Is it possible to use a public IP from another country's ISP?

[Biggs]

We have a public static IP from a local ISP in country A. It is through an aDSL connection which is "always on" since it's a corporate account and thus, no need to log-in via username and password. If it's currently not in use, meaning, not configured on any NIC, router, etc, can someone at country B "use" it? I mean would the person from country B be able to access the Internet to log-in to a ftp server located in country A. Of course, this would mean that the routes would have to go all the way to country A's gateway then back to country B then back again to country A, correct? Many thanks.

You need to be directly connected to the network that owns the address. For example, in a typical configuration, let's say your other country's IP address is 1.1.1.1, and your local ISP's address range is 2.2.2.2 ..... all of the routers and network belonging to your local ISP is set to route 2.2.2.2 (2.0.0.0 /8)internally, and send everything else outbound to the Internet.

If you want a mini-example, and you happen to be running WIN2K (not sure if Win9X cares) or better, try setting the "Default Gateway" of your computer to some address that doesn't belong on your network.

FWIW

It does not have to be in another country. You will not be able to connect through a different external line even if it is on the same desk.

The Internet signal is fed in the Telco. to the line that it meant to.

As for your public IP, it is like having the car registration and trying to drive it without a car.
