Other tools you may find usefulWhat is an IP address and why is it important?
Each device connected to the Internet – a smartphone, computer, TV or server – needs a unique identifier to be able to communicate with other devices on the network. This identifier is the IP (Internet Protocol) address. It works very similarly to a traditional postal address. When you enter a website address in your browser, your computer sends a request for data to the destination server, providing its own IP address to which the server should send the requested information. Without an IP address, it would be impossible to transmit any data over the network.
Our simple tool allows you to check your public IP address instantly and for free. Additionally, the system automatically detects the protocol type (IPv4 or IPv6), network host and basic information about your browser and operating system. All this happens in a fraction of a second, without the need to install any programs or provide personal data.
Differences between IPv4 and IPv6 - evolution of the Internet
Currently, two addressing standards coexist on the Internet. This is due to the fact that the Internet is developing much faster than its creators expected:
- IPv4 protocol:The older and still the most widespread standard. It consists of 32 bits, which is usually written as four groups of numbers from 0 to 255 separated by dots (e.g. 192.168.1.1). IPv4 allows for the creation of approximately 4.3 billion unique addresses. Due to the gigantic number of devices in the world, this pool has already been completely exhausted.
- IPv6:A modern successor designed to solve the address shortage problem. It uses 128-bit addressing written in hexadecimal (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334). The number of available IPv6 addresses is 340 undecillions (3.4 x 10 to the power of 38), which in practice means an infinite address pool. IPv6 also offers better security and faster packet routing.
Comparison of IPv4 and IPv6 protocols
Implementing a new protocol is a long-term process. The table below shows a comparison of both technologies:
| Feature | IPv4 standard | IPv6 standard | Practical significance |
|---|---|---|---|
| Address length | 32 bits (decimal) | 128 bits (hexadecimal) | IPv6 offers an almost unlimited number of unique addresses. |
| Example format | 172.16.254.1 |
2001:db8::1 |
The IPv6 record is longer, but allows skipping sequences of zeros. |
| Security | Optional IPSec support. | Built-in, mandatory IPSec support. | IPv6 is natively more resistant to eavesdropping and data spoofing. |
| Autoconfiguration | Requires a DHCP server to assign an address. | Native stateless auto-configuration (SLAAC). | IPv6 devices can generate their own address after being connected to the network. |
| Address pool | ~4.3 billion addresses. | ~340 undecillion addresses. | Completely eliminates the problem of running out of free addresses. |
How to protect your privacy and hide your IP address?
Because your public IP address is visible to any server you connect to, it can be used to track your online activity or approximate your geographic location. If you want to increase your security and privacy, you can use the following methods:
- Virtual Private Network (VPN):The most popular and effective solution. A VPN connection encrypts all internet traffic and sends it through an intermediary server. To websites, you appear to be connecting from the IP address of the VPN server (which may be in a completely different country).
- Proxy servers:They work similarly to VPNs, but they usually only mediate the traffic of a specific application (e.g. browser) and do not encrypt data. They are simpler and often free, but offer a lower level of security.
- Tor Network:A special network based on onion routing. Your traffic is encrypted multiple times and sent through random network nodes around the world. This ensures maximum anonymity, but drastically slows down page loading speeds.
- Beware of DNS leaks:Sometimes, even with VPN enabled, your DNS queries still go to your local ISP, which allows your IP to be identified. Always verify the tightness of your connection using dedicated DNS leak tests.
Frequently Asked Questions (FAQ)
What is the difference between a private and public IP address?
A private IP address (e.g. 192.168.1.X) is used inside your home network for communication between your router, computer and phone. The public IP address is the one under which the router is visible to the entire Internet. Our website shows your public IP address.
Can my exact home address be determined from my IP address?
No. The IP address allows for geolocation precisely to the country, region and usually the city where the headquarters of your Internet Service Provider (ISP) is located. Exact data on which physical premises the IP data was assigned to at a given second is only available to the Internet provider and can only be made available to the police or prosecutor's office.
What is a dynamic IP address?
A dynamic IP address is an address that changes periodically - usually every time the router is restarted or once a day. This is a common practice among home and mobile Internet providers, allowing for more effective management of the pool of free addresses.
Can two devices have the same public IP address?
Yes. All devices connected to your home Wi-Fi (phone, computer, console) share one public IP address assigned to your router by your Internet provider (thanks to NAT technology).
How to check IP in Windows without using a browser?
Open the Start menu, type "cmd" and launch Command Prompt. Then typeipconfigand press Enter. In the "IPv4 Address" line you will find your private IP address in the local network.
