linux at a basic but real-world level.
Today, we’re wrapping the series by looking at basic networking troubleshooting commands — simple but powerful tools you’ll use all the time.
Let’s jump in:
🌐 Checking Your IP Address with ip
- Show full IP information:
ip address show - Simplified (shortcuts work!):
ip a - Add color for easier reading:
ip -c a
What you see:
- Local loopback address (
127.0.0.1) - Ethernet adapter IP (ex:
192.168.x.x) - Wireless adapter info (if present)
- MAC addresses and IPv6 addresses
📡 Testing Internet Connection with ping
- Ping a public IP (Google DNS):
ping 8.8.8.8 - Ping a website by name (testing DNS resolution): bashCopyEdit
ping google.com
Important differences:
- Linux: Continuous ping by default (Control+C to stop)
- Windows: Pings 4 times unless you specify otherwise
Optional: Limit the number of pings:
ping -c 3 google.com
