It is possible to use GeoIP on Gandi Simple Hosting instances, by recovering the value
X-Country-Code of the HTTP headers .
The value is returned in the form
GB, etc. defined by the ISO norm 3166. You can find the complete list of country codes on the official website https://www.iso.org/obp/ui/
The country code is returned depending on the IP address of the visitor; both IPv4 and IPv6 addresses are supported.
This feature is useful for example in the event that you want to have a website in several languages, where the language is automatically displayed depending on the county of the visitor.
