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
