Cookiebot utilizes a range of different IPs for the different scans we perform. For premium subscription domains, it is an option to have scanning done from a pool of static IP addresses:
Please contact Cookiebot support in order to have static IP scanning enabled for a domain.
These IPs in this article are always up to date, but can subject to change in the near future and can not be considered "fixed" IPs. You can follow this article in order to get notified of any changes we make to the above IP list.
User agent string
To whitelist the Cookiebot scanners or to help filter out Cookiebot from traffic analysis we recommend that you instead do this based on how our scanners identify through their user agent string.
The Cookiebot scanner user agent will look something like this (where X is a numeric value of one or more digits):
Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko; compatible; Cookiebot/1.0; +http://cookiebot.com/) Chrome/X.X.X.X Safari/537.36
As our scanner user agent string will change over time, we suggest simply looking for "Cookiebot" in the string and make your desired configurations based on this.
