What are anonymous IP addresses?

Anonymous IPs hide a user's actual IP address, masking their geographic location. While there are valid reasons to use anonymous IPs for privacy and security, malicious actors exploit anonymous IPs to circumvent regulations or commit fraud—causing significant challenges for businesses.

Types of anonymizers flagged

Anonymizing VPN services

These are IP addresses registered to known services that offer users a tunnel to a VPN server, which serves to hide the true IP address.

Residential proxies

These are IP addresses on a suspected anonymizing network that are registered under residential ISPs (does not include peer-to-peer proxy IPs).

Hosting providers/data centers

These are IP addresses associated with hosting services that are likely to be used as anonymizers. This anonymizer type also includes both registered and non-registered anonymizing VPN services.

Tor exit nodes

These are IP addresses from which Tor users will access the internet. The Tor Project is an open network used by those who wish to maintain anonymity.

Public proxies

These are proxies that are available for free and publicly posted.
