NETWORK INTELLIGENCE

ASN & BGP Lookup

Analyze the Autonomous Systems (AS) that form the backbone of the internet. Find out who owns an AS number and managed IP prefixes.

What is an Autonomous System (AS)?

The internet is a network of networks. Each of these large networks is called an **Autonomous System (AS)** and has a unique identification number (**ASN**). For example, Google is AS15169, and Cloudflare is AS13335.

Why is BGP Important?

BGP (Border Gateway Protocol) is the protocol that allows different ASs to talk to each other. Think of BGP as the "GPS" of the internet; it decides the fastest route for data to travel. With this tool, you can see which IP blocks a company announces to the world.

Types of ASN

There are mainly three types: **Stub AS** (Connected to one ISP), **Multihomed AS** (Connected to multiple ISPs), and **Transit AS** (Allows traffic to pass through, e.g., Tier-1 Carriers).

ASN FAQ

Can I find ASN from IP?
Yes, simply enter any IP address (e.g., 1.1.1.1) into this tool, and we will automatically detect which ASN it belongs to.
Bu veriler ne kadar güncel?
Veriler RIPE NCC (Avrupa IP Ağları Koordinasyon Merkezi) veritabanından anlık olarak (Real-time) çekilmektedir. BGP anonsları 5-15 dakika içinde sisteme yansır.
