IP lookup

Look up any IP

See the network, country, and provider behind any address.

How it works

Where this comes from

  1. The registry

    We take country and range from the internet registries: RIPE, ARIN or APNIC. The data is current at request time, not a dump from last month. We cache the answer for about an hour - the next lookup will pull a fresh one

  2. The provider

    ASN and ISP are who actually announces this address on the internet. We refresh that list every hour

  3. City and timezone

    We take city, region and postcode only if the network published them itself. Timezone we set when the place has a single zone - if there are several, we leave it empty

  4. Checked at

    That's when we checked the address. The data is current as of that moment
