Probably the IP address belongs to the airport (from which your internet access is coming, since there's no cell signal at the plane's altitude) or to a nearby tower (which might as well be installed in the airport), and the internet connection is just relayed to the aircraft.
Doing some searching around, I found this: How does Wi-Fi work on airplanes?, ...

In order to get this working on a laptop, you'll need to have support "throughout the stack" as follows:
Driver support - The laptop must have hardware drivers that can recognize the GPS device and interface with it, whether it's over USB or some other protocol. The drivers are usually implemented in the kernel, but if you know for a fact that you have ...

Apart from the fact that you need to get your map data somewhere (i.e. over a 3G or WiFi data connection), the current answers miss the most important point:
To obtain your precise location.
GPS is very precise once it acquires lock on enough satellites. However, more often than not, this takes a while, especially with small receivers or in a city (where ...

Core location most definitely supports Bluetooth and USB connected GPS hardware. Although I have not found any Apple documentation for GPS hardware developers, see: Location Awareness Programming, GPS units such as the BadElf and DUAL come with software that pairs the GPS hardware with the iOS device. From that point CoreLocation works transparently. ...

Wi-Fi-based location services work by first compiling a huge database of the geographic locations of various Wi-Fi access points. They key off of the APs' BSSID (wireless MAC address).
Then they keep it up to date by having client devices report the current geo locations of any BSSIDs they see. iPhones update Apple's database, Android phones update ...

You can really only do this if the device can be accessed via Serial or USB.
Bluetooth used to be a common connection type for external GPS devices (before all smartphones got them built in!). In reality what happens is the the Bluetooth drivers expose a virtual USB interface. I'm fairly sure, given that VirtualBox USB support is somewhat sketchy, this ...

Your GPS device is most likely to be connecting to you PC via the Bluetooth Serial Port Profile. This creates a COM port on the host which you should be able to use to communicate with the GPS.
If this is true, it should be pretty trivial to expose the COM port to the virtual machine. VirtualBox has that functionality built in.

Spent too much of my time getting USB to work in virtualbox. It, in my opinion is inherently broken. You will get it to work once, but then it stops. I know this GPS dongle auto detects nicely in almost all OS's http://www.amazon.co.uk/GLOBALSAT-ND-100-Receiver-NetBook-Notebook/dp/B00286KXGU/ref=pd_sxp_f_pt
Experiment with other USB devices in virtualbox ...
