BGP Viewer
Look up any ASN, IP or prefix: summary, upstreams, announced prefixes and their geolocation.
Queries go directly to RIPEstat's public API (RIPE NCC). Nothing passes through our servers.
Enter an ASN, an IP, a prefix or an organisation name.
About this tool
The BGP Viewer looks up any ASN, IP or prefix and shows its summary, upstreams (transit providers), announced prefixes and their geolocation. It uses the public RIPEstat API, the same source network operators rely on.
- Find out which ASN owns an IP and through which operators it is announced.
- Review every IPv4/IPv6 prefix a given autonomous system announces.
- Investigate peering and transit of your provider or your competitors.
Frequently asked questions
What is an ASN?
An Autonomous System Number identifies a network that announces routes on the Internet via BGP. Carriers, hosts and large companies have their own ASN; AP Interactive operates AS215691.
What is looking up BGP useful for?
To understand how traffic reaches a network, who provides transit, whether it has redundant routes and where it is announced from. It is key for connectivity diagnostics and peering decisions.
