GeoSniper

This module provides a geo-location block for your Drupal site, which displays to your visitors their:

• IP address
• Internet Service Provider's Name
• Telephone Area Code
• City
• State
• Zip/Postal Code
• Country's flag
• Country's Name/Code
• Latitude
• Longitude
• DMA Code (kind of "optionally"... if enough people say that they care to have that feature then I'll commit it but otherwise I'll leave it as is for now)
