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.

Endpoints

Request

Parameter
Type
Required
Description
asn
string
Yes
Autonomous System Number as numeric or ASN format (e.g. 123 or AS123 or ASN123)
localityLanguage
string
Optional, default value: en
Preferred language for locality names in ISO 639-1 format, such as 'en' for English, 'es' for Spanish etc. If the requested language is not available for a requested location, it will default to English. If no English variant is known, will provide the native, local names
peersCap
integer (int32)
Yes
This parameter caps the max number of 'receivingFrom' and 'transitTo' entries to retrieve. The default value and the hard limit are 50
key
string
Yes
