Google Geocode API from China IPv6

When accessing geocode api from our servers in Shanghai, it connects to IPv6, but our provider doesn't support it and requests fails.

However, when accessing from Europe or US, it connects to IPv4 only and works fine.

Here is the output from Shanghai servers

curl -v -IL 'http://maps.googleapis.com/maps/api/geocode/json' 
* About to connect() to maps.googleapis.com port 80 (#0)
* Trying 74.125.128.95... Connection timed out
* Trying 2404:6800:4005:c00::5f... Failed to connect to 2404:6800:4005:c00::5f: Network is unreachable
* Success
* couldn't connect to host
* Closing connection #0
curl: (7) Failed to connect to 2404:6800:4005:c00::5f: Network is unreachable

And this is the output from Europe:

curl -v -IL 'http://maps.googleapis.com/maps/api/geocode/json'
* About to connect() to maps.googleapis.com port 80 (#0)
* Trying 173.194.70.95... connected

If anybody else have this problem, here is a response from google support.

Yes, to access Google Maps from China, use the "ditu.google.cn" domain name instead of "maps.googleapis.com"

For example: http://ditu.google.cn/maps/api/geocode/json?sensor=false&address=Sydney
