This module is available for testing and review.

I'll submit it for review as a proper ZC module shortly. For now it may be downloaded here:

Any feedback, fixes, improvements etc would be appreciated.

Note: banning large geographical areas can possibly have some unexpected consequences. Please be sure you know what you are doing before using this.

This module does not rely on an external geo-ip service.
