This API was created to help companies identify websites hosted in a specific IP address.
The list of domains that share the same IP address is useful for: threat intelligence and incident response
to discover other possible malicious domains hosted in an IP; threat hunting to search
known bad IP addresses for phishing or malicious domains; discovery of bad neighbors hosted
on the same IP address where is hosted your website.

Domains List

100M+ Domains List

Our database contains 100M+ domains captured from our web services like, these domains are user-submitted and thus were (or still are) online and active, we capture also domains via our internal honeypots that are related to phishing, comment spam and malware.

No Domains Found?

In case our API does not find any domain hosted in the IP address you submitted, it shows an error and your credits are not decreased. This way you pay only in case we find at least one domain in the IP you submitted.

Database Update

Database Update

At the moment we do not automatically update the domain's IP addresses, instead we update a domain's IP address only if the domain IP has been updated on our web services, this means that an user manually requested the update of the domain report on our web service.
