Frequently Asked Questions

What is my IP address?

An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network. It serves two main purposes: identifying the host or network interface, and providing the location of the device in the network. Your public IP address is visible to websites you visit and is used to route internet traffic to and from your device.

Is my IP address public?

Yes — the IP address shown on this page is your public IP address, assigned by your Internet Service Provider (ISP). This is the address that websites, apps, and online services see when you connect to the internet. Your local network also has private IP addresses (like 192.168.x.x) assigned to individual devices by your router, but those are not visible outside your network.

Can my IP address be traced?

Your public IP address can reveal approximate geolocation data — typically your city, region, and country, along with your ISP name. However, it does not reveal your exact street address or personal identity. Only your ISP can link an IP address to a specific customer account, and they typically require a legal request (such as a court order or subpoena) to share that information.

How can I hide my IP address?

The most common ways to hide or change your public IP address include using a VPN (Virtual Private Network), which routes your traffic through an encrypted tunnel to a server in another location; using a proxy server, which forwards your requests on your behalf; or using the Tor network, which bounces your traffic through multiple relay nodes for enhanced anonymity. A VPN is the most user-friendly option for most people.

What is the difference between IPv4 and IPv6?

IPv4 uses a 32-bit address format (e.g., 192.168.1.1) and supports about 4.3 billion unique addresses. Due to the exhaustion of IPv4 addresses, IPv6 was introduced with a 128-bit format (e.g., 2001:0db8:85a3::8a2e:0370:7334) supporting a virtually unlimited number of addresses. Both versions are in active use today, and most modern networks support both.

Does my IP address change?

It depends on your internet connection type. Most home connections use dynamic IP addresses, which can change periodically (when your router reconnects) or when your ISP reassigns them. Business connections and some premium home plans may have static IP addresses that remain constant. Mobile devices typically receive a new IP address each time they reconnect to a cellular network.

Princip IP adres a geolokace

IP adresa (adresa Internetoveho protokolu) je jedinecny identifikator pridelenny kazdemu zarizeni v siti. Plni dve funkce: identifikuje hosta nebo sitove rozhrani a poskytuje adresu polohy pro smerovani dat. Adresy IPv4 jsou 32bitova cisla typicky zobrazena jako ctyri desetinna cisla oddelena teckami (napr. 192.168.1.1), podporujici priblizne 4,3 miliardy jedinecnych adres. Adresy IPv6 pouzivaji 128bitovy format, podporujici prakticky neomezeny pocet zarizeni.

Geolokace IP funguje tak, ze prirazuje IP adresy k fyzickym poloham pomoci databazi udrzovanych spolecnostmi jako MaxMind, IP2Location a regionalnimi internetovými registry. Tyto databaze agreguji data od ISP, regionalnich registru a dalsich zdroju pro odhad zeme, regionu a mesta spojeneho s kazdym rozsahem IP. Presnost geolokace se lisi — detekce na urovni zeme je typicky 95%+ presna, ale presnost na urovni mesta muze byt mnohem nizsi, zvlaste ve venkovskych oblastech nebo pri pouziti VPN a proxy.

Vase verejna IP adresa je pridelena vasim poskytovatelem internetovych sluzeb (ISP) a je viditelna pro kazdy web, ktery navstivite. Muze odhalit vasi pribliznou geografickou polohu a nazev ISP, ale ne vasi presnou adresu ulice ani osobní identitu. Privatni IP adresy (jako 192.168.x.x nebo 10.x.x.x) se pouzivaji v ramci lokalnich siti a nejsou viditelne pro externi internet. Pochopeni vasi IP adresy je uzitecne pro reseni problemu se siti, konfiguraci vzdaleneho pristupu, nastaveni herniho serveru a overeni, zda pripojeni VPN funguje spravne.

Casto kladene dotazy

Jak je presna geolokace IP?
Presnost na urovni zeme je typicky nad 95 %. Presnost na urovni regionu a statu je kolem 80-90 %. Presnost na urovni mesta se velmi lisi, od 50-80 %, v zavislosti na ISP a regionu. Geolokace nedokaze presne určit presnou adresu ulice — odhaduje na zaklade polohy infrastruktury ISP.
Mohu zmenit svou IP adresu?
Ano. Nejjasnejsi zpusob je restartovat router, ktery muze ziskat novou dynamickou IP od vaseho ISP. Pouziti VPN nebo proxy zobrazi webum jinou IP adresu. Nekteri ISP nabizeji staticke IP za dodatecny poplatek, zatimco mobilni pripojeni typicky meni IP pri kazdem znovupripojeni.
Jaky je rozdil mezi IPv4 a IPv6?
IPv4 pouziva 32bitove adresy (napr. 192.168.1.1) a podporuje priblizne 4,3 miliardy jedinecnych adres. IPv6 pouziva 128bitove adresy a podporuje prakticky neomezeny pocet. IPv6 byl zaveden, protoze adresy IPv4 dochazely. Vetsina modernich siti podporuje obe, ale adopce IPv6 stale roste.
