Frequently asked questions

Yes, it is completely free and requires no sign-up, no account, and no limits for normal use. The page runs directly in your browser and queries public lookup services in real time, so every result you see is detected live at the moment the page loads.

No. The tool is a plain web page that works in any modern browser on desktop, tablet, or mobile. There is no account, no app to install, no extension, and no email address to hand over. Open the page and the results are already on their way.

This page is fully static and runs on the client side. Your device talks directly to the public lookup APIs, and nothing is stored, profiled, or logged by the website itself beyond the standard server logs your own hosting provider keeps. The Privacy Policy lists exactly which outside services your browser contacts and why.

The tool does not provide a backend API for third-party use — it is a browser page that queries public lookup services directly. The frontend logic is open for educational reference, but automated bulk requests through the site are not allowed, because they would push the third-party providers over their fair-use limits. For your own projects, query those public APIs directly instead.

Every lookup site relies on different geolocation and risk databases, which are compiled and updated independently. Small differences in city placement, ISP naming, or VPN flags between sites are normal and do not mean one of them is broken.

The location, ISP, and risk data come from third-party providers that update their databases continuously as address blocks are reassigned. Recently reassigned addresses can take days or weeks to settle, which is why brand-new server ranges are occasionally misplaced.

A public IP address is the unique address your internet provider assigns to your connection so websites and services around the world know where to send the data you request. All devices behind your router usually share the same public IP, while each device also keeps a private address inside your local network.

IPv4 addresses look like 192.168.1.1 and offer about 4.3 billion combinations, which are nearly exhausted. IPv6 addresses look like 2001:0db8:85a3::8a2e:0370:7334 and provide a practically unlimited space. Many networks today run both protocols at the same time, so your connection may have one address of each type.

Because the internet is in a long transition period called dual-stack operation. Your provider hands out an old IPv4 address and a new IPv6 address at the same time, and your device picks the best one for each website it visits. This page checks both routes in parallel, so if one card shows not available, that side of the transition is simply not active on your network yet.

Usually yes. Most home and mobile connections use dynamic addresses that change after a router restart, a provider maintenance window, or whenever the DHCP lease is renewed. Servers, business lines, and paid upgrades often use static addresses that stay the same for years. You can watch this first-hand: run a lookup here, reboot your router, and refresh the page to compare the two results.

An autonomous system number (ASN) is the ID of the network operator that owns the address — an ISP like Comcast or Deutsche Telekom, a mobile carrier, or a hosting company such as AWS. Looking at the ASN makes it obvious whether an address belongs to a residential provider or a datacenter, which is why it appears in the details panel next to the ISP name.

Every website, app, and online service you connect to can see your public IP address, and your internet provider can see every destination you contact. Advertisers use it for rough geographic targeting, streaming platforms use it to apply regional catalogs, and banks use it to flag logins from unexpected countries. The address itself is public by design — what matters is which services you trust with your traffic.

Not exactly. An IP address narrows your position down to a city or neighborhood level at best, and geolocation databases are sometimes wrong even about that. Your exact street address is known only to your internet provider, and it is released to authorities through a legal process rather than to random websites. If that city-level precision still concerns you, a VPN hides your real address behind the provider’s server.

Detection relies on public risk databases that track known VPN servers, Tor exit nodes, and open proxies, combined with the type of network the address belongs to. It is a strong hint rather than a guarantee: brand-new VPN servers may be missed, and some datacenter services can look like VPNs. Treat the result as an indicator, not proof.

Compare readings before and after you connect. With the tunnel active, this page should show the VPN server’s address, its city and country, and a datacenter or hosting network type instead of your home ISP. The security card is the quick tell: if the proxy row flags a known VPN while you thought you were unprotected, something is leaking — and if the location still shows your home country, the tunnel is not covering this page. The how-to guide walks through the full check.

The most practical option for everyday privacy is a VPN, which replaces your visible address with the VPN server’s. Restarting a router often produces a new dynamic address, proxies and the Tor network cover different threat models, and mobile connections change address automatically as you move. Each approach is compared in the guide on the homepage.

IP geolocation is based on databases that map address ranges to regions, so results are usually accurate to the city level but can occasionally point to a nearby town or your ISP headquarters. If you use a VPN, proxy, or corporate network, the location shown belongs to that server, not to you.

First press Refresh. If detection still fails, check your connection and temporarily pause ad-blockers, privacy extensions, or DNS filtering, which commonly block the public lookup services. Missing details are usually temporary: the geolocation step may simply be down for a moment. The troubleshooting section of the how-to guide covers every case in detail.

Email info@tuti.lt with the IP address you looked up, what you expected, what you saw, and roughly when. Wrong geolocation entries are corrected by the data providers rather than by this site, but we will point the record out to the right one where we can. The contact page explains what to include so the whole thing is sorted in one round trip.
