A bulk IP lookup, also known as a batch IP lookup, is a type of query done to check the location, ISP, AS details, linked domains, Internet connection, time zone, and other data points of a large number of IP addresses simultaneously.
Harness the power of geo-targeting by catering to the right audiences aided by a robust IP lookup tool. Locate your best markets and tailor your marketing campaigns and strategies to them.
Improve the performance of security solutions and systems by adding IP geolocation data to your threat intelligence sources. Pinpoint known threat sources and block them at the IP level if you have to before they can cause damage.

Enrich your traffic logs and monitoring systems with IP location data to meet regulatory requirements and prevent transactions with designated countries.
IP geolocation points to the nearest-known physical location where a specific user currently is based on its IP address. Subjecting an IP address to an IP geolocation lookup provides a user’s country, region, city, latitude and longitude coordinates, time zone, GeoNames ID, AS details (AS number, ISP, route, domain, and type), and Internet connection type, among other data points.
Organizations typically keep track of both incoming and outgoing network traffic. And that translates to hundreds or even thousands of domains and IP addresses per day. Checking them out one by one may be time-consuming and prone to human error. That’s what makes batch IP lookups convenient.
Bulk IP lookups are helpful to any organization that wants to keep track of website visitors and users. They are also useful for those who want to prevent fraud, comply with strict area-specific requirements, and keep malicious IP addresses out of their networks. They can also be valuable to advertisers who rely on geo-targeting and geofencing.
Bulk IP Geolocation GUI works similar to our IP geolocation lookup tool. Unlike the latter, though, our bulk IP lookup tool can take as many as 100,000 IP addresses as input per query. You can either copy and paste the data into the input field or upload a comma-separated values (CSV) file to the tool and get the results in CSV format after in minutes.
Our IP geolocation data gets updated daily. That means you get the latest location information available every day, which can be particularly important when you’re investigating specific IP addresses. Since ISPs have a limited number of IP addresses, and these typically are assigned based on availability, users’ IP addresses can change from time to time. As a result, they can get any of the providers’ unused IP addresses at the time they’re accessing the Internet. Therefore, having up-to-date information regarding a particular IP address can be crucial.
“ We’ve used WhoisXML API’s data in our own investigations, and it is one of the most popular integrations among Malfors users. It is the best source we’ve found for WHOIS data, including WHOIS history and Reverse WHOIS. Analysts can pivot on DNS records or WHOIS text to uncover more infrastructure and support threat actor attribution. Our users, from SOC teams to incident responders, can access that data in just a few clicks. ”
“We want to provide all Cyberscape users the ability to integrate relevant data for their cyber threat investigations. WhoisXML API provides unique data that will be helpful to the cyber threat investigation community, allowing analysts to shorten the cycle of understanding and mitigating threats.”
