ASN Lookup API
An Autonomous System (AS) is a group of IP networks run by one or more network operators with a single, clearly defined routing policy.
When exchanging exterior routing information, each AS is identified by a unique number: the Autonomous System Number (ASN). An AS is also sometimes referred to as a routing domain.
Autonomous system numbers can be public or private. Public ASNs are required for systems to exchange information over the Internet. A private ASN can be used instead if a system is communicating solely with a single provider via Border Gateway Protocol (BGP).
In this API method, Greip will help you lookup any given AS Number and returning all data related to it, like:
name
, org
(the organization name), country
, domain
, email
, phone
, totalIPs
, list of all routes (v4 & v6) related the given AS Number, etc.The information returned from this method — like any other method in Greip — is real-time data, you'll always get the up-to-date data no matter what's the type of your subscription.
