ASN Lookup

Provider information, country, RIR and announced IP ranges

Fetching ASN data...

What is an ASN?

Every ISP, company or organisation that operates an independent network on the internet receives a unique number: the Autonomous System Number (ASN). Networks use these numbers through the BGP protocol to exchange routing information with each other.

Where does the data come from?

Data is fetched from the RIPE Stat API and the official RDAP APIs of the 5 Regional Internet Registries: ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC.
