What this lookup shows

The lookup identifies the IP version and may return the network owner, ISP, autonomous system number, country, region, city, and timezone associated with the address.

ASN data helps identify the network announcing an address on the internet. The listed organization may be an ISP, cloud provider, university, business, VPN operator, or content-delivery network.

Location limitations

IP geolocation is an estimate, not GPS. It cannot reliably locate a person, router, or house. VPN exits, mobile gateways, corporate networks, and ISP infrastructure can produce distant results.

Addresses that cannot be looked up

Private, loopback, documentation, benchmark, multicast, reserved, and CGNAT shared addresses are not normal public destinations. RouterNAT rejects those ranges instead of presenting misleading location data.

Privacy and acceptable use

RouterNAT does not save submitted IP addresses in its application database. A geolocation provider processes public-IP lookups. Use this tool only for lawful network administration, research, or troubleshooting.
