IP Address Lookup

Geolocation, ISP, reverse DNS and VPN or proxy status for any IPv4 or IPv6 address.

What is an IP Lookup?

An IP lookup is a query that retrieves information associated with a specific IP address. Every device connected to the internet has a public IP address: a unique identifier that reveals details about its network, location, and ISP. With IPPriv's free IP lookup tool, you can instantly access this information for any IPv4 or IPv6 address, with no account required.

What IP Address Information Can You Find?

A single IP lookup can return a wide range of information about an IP address:

  • Geolocation: country, region, city, latitude and longitude
  • Network information: ISP, organization, ASN and timezone
  • DNS records: hostname and PTR records via reverse DNS lookup
  • Privacy signals: VPN, proxy, Tor exit node, or hosting/datacenter detection

Why Use a Free IP Lookup Tool?

IP address information is essential for developers debugging network issues, security analysts investigating suspicious traffic, and businesses verifying user locations. IPPriv provides real-time IP lookup data through a clean interface and a free API: no API key, no account, and 100 requests per hour per IP.

Frequently Asked Questions

How do I look up an IP address?

Enter any IPv4 or IPv6 address in the search field and click Look up. IPPriv will instantly return the geolocation, ISP, DNS hostname, and security status for that IP.

How accurate is IP geolocation?

IP geolocation accuracy varies by level: country-level is typically 95-99% accurate, region/state-level around 55-80%, and city-level around 50-75%. Results depend on how ISPs register their IP blocks.

What is a reverse DNS lookup?

A reverse DNS lookup queries the PTR record of an IP address to find the hostname associated with it. This helps identify the owner or purpose of an IP: for example, a datacenter, ISP, or corporate network.

What does it mean if an IP is flagged as a VPN?

An IP flagged as a VPN belongs to a known VPN provider's infrastructure. This means the real user's location and identity may be masked. IPPriv detects VPN IPs by cross-referencing known VPN IP ranges and hosting providers.

Can I look up my own IP address?

Yes. When you open the IP Lookup tool, IPPriv automatically detects your current public IP address and shows its location, ISP and VPN or proxy status.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (e.g. 192.168.1.1) and supports about 4.3 billion unique addresses. IPv6 uses 128-bit addresses (e.g. 2001:db8::1) and supports virtually unlimited addresses. Both are supported by IPPriv.
