ASN lookup

Enter an Autonomous System Number — AS15169 or just 15169 — to see who runs the network: the org name, country, the registry that issued it, and when it was registered. Pulled live from RDAP.

What an ASN tells you

You found who owns the network. Now find what's wrong with yours.

An ASN names the operator behind an IP — useful, but it won't tell you why your own connection is slow. Acutis Go runs a 60-second check and says whether it's the network or your machine. Free.
