Device verification

The device verification APIs probe a device's IP address, blocklist information, host reputation and user agent.

The IP probe runs live network scans and service probes. Among the checks it performs:

• VPN detection: scans for VPN software running on the host, including some private and stealth VPNs.
• Proxy detection: scans for signs of proxy software such as SOCKS, Squid and Tor.
• Provider type: determines the general type of provider, such as ISP or hosting.
• ASN lookup: returns the autonomous system number and other AS details for the IP address.
• Associated domains: extracts the important domain names associated with the IP and ASN.
• IP geolocation: locates the IP down to city level where possible.
