Questions

What is an ASN lookup?

An autonomous system number identifies a network on the public internet, such as an ISP or a cloud. It is not a street address and not a person.

How do I look up an ASN?

Open /asn/ and the number, for example /asn/13335 for Cloudflare or /asn/55836 for Jio. /asn/AS13335 redirects to /asn/13335. In the search box, include the AS prefix.
