Is there a way to only filter out certain countries when downloading the IP to Geolocation DB?

You can apply a filter using “grep” if you are only interested in a particular country. Here is an example to do this for the US:

$ curl -L https://ipinfo.io/data/location.csv.gz?token=$TOKEN | gzip -d | cat | grep ',US,' > location-US.csv
$ head -10 location-US.csv
