Today, we wanted to enter the world of GeoIP, which, as the name suggests, is gleaning information about the “where” of life given an …

  • IP address … known directly … or discernible via a …

$ pip install python-geoip-geolite2
$ pip3 install maxminddb
$ pip3 install maxminddb-geolite2

… and then register with MaxMind after this, to help make this solution happen, but ended up combining the (just) PHP supervision of …

  • ping … means (via PHP shell_exec), as required, to derive an IP address from a host or domain name … then …
  • PHP … means by which MaxMind CSV files are scoured to link IP address to geodata of interest, to derived City and Country of interest information
