A small Windows script that downloads the latest MaxMind GeoIP databases and puts them into a folder called "GeoIP" in your Wireshark user settings directory. The script requires cURL and 7-Zip for downloading and extracting the .mmdb files. Wireshark needs to be configured to use the GeoIP directory in the Name Resolution preferences section.
