How the IP to Company API Works

This API identifies the name of the organization behind the IP, the type of business (ISPs, businesses, hosting services, or educational institutions), and its domain, using data from internet public records. It looks at an IP range and what organization owns that IP range to determine the affiliated company.

Use Cases

Account-Based Marketing

Track which target accounts are actively engaging with your digital content by monitoring IP addresses linked to those companies, allowing you to measure how well your ABM campaigns are resonating with your audience. Learn more

Personalization and Customization

Identify which companies are visiting your site, then dynamically adjust the content they see. For example, visitors from an educational institution can be shown content highlighting your solutions for their company type, while businesses will see a different set of offerings. Learn more

Fraud Detection

Detect suspicious or unexpected company associations linked to an IP address. If an IP claims to belong to a reputable organization, but the data shows otherwise, cybersecurity teams can respond accordingly. Similarly, the API can detect high-risk or anonymous IPs often used in fraud. Learn more

Sales Targeting

Give your sales team access to real-time data about which target accounts are browsing your website so they can prioritize their outreach to those accounts. For example, if a known high-value prospect company is visiting your pricing page, and you're equipped with the B2B IP data API, the sales team can quickly follow up with a call or email.

We love to integrate with the IPinfo API because it provides us with a highly reliable and accurate stream of data.

Director, CFC

Because our whole system is built around those principles of identification and attribution, we can’t use public information via RIR or other providers. Developing this caliber of data takes a lot of thought and intentional improvement. It’s really quite difficult. There’s a lot of value in having IP data delivered as a service.
