Frequently Asked Questions
What is an ASN?
An Autonomous System Number (ASN) is a unique identifier assigned to networks on the internet. Major companies like Cloudflare (AS13335), Google (AS15169), and Amazon (AS16509) each have their own ASNs.
What is BGP?
Border Gateway Protocol (BGP) is how networks on the internet share routing information. BGP state shows how traffic is routed through different autonomous systems.
What data source is used?
This tool uses RIPE Stat, a public API provided by RIPE NCC that aggregates internet routing and registration data.
Common use cases
Teams and individuals use this asn / ip network lookup for debugging, validation, data cleanup, testing, and repeatable browser-based workflows.
