I'm able to access router panel on 192.168.100.1, although I don't see such network in ipconfig [closed]

I am able to access the router's administration panel at http://192.168.100.1/logon.html.

ipconfig returns this:

$ ipconfig

How am I able to access 192.168.100.1 if there is no such network returned by ipconfig? Why I don't see that network?

Solution 1:

That's the WAN interface on your router. You can get to it because the traffic goes to your Default Gateway, which is the router.
