CIDRAM (Classless Inter-Domain Routing Access Manager) is een PHP script ontworpen om sites te beschermen door het blokkeren van aanvragen afkomstig van IP-adressen beschouwd als bronnen van ongewenste verkeer, inclusief (maar niet gelimiteerd tot) het verkeer van niet-menselijke toegang eindpunten, cloud diensten, spambots, schrapers/scrapers, enz. Het doet dit door het berekenen van de mogelijke CIDR’s van de IP-adressen geleverde van binnenkomende verzoeken en dan het vergelijken van deze mogelijke CIDR’s tegen zijn signatuur bestanden (deze signatuur bestanden bevatten lijsten van CIDR’s van IP-adressen beschouwd als bronnen van ongewenste verkeer); Als overeenkomsten worden gevonden, de aanvragen worden geblokkeerd.

Aan het updaten

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.

<p>This plugin is excellent. Have only used for one day and and can tell the difference in garbage traffic on site.</p> <p>Only issue is it is blocking Bing and Google bots at random.</p> <p>Know it is a free plugin, but pretty serious when dealing with important SE bots.</p> <p> </p> <p>UPDATE: Code has drastically improved and can now say impressed with the whole system. Pushing my rating to 5 stars!</p>

CIDRAM helps keep unwanted bots, crawlers, harvesters, spammers etc from taking up precious server resources on my WordPress blog. It is always being kept updated. No annoying or intrusive ads harassing me in my admin panel.
