I see, I just thought the ip scanner always would find the logger ip since it's plugged into the router.
Problem is. You need IT help with this problem, it is really not easy.
Internet in version IPv4 work with addresses 0.0.0.0 to 255.255.255.255
There are special regions in this pool of addresses:
10.0.0.0 - 10.255.255.255 – (netmask: 255.0.0.0)
172.16.0.0 - 172.31.255.255 – (netmask: 255.240.0.0)
192.168.0.0 - 192.168.255.255 – (netmask: 255.255.0.0)
This range of addresses are for your own private purpose used.
I don't know why but this address 172.* is not used by router, and there is a big problem with this address, because many network devices don't recognize this address as private.
Almost all routers(home network) works with netmast 255.255.255.0 this mean that network 192.168.0.0 is ablsolutely not 192.168.5.0.
192.168.* is ok, but with 10.* now is a party
You have thousands of network to scan.
No problem, because you should scan networks 10.0.0.x, 192.168.0.x, 192.168.1.x, 192.168.16.x, 192.168.100.x + some more.
Routers are made by lazy a**'es. They are almost use 10.0.0.x, or 192.168.0.x
