ASN Lookup
Quickly lookup updated information about specific Autonomous System Number (ASN), Organization, CIDR, or registered IP addresses (IPv4 and IPv6).
An ASN (Autonomous System Number) Lookup tool is a service that allows you to find information about an Autonomous System (AS), which is a collection of networks that operate under a single administrative domain. An AS is identified by a unique ASN, which is assigned by the Internet Assigned Numbers Authority (IANA). The ASN Lookup tool allows you to find information about an AS, including its name, country, and internet service provider (ISP).
How to Use an ASN Lookup Tool?
Enter the ASN number.
You can find the ASN number by using other networking tools, such as traceroute, or by searching for the organization name or ISP associated with the AS.
Run the Lookup tool: Click the "Check" button to run the ASN Lookup tool. The tool will scan its database and provide information about the AS associated with the ASN number.
Review the results: The ASN Lookup tool will provide a report that lists the name of the AS, the country where it is located, and the ISP that manages the AS. It may also provide additional information, such as the IP address ranges associated with the AS.
Use the information: Once you've looked up the ASN, you can use the information for a variety of purposes, such as troubleshooting network issues, identifying potential security threats, or optimizing network performance.
