# IP Info 0.1 - Simple wrapper for ipinfo.io api
#
# I deliberaltely limited the current options at the ones that
# don't require an api key but more will be added in the future
# With the ability to use a token which will give an access
# to a set of more advanced features proposed by ipinfo.io
#
# Especially the possibility to use a more fine-grained filtering,
# or to use their 'batch' system which allows to send up to 100
# ip address in only one POST request. Instead of having to send
# them one by one like in the current implementation.
