The return values are not really documented anywhere in a straight-forward fashion.
The best I could find is a list of all countries and their associated continent codes, here: http://www.maxmind.com/app/country_continent
Leaving us with 7 possible continents:
AS for Asia
EU for Europe
SA for South America
AF for Africa
AN for µAntartica
OC for Oceania
NA for North America
As mentioned above, if the host/IP is not found in the database, the function returns FALSE.
