The ip address (10.1.1.10 above) is that of your computer - or more
exactly of that particular interface: ethernet?

If you had run that command *on the router/modem*, then indeed it would
suggest that was the address (of one of its interfaces). But you ran it
on your computer, so it is telling about that.

Above 192.168... seems weird unless it is the factory default
setting for your router/modem.

So that confirms that the router/modem has the local interface
bound to 10.1.1.1.

I don't understand why you are using an alien op system when you
have far more powerful tools at your disposal under linux. Maybe
you are just moving away and are used the the old ways?`

All just what is expected: the router/local LAN port is 10.1.1.1 .

You are pointing back at yourself, and presumably you are not running
an http server like apache, or it is configured only to respond to local
requests.

I suspect that "bridging mode" is your whole problem. But I may be 
wrong. Can others comment?

That just confirms what I said above. You might want to look at
ipconfig eth0 as well, just for interest. Again, you may need to be
root (sudo, etc).

As I say, I suspect that you should not be using bridging mode...
