This property returns a string which identifies the geopolitical
subdivision within a country where the external IP address is located.
In the United States, this will contain the full name of the state or
commonwealth. In Canada, this will contain the name of the province or
territory. These names will always be in English, regardless of the
current system locale.
If a subdivision name does not exist for the location, this
property will return an empty string.
The SubdivisionCode property will return a
standardized abbreviation for the area. For example, in the United
States it would return the two-character code for the state.
