            This is <code>true</code> if the IP address is registered to an
            anonymous VPN provider. If a VPN provider does not register subnets
            under names associated with them, we will likely only flag their IP
            ranges using the <code>is_hosting_provider</code> flag. This key is
            only present when the value is <code>true</code>.
