The filter cross-checks all of your app installs and reattributions with MaxMind’s anonymous IP database. Any user affiliated with an anonymizing service is attributed to an isolated tracker called “
Untrusted Devices”. This helps prevent the majority of fraud associated with simulators before it begins, and reduces the impact of data center manipulation tactics significantly.
To set up the anonymous IP filter, follow these steps in the Adjust dashboard.
- Find your app and select your app options caret (^)
- Select All Settings > Fraud Prevention
- Switch the ANONYMOUS IP FILTERING toggle ON
Anonymous IP” tracker - a subtracker of the network-level tracker Untrusted Devices. You can also use the following KPIs to view rejected installs and reattributions by traffic source.

|Rejected reattribution: anonymous IP (RR AIP)|
To view your statistics, follow these steps in the dashboard.

VPN stands for virtual private network. One function of a VPN is to allow a user to connect to the internet through an IP address that is not their own. VPNs allow users to circumvent geo-restricted websites and services, as the IP address can come from anywhere in the world. Fraudulent publishers use VPNs to make it seem as though installs are coming from more lucrative countries.
Tor exit nodes
Tor is a service that directs traffic through a global network of servers to anonymize users’ identities. Each server is called a node, and Tor encrypts traffic as it bounces it through the nodes. Encrypted traffic reaches the internet through a Tor exit node. Tor traffic has the IP address of the Tor exit node it left through.
As with VPNs, Tor provides more anonymous access to the internet. Fraudsters take advantage of this to make it seem as though their fake installs are coming from disparate locations.
The data centers on MaxMind’s list are not affiliated with an internet service provider (ISP). This means that any user activity originating from these data centers is either artificial or has been rerouted. Typically, fraudsters that run large numbers of simulators rely on these data centers to provide the computing resources for their illegal activities.
