What is an IP address lookup?
An IP lookup matches a public internet address against a geolocation database. The result describes the network associated with that address: its operator, approximate region and any other details available in the database.
It is useful for understanding an address you already have. It does not discover someone’s IP from their name, email or phone number, and it does not connect to or scan their device.
What can you find out from an IP address?
Read the fields as clues about a network. A country or operator can be known even when a city, region or time zone is not.
| Field | What it tells you |
|---|---|
| Country, region and city | An estimated area associated with the address range. With mobile networks or VPNs, this can be the location of a gateway or server. |
| Network / ISP | The organisation associated with the IP range. This may be an internet provider, mobile operator, hosting company or business network. |
| Autonomous system (ASN) | The routing network associated with the address. An ASN identifies a network, not an individual customer or a particular device. |
| Time zone | The time zone returned for the estimated location. It can differ from the time zone configured on the device. |
| Approximate coordinates | Approximate coordinates from a geolocation database. They do not identify a house or the exact position of a device. |
| IPv4 or IPv6 | The address format used for the lookup. Both versions can describe public internet addresses, and their location records can differ. |
What an IP lookup does not reveal
A network record is not a personal profile. Keep these limits in mind when reading the result.
- A home or GPS location:
- The tool does not identify a street, apartment or the live position of a phone. Coordinates are an estimate about the network.
- A person’s identity:
- An IP alone does not confirm a person’s name, email, phone number or which person used a shared connection.
- Device activity or safety:
- A lookup does not expose browsing history, passwords or open ports. It also does not prove that an address is malicious or safe.
When is an IP lookup useful?
Use the result as one part of a technical investigation, alongside the information you already have.
Investigate an unfamiliar login
Compare the network and approximate region of an address in your account’s login history. A different region is a reason to check further, not proof of an intruder.
Understand website traffic
Look up a public source address from your own logs to identify its network operator. Request patterns and timestamps provide the context a location alone cannot.
Check a VPN or proxy exit
Compare the public address, network and country shown before and after connecting. The result describes the exit visible to that web request.
Troubleshoot a location mismatch
See why a service places a connection in another region. Mobile gateways, corporate networks and old database records can all affect the result.
How accurate is IP geolocation?
There is no single accuracy percentage that applies to every IP address. Results depend on the database, the network and how its address ranges are used.
If two lookup services disagree, neither result should be treated as GPS evidence. Read the country, operator and connection type together, and allow for missing or outdated information.
Mobile and shared networks
Many users can reach the internet through the same gateway. Its registered location may be far from the device.
VPNs and proxies
Traffic routed through a VPN or proxy normally exposes that service’s public exit IP. A lookup describes that exit rather than the original connection.
Database updates
Address ranges can be reassigned or used in a new region before a geolocation database catches up.
Public or private IP: which one can you look up?
IPv4 and IPv6 describe address formats. Public and private describe how an address is used. A valid-looking address is not necessarily a public one.
- Public IP addresses
Public addresses are used for internet communication. This tool accepts public IPv4 and IPv6 addresses and looks up their available network records.
Formats: 8.8.8.8 · 2606:4700:4700::1111
- Local and special-use addresses
Addresses such as 192.168.1.1 identify devices inside a private network. Loopback, link-local and other special-use addresses do not have a useful public location record here.
Local examples: 192.168.1.1 · 10.0.0.1 · ::1
What changes when you use a VPN?
When a web connection goes through a VPN server, the website sees the server’s public exit address. An IP lookup will generally show the network and approximate location associated with that exit.
A changed public IP is one useful check. It does not by itself prove that all traffic uses the VPN or that there are no DNS or WebRTC leaks. Separate checks can help you examine those connections.
IP lookup: questions and answers
Practical answers about geolocation, public addresses and the information shown by this tool.
The lookup is free and does not require a Kryon account. On opening the page, it detects your current public IP. To check another address, replace it in the field and select Check IP.
