Our IP privacy detection data is supported by active measurement and behavior-based detection, making it the best-in-class VPN and proxy detection service available.
However, users who regularly use our data through our free tier are interested in getting access to our privacy detection data at an affordable rate. So, we have decided to make a portion of the data accessible for an affordable price through our updated Core API service, which is our most basic paid tier.
The Core API service includes what we refer to as network flags. Network flags provide binary responses regarding the nature of IP addresses. Currently, we offer five different network flags through the Core API service.
is_anonymous: Indicates whether the IP address is anonymous.trueif the IP address is associated with an IP privacy service, such as a VPN, proxy, Tor, or relay. This provides a high-level summary flag from our IP to Privacy API response.is_hosting: Indicates whether the IP address is an internet service hosting IP address. This information is separately derived from our IP to Privacy data.is_anycast: Indicates whether the IP address is an anycast IP.trueif the IP address maps to multiple physical servers in different locations via anycast routing.is_mobile: Indicates whether the IP address belongs to a mobile network.trueif the IP address is associated with a cellular network, carrier, or mobile device. This information is from our carrier IP API service.is_satellite: Indicates whether the IP address is part of a satellite internet connection.trueif the IP address belongs to a satellite internet pool.
Now, let’s take a look at the is_anonymous and is_hosting flags in particular as they relate to our IP Privacy Detection data.
