What an IP Address Lookup Shows

An IP address lookup turns a raw IP into the public information registered against it. Every IP is leased to a network operator and announced from a known region, so a lookup can reveal:

  • Geolocation: country, region and (sometimes) city, plus rough coordinates.
  • ISP / organization: the provider or company that owns the address.
  • ASN: the autonomous system number and network block it belongs to.
  • Reverse DNS: the hostname (PTR record) mapped back to the IP, if any.

What it cannot show is a person's name, their exact home address, or what they do online. An IP is a network identifier, not an identity. Read more on what an IP can and can't reveal →

How Accurate Is IP Geolocation?

Geolocation is an estimate, not a GPS fix: reliable at the country level, hit-or-miss at the city level, and never precise to a street address. Mobile and VPN/proxy addresses are the least accurate.

Frequently Asked Questions

What is an IP address lookup?
An IP lookup takes any public IP address and returns what is publicly known about it: its approximate geolocation (country, region, city), the ISP or hosting provider that owns it, its ASN (autonomous system number), and its reverse-DNS hostname.
Can I look up any IP address?
You can look up any public IPv4 or IPv6 address. Private addresses (like 192.168.x.x) and reserved ranges are not registered to a public owner, so they return little or no geolocation data.
How accurate is the location from an IP lookup?
It is an estimate, usually accurate to the country and sometimes the city or region, but it can be off by many miles. IP geolocation never reveals a street address; it points to the area served by the ISP, not a specific home.
Does an IP lookup reveal who someone is?
No. A lookup shows the network and approximate area an IP belongs to, not a person's name or identity. Only the ISP can link an IP to a customer, and only with a legal request.
Is it legal to look up an IP address?
Yes. The information an IP lookup returns (geolocation, ISP, ASN, reverse DNS) is public registry and network data. Looking it up is a normal, everyday networking task.
Do you store the IP addresses I look up?
No. Geolocation runs locally against an offline MaxMind database, so the address you enter is never sent to a third-party service, and we do not log or store your lookups.
