How to find your network IP information
Sometimes you need to find your network information or the IP address of your computer, for this we can use IP/IF Config on most operating systems
Windows​
Go to command prompt and type "ipconfig"
Mac​
Go to terminal and type "ifconfig"
Linux​
- Open a terminal emulator window.
- Type the following command to access the Network Namespace subsystem: sudo ip netns
- You'll see a list of network namespaces. Choose one arbitrarily (let's say ns1).
- Enter the chosen namespace: sudo ip netns exec ns1 bash
- In the new shell, run the following command to list all network interfaces: ip addr show
- Find the interface you're interested in. Note its name (e.g., eth0).
- Use tcpdump to monitor traffic on that interface:
- sudo tcpdump -i eth0
- Now, you'll see a stream of network packets. Look for IP addresses in the packets. This might require some parsing if the output is extensive.
- When you find an IP address of interest, you can stop tcpdump by pressing Ctrl + C.
