This plugin will check for changes in CloudFlare's IP ranges. So, if you have a website behind cloudflare and you filter the source IPs on your firewall, you'll know if there are any new IP ranges (both IPv4 and IPv6) so you can update your firewall.

This plugin maintains state (meaning the "original" IP ranges from cloudFlare) in files. If they don't exist at first execution, the plugin will create them by getting the cloudflares IP ranges and will report everything as being OK.

If there are any changes (new IP ranges), this plugin will send a Critical status to Nagios.

The reading to check cloudflare's IP ranges is done through HTTPS and it won't work if the certificate is not validated.
