Legacy APIs

IP Probe

Execute a realtime network probe against an IPv4 or IPv6 address.

This API will run a series of live network scans and service probes to extract useful details about the host provider.

Some of the specific checks this API will perform:

VPN Detection

Scan for VPN software running on the host. This can even identify some private and stealth VPNs

Proxy Detection

Scan for signs of proxy software running on the host. Socks, Squid, Tor, etc

Provider Type

Determine the general type of the IP provider such as 'ISP' or 'hosting'

ASN Lookup

Get the ASN (Autonomous System Number) and other AS details controlling the IP address

Associated Domains

Extracts all the important domain names associated with the IP and ASN

IP Geolocation

Geolocate the physical location of the IP down to the city level (where possible)
Because this API performs live checks against an IP address it can take some time if the target network is slow. In some cases this API may take up to 30 seconds to complete. However on average it will take around 2 to 5 seconds to complete analysis

API Performance
Avg Latency1-60s (variable)This API has a non-deterministic latency based on outside factors
Max Rate10/secondMaximum inbound request rate. Exceeding this will result in request throttling
Max Concurrency250Maximum concurrent/simultaneous requests. Exceeding this will result in error code 06 [TOO MANY CONNECTIONS]
