ASN Lookup
Every public IP belongs to an autonomous system — a network with its own routing identity, usually an ISP, cloud provider, or large company. Enter an IP to see its ASN, the organization behind it, and the registered location.
What is an ASN?
An Autonomous System Number identifies a network that manages its own routing on the internet — for example AS15169 is Google. Every public IP is announced by exactly one AS at a time, which is how you can tell the operator behind an address.
Can an ASN lookup identify a person?
No. It identifies the network operator — an ISP, hosting company, or enterprise. For a home user it names their ISP, nothing more personal than that.
