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
- Network name / handle — the label the operator registered for this AS (e.g. GOOGLE).
- Organization — the legal entity that holds the AS, parsed from the RDAP contact card.
- Registry (RIR) — which regional registry issued it: ARIN (North America), RIPE (Europe), APNIC (Asia-Pacific), LACNIC (Latin America) or AFRINIC (Africa).
- Dates — when the AS was first registered and last updated in the registry.
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.
