What is a Bulk IP Lookup?

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.

Frequently asked questions

  • What is IP geolocation?

    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.

  • Why is checking IP addresses in bulk convenient?

    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.

  • Who can use bulk IP lookups?

    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.

  • How does your bulk IP lookup tool work?

    IP Geolocation Bulk 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.

  • How often do you update IP data?

    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.
