Frequently Asked Questions

An ASN is a globally unique identifier assigned to an autonomous system, a network or group of networks under a single organization's management that has a defined routing policy.

Yes, you can perform an ASN lookup for any IP address using our service. It provides details such as the associated ASN, the organization that owns it, and the IP ranges linked to that address.

Yes, we offer an ASN Lookup API providing detailed information such as the ASN number, organization name, IP ranges, routing data, peers, upstreams, downstreams, domain, allocation status, and WHOIS response.

We update our ASN dataset on a daily basis, collecting data from reliable sources to ensure accuracy and reliability.

Autonomous Systems use BGP to advertise IP prefixes and exchange routing information between routers, peers, upstreams, and downstreams. This enables efficient connections and data flow across interconnected networks and the global internet infrastructure.

Our database includes the ASN number, associated organization's name, country of registration, announced IP routes, domain, peering details, and allocation status.

Yes, we offer a free ASN lookup tool that allows you to perform lookups with a limited number of requests. It's perfect for basic queries and getting started with ASN insights.

Our Customers Say

We were looking for a solution that allows us to get the necessary information by ip-address. It was important for us to find local database, because our clients are banks that don't prefer to share their personal data. These guys quickly answered all our numerous questions before we stopped looking for a suitable solution. Special thanks to Rameez for all his efforts. We really hope for our long-term cooperation and wish your team success. Your approach to customers deserves respect.

In other services, we have been using in the past to geolocate the IP addresses but the problem always was the unreliable data, out of sync geolocation databases but with IPGeolocation this problem is now a thing of the past. We rarely get any issue of outdated data and in for the last 1 year, we have been using this service only 3 or 4 IPs were wrongly geolocated and believe me we check for thousands of IPs every month.

We worked with the ipgeolocation team, the team was super helpful, knowledgeable and the tool is easy to integrate. We have had no problem since we last enabled ipgeolocation. We are seeing incremental traffic directed to the right country, as a result, the volume has increased in acquisition.
