ASN Info Extended API

Introduction

The ASN Info Extended API is an advanced ASN lookup API that provides a list of active networks from which the ASN receives traffic and transits it. Additionally, the API utilises BigDataCloud's proprietary technology to provide the geographic coordinates of the most active region where the ASN is operating, if available.

Our proprietary network datasets are updated every two hours to ensure accurate and up-to-date information on the ASN. With the extended ASN information, in conjunction with BigDataCloud's network APIs, network engineers and security professionals can monitor and understand the AS routing policies, allowing them to troubleshoot and optimise their network infrastructure.

Get Started

This API is part of the Network Engineering API Package and is available in free and paid plans. Please visit the Network Engineering API Package package page for limits and pricing information.
