Advance TierInstantly get ASN ownership insights with our precisely parsed ASN WHOIS database. Empower your cybersecurity, routing policies, and B2B targeting. Validate ownership, uncover network relationships, and strengthen threat intelligence. Lead your market with superior ASN data.
Network operators and ISPs rely on the ASN WHOIS database to understand how Autonomous Systems exchange routing information. This enables them to identify and select upstream providers and downstream organizations, and to define their routing policies efficiently. With this information, they can form strategic partnerships for traffic exchange, optimize traffic flow, and ensure efficient connectivity between different types of networks on the Internet.
Cybersecurity professionals leverage ASN WHOIS data to trace the origin of cyber threats. They can identify the responsible organization behind malicious ASNs by analyzing the registration and ownership information of those ASNs. This allows them to contact those entities, report the threats, and take action to remove them. These steps enhance network security, ensure smooth operations, and help prevent breaches of sensitive data.
ISPs and networking organizations that are planning to expand their network infrastructure need ASN details to observe already established networks and peering between Autonomous Systems. They need to know the availability of internet number resources to acquire new ASNs or IP addresses strategically. Furthermore, they can examine market needs and predict future resource requirements to plan their network efficiently and on time.
Businesses utilize ASN WHOIS data for market analysis and competitive research. They can identify business opportunities, understand market trends, and recognize potential partnerships and gaps in the market. They can build strategic partnerships through the mutual exchange of traffic and avoid costly transit providers. This way, they can provide optimized and cost-efficient services to their customers and strengthen their position in the market.
The database provides contact details for ASN owners, including their abuse contacts. Individuals and organizations can easily use this information to report harmful online activities like spam or phishing attacks coming from specific ASNs. Security teams can prevent online threats by quickly addressing these malicious activities. This efficient approach ensures a secure online environment for users and protects services from any disruptions.
Internet Service Providers (ISPs) use ASN WHOIS databases to track their IP addresses and see how their networks connect with others. This helps ISPs manage their networks effectively, route customer traffic correctly, and follow guidelines set by the Internet Assigned Numbers Authority (IANA). Proper mapping ensures fast and reliable internet service for all customers.
Use our ASN Whois database to identify network operators, monitor AS ownership and routing, and keep your network secure and running smoothly.

Talk to Sales for DetailsAn ASN WHOIS database contains registration data for Autonomous System Numbers (ASNs). It shows the organization to which an ASN is assigned, its contact information, and routing details. It also reveals the ASNs with which a particular Autonomous System exchanges routes, providing essential insights into how networks are connected on the Internet.
The Internet is made up of numerous Autonomous Systems, which themselves consist of interconnected devices such as computers, mobile devices, and laptops that share data. To uniquely identify each Autonomous System, a number is assigned to it, known as an Autonomous System Number.
An ASN WHOIS database typically provides the ASN ownership, the organization's name, country, and contact details (email, phone). It also includes import and export routing policies and IP prefixes announced by the ASN.
Yes, cybersecurity professionals frequently use ASN WHOIS data to identify the organization responsible for malicious IP addresses or ASNs. This enables them to trace cyberattacks, report abuse, and implement network security measures. They utilize this data to control and mitigate threats.
An Autonomous System (AS) is a single entity or group of networking organizations that operates under a defined routing policy and exchanges routing information with other networks using the Border Gateway Protocol (BGP).
Yes, we do provide free ASN lookups through our ASN Lookup tool , but the number of queries is limited. You will need to upgrade your plan to get full access to the data.
ISPs rely on ASN WHOIS data to understand inter-network relationships, optimize routing policies, and plan for network expansion. It helps them identify potential transit partners, manage their IP addresses, and ensure smooth Internet service delivery by effectively exchanging routing information with other networks.
Internet Exchange Points (IXPs) are physical locations where different types of networking organizations, mainly ISPs and content providers, directly exchange routing information and IP prefixes.
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.
It was a pleasure to communicate with managers: they responded fast and supported me on all stages: as technically as with documents and other legal staff. The best customer commitment! Have a personal approach for each client!
