IP address lookup
Look up geolocation, ASN, ISP and network details for any IPv4 or IPv6 address.
What this data means
This lookup returns the publicly available information tied to an IP address: country, region, city, ISP, and the Autonomous System Number (ASN) that identifies the network at the routing level. This is the same data that websites, ad networks, and fraud systems use to identify where their visitors are coming from.
How accurate is geolocation?
Country-level accuracy is around 95% or better. City-level is roughly 60–80% in urban areas and worse in rural ones. ISPs allocate large address blocks to a region and route traffic through centralized exchange points, which may be in a different city than the actual user. The coordinates shown are a centroid for the estimated area, not a building or street address.
VPN and cloud IPs
If you look up a VPN exit IP or a cloud server IP, geolocation returns the data center location. An AWS IP from us-east-1 will always show Ashburn, Virginia regardless of where the person behind it is sitting. This is how fraud systems detect VPN and proxy usage.
What the ASN tells you
The ASN is a globally unique identifier for a network. When you see something like AS15169 Google LLC, it means the IP belongs to Google's network. For home connections it shows your ISP. For servers it shows the hosting provider. This is useful for identifying who operates a network, finding the right abuse contact, and confirming whether traffic is coming from a residential connection or a data center.
Common reasons to look up an IP
- Identifying who sent unexpected traffic to your server or firewall
- Checking whether an IP is residential or from a data center (relevant for fraud detection)
- Finding the right network to file an abuse report against
- Diagnosing routing issues by confirming which ISP handles a path
