CIDRAM (Classless Inter-Domain Routing Access Manager) is a PHP script designed to protect websites by blocking requests originating from IP addresses regarded as being sources of undesirable traffic, including (but not limited to) traffic from non-human access endpoints, cloud services, spambots, scrapers, etc. It does this by calculating the possible CIDRs of the IP addresses supplied from inbound requests and then attempting to match these possible CIDRs against its signature files (these signature files contain lists of CIDRs of IP addresses regarded as being sources of undesirable traffic); If matches are found, the requests are blocked.
- PHP >= 7.2.0
Note: CIDRAM does not interact in any way with your database, and stores its own configuration settings, customisations, and related materials as flatfiles within its own directory. If you’ve not changed any of the default configuration settings and if you’re not using any customisations for this plugin, updating normally via the plugins dashboard, without need for any additional steps, should be sufficient and shouldn’t cause any problems. However, if you’ve modified the configuration settings for CIDRAM, or if you’ve made any customisations, I would recommend making backups of all of these prior to updating, due to that updating will overwrite all settings and customisations (after updating, you can then restore your customisations from your backups). Alternatively, if you update via the CIDRAM front-end updates page, all settings and customisations should be preserved.
