The IP Module
======================
This module is consuming the global channel.
It first performs a regex to find IP addresses and then matches those IPs to
2019-09-23 18:22:25 +02:00
some configured ip ranges.
The list of IP ranges are expected to be in CIDR format (e.g. 192.168.0.0/16)
and should be defined in the config.cfg file, under the [IP] section
