Were it so easy. I have two PCs connected thru a TCP/IP LAN, one of them
with an Internet connection, the second also indirectly connectable by means
of Vsocks, a proxy server/client & firewall. Vsocks can be configured for a
dual connection or a single, any of the PCs in the LAN (though the one with
the Internet connection is always connected, whether you spawn an Internet
app or not.

This means that, for example, in the PC with the actual, physical
connection, I maintain an IP address of  192.168.1.1 (subnet mask
255.255.0.0), whether I'm online or not. Since obviously my ISP will assign
me a dynamic address while I'm online, at this moment my IP address is
"192.168.1.1, 200.42.140.20"

I've also used GO Express Search, a downloadable metacrawler that queries in
the background, so every result you get to view doesn't appear to come from
the Internet but from localhost (port 1234).

So, how to test whether online or not? Basically I agree with Kat: try
something, then test the results. However, I would take this as conclusive
only if you get a positive. A negative I would interpret only as meaning I
didn't get a result, not that I wasn't online. Too many times I've had my
ISP hang on me for several minutes, then restarting at their discretion.
