|
||||
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
|
||||
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
