About this tool

What Is the IP Address Lookup?

The IP Address Lookup tool returns detailed geolocation and network intelligence for any IPv4 or IPv6 address. Enter an IP to see its country, region, city, ISP, organization, and ASN — plus a classification of whether it is a residential, datacenter, or mobile address. It is the quickest way to identify and vet an IP, free and without registration.

Key Features

Country, region and city-level geolocation
ISP, organization and ASN details
Datacenter vs residential vs mobile classification
Works for both IPv4 and IPv6 addresses
Instant results with no account required
Useful for proxy vetting and fraud checks

What an IP Lookup Tells You

Every public IP address carries metadata about the network it belongs to. An IP lookup queries geolocation and registry databases to reveal the approximate physical location, the internet service provider, and the Autonomous System Number (ASN) that owns the range. It also infers the IP type, which tells you whether an address is a real home connection or a server in a datacenter.

Why IP Type Matters

For proxy users and anti-fraud teams, the residential-vs-datacenter distinction is critical. Datacenter IPs are cheap and fast but easily detected and blocked by major sites, while residential and mobile IPs are trusted because they belong to real consumer connections. Checking the type before you rely on an IP saves you from blocks and bad data.

Common Use Cases

  • Verifying the real location and type of a proxy IP
  • Investigating suspicious traffic or fraud signals
  • Confirming geo-targeting is working as expected
  • Looking up the ISP and ASN behind any address

Frequently Asked Questions

How accurate is IP geolocation?

Country-level accuracy is very high, typically over 99 percent. City-level accuracy is more approximate because IPs are mapped to ISP infrastructure rather than a precise address, so treat the city as a close estimate rather than an exact location.

Can I look up any IP address?

Yes, you can look up any public IPv4 or IPv6 address. Private and reserved ranges (like 192.168.x.x) have no public geolocation because they only exist inside local networks.

What is an ASN?

An ASN (Autonomous System Number) identifies the network operator that owns and routes a block of IP addresses. It is a reliable way to tell which company or ISP an IP belongs to, which helps distinguish datacenter providers from consumer ISPs.

Does this detect VPNs and proxies?

The tool classifies whether an IP is datacenter, residential, or mobile, which is the strongest signal for spotting many VPNs and proxies, since most run on datacenter ranges. It is a useful first check for fraud and vetting.

Is the IP lookup free?

Yes, it is completely free with no sign-up. You can look up as many addresses as you need directly in your browser.
