Hi guys

I can’t really figure this out, so I need some help, please. I’ve read the NMAP network scanning book and some tutorials on Nmap.

My home LAN IP is 192.168.0.1 and using the 192.168.0.1/24 gets me the entire network etc.

But now I want to test my Namp skills on my real IP address. (Gotten from What Is My IP Address? - Lookup IP, Hide IP, Change IP, Trace IP and more... )

But when I scan my real IP address (eg. 123.456.789.0) then I only see my router, but not the rest of my network. (I have 7 devices on my LAN, via Wifi). Why not?

Do this mean that if I secure my router good enough, I’m “home free” for the rest of the LAN? Because I can’t see :

• Which devices are online
• How many are online
• Version detection
• etc

All the examples I have read about is regarding your own network, e.g. 192.168.0.1 or 10.0.0.1, which also works, because I running the scan within the network.

Please help me clarify my confusion about this.

Thanks
