The ASN Lookup API is a powerful tool for developers who need to retrieve information about a specific Autonomous System Number (ASN). An ASN is a unique number assigned to a network by a regional Internet registry, such as ARIN, RIPE, or APNIC. The ASN Lookup API allows developers to query this information using an IP address or ASN number and returns data such as the associated organization and Internet Service Provider (ISP).
This API can be used for a variety of purposes, such as identifying the network origin of IP addresses. This can be useful in troubleshooting connectivity issues, determining the location of a network, and identifying potential security threats. Additionally, the API can be used to gather information about the size and scope of a network, as well as identify any upstream or downstream connections.
The data returned by the ASN Lookup API is provided in JSON format, making it easy to integrate into a wide variety of applications and systems. The API also supports batch processing, allowing developers to query multiple IP addresses or ASN numbers in a single request. With its powerful capabilities and easy-to-use interface, the ASN Lookup API is an essential tool for any developer working with IP addresses and networks.
Pass the ASN number to the API and receive information like:
Network troubleshooting: The ASN Lookup API can be used to identify the network origin of IP addresses and troubleshoot connectivity issues by providing information about the ASN and associated organization.
Geolocation: The API can be used to determine the location of a network by providing information about the associated organization.
Security threat detection: By identifying the network origin of an IP address, the API can help in detecting potential security threats and protect against them.
Network mapping: The API can provide information about the size and scope of a network, as well as identify any upstream or downstream connections, which can be useful for network mapping and analysis.
IP address validation: The API can be used to validate an IP address by checking if it is associated with a valid ASN.
Compliance: The API can be used to check if an IP address or a network is compliant with certain regulations or standards by providing information about the associated organization and ASN.
Besides API call limitations per month, there are no other limitations.
Retrieve information based on AS number.

Prices are based on a recurring monthly subscription depending on the plan selected — plus overage fees applied when a developer exceeds a plan’s quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.
