IP lookup
Look up any IP
See the network, country, and provider behind any address.
Couldn’t reach the registry. Showing network data only.
How it works
Where this comes from
-
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
-
The provider
ASN and ISP are who actually announces this address on the internet. We refresh that list every hour
-
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
-
Checked at
That's when we checked the address. The data is current as of that moment
API
The same JSON the table uses. Anonymous: 30 requests per minute. Partners send the X-Amper-Ipinfo-Key header.
- country — ISO country code of the IP’s network
- city, region, postal — filled only when the operator publishes them; timezone — from the feed, or when the place has a single zone
- asn / isp — origin network (ASN) and organisation
