IP stands for Internet Protocol. The IP address is an identifier for a device on the internet or local network. It allows for the transfer of information between devices on the network.
The address is a string of numbers, separated by colons or dots (depending on the protocol version). It consists of two parts: the network number and the host number. The first is used to recognize the network on which the device is located, while the second one is used to identify a specific device on this network.
For example 220.127.116.11. or 1001:0DB1:AA10:0001:0010:0010:0010:00FB. These are two IP addresses that use different IP versions.
All IP addresses are assigned by the Internet Assigned Numbers Authority (IANA) and then reassigned by providers to their customers.
IPv6 and IPv4 are different versions of the Internet Protocol.
The fourth version of IP has been in operation since 1982 and is still the main protocol used on the internet today. There are more than four billion addresses in the IPv4 address pool, but due to the development of the internet and the growth of traffic, this number is not enough.
The length of the IPv4 address space is 32 bits. The address consists of 4 parts separated by dots. The full range of IP addressing ranges from 0.0.0.0 to 255.255.255.255.
For example: 000.001.002.003
This is a new protocol that replaces the fourth version. It solves the problem of lack of IP addresses as it can provide an almost infinite number of device addresses.
The main difference between IPv6 and IPv4 is the length of the address space — 128 bits instead of 32.
IPv6 consists of eight groups, separated by colons. Unlike IPv4, this version uses not only numeric but also alphabetic addressing methods
For example: 1001: 2db2: 33a3: 0000: 0000: 4a4e: 5555: 6666.
The IP address can reveal some information about your device: computer name, name, and version of the internet browser, User-Agent, screen resolution, provider, and location.
Geolocation is limited to country, area, and city. The exact home address will not be revealed. It can only be revealed by your internet service provider and only in exceptional cases, for example, upon request from law enforcement agencies./p>
Devices use IP addresses to discover each other and exchange information on the internet.
This is how it works:
- First, the device connects to the internet service provider's network, that is, to its local network.
- Then the provider gives the device access to the internet via the router.
This means that your internet traffic goes through the provider's servers.
Everything you do on the internet — from watching a movie to chatting in a messenger — is an exchange of data between servers and devices. Imagine you want to go to a particular page on a website. In order to do this, your computer must contact the server at its address. The server, in turn, will send the page back to the address of the device. This data transfer occurs using the addresses of “sender” and “recipient”. Therefore, everyone must have a unique IP address to be identified on the network.
Dynamic IP address changes every time your device connects to the internet. Devices are assigned with a temporary IP address, selected by internet providers from the pool of available free IP addresses. Dynamic IPs cannot be accurately tracked.
A dynamic IP is considered more secure because it is rather hard for hackers to track its changes and exploit it. Also, the provider does not need to restore the client's IP address if, for example, they move to a new physical address/location.
A static address is assigned to a particular user and does not change, unlike a dynamic IP.
Regular users do not need static IPs. But some companies use it when they host their own servers. A static IP ensures that linked websites and emails will have unchanging IP addresses and it would be possible to track them.
Everyone who connects to the internet has two IP addresses: private and public. The first one is used within the local network while the second is used outside of it — on the internet.
A computer, a phone, a tablet is assigned a unique address within the local network. The router needs to identify every device, so it generates private addresses for each one.
With private IP addresses, devices can communicate with each other within the local network, but they cannot access the internet. This requires a public IP address.
Public (or external) IP is used to connect to the internet. This is the address that sites and users can see and identify.
Each public IP address is unique and cannot be duplicated. Typically, internet service providers have a large pool of public IP addresses that they assign to their customers, more specifically, to their routers.
The router allows home network devices to use one public IP address to access the global network. This means that your laptop and phone that are connected to the same Wi-Fi router will have the same public IP, but different private addresses.
The IP address is used for many purposes. Let's take a look at some of them:
- To get your location data. Sometimes websites apply geo-blocking — they limit access to specific pages or content on the website if it is not relevant in a particular country. This approach works both ways since some websites use location to show relevant content. For example, if you live in France, Netflix will suggest popular local TV shows and movies. Search engines work in about the same way — results that are most relevant to a specific location have higher search positions.
- Serving personalized ads. Advertisers use IPs to track user actions and offer the most relevant advertisements. For example, if you have searched for tours to Europe, you will see relevant advertising with suggestions from travel agencies.
- Tracking copyright infringers. Some European and American agencies monitor torrents to trace IPs and identify violators.
- Theft. This is rather an exception, but some hackers may steal your IP and sell your stolen data on the darknet.
There are several ways of doing this.
- Use special online tools. Our tool allows you to quickly get all the necessary information: IP address, geolocation, User-Agent, and much more.
- Ask your provider. Contact technical support or check the “Personal account” section.
- Manually. If you are using Windows, go to Command Prompt and type ipconfig to launch a special console application. On macOS, just open System Preferences.
The public IP address is used to identify your device on the internet. It is assigned by your internet service provider, is unique and cannot be repeated.
You can use our tool to find out what your public IP address is.
The IP address can help identify the approximate location of your device. Services use special databases to determine the location: country, area, and city.

The IP address is assigned to every device: computer, phone, hosting server, router, printer. This is how it works:
- The global authority — Internet Assigned Numbers Authority — distributes a pool of addresses among internet service providers.
- The providers register networks on their routers.
- When a user contacts a provider, the provider assigns them an IP address through which they connect to the internet.
Search engines frequently use IP addresses to display relevant search results for your location and language.
Websites use IPs to display region-specific content or prevent you from accessing pages or content that are not intended for your region.
Advertisers use IP data to track users and show them the most relevant ads.
You can change the private IP that is used in your local network to connect to the router. You can do it by changing the router settings through the Windows Control Panel or MacOS Network Panel.
If you need to change the public IP address that is used to access the internet, contact your internet service provider.
Use a proxy server or VPN. That way, you can hide your IP address when you go online.
Here's how it works: your internet traffic goes through a separate server that processes and forwards it to the network. Websites will see only the IP address of the intermediate server, not your computer.
Log into your VPN provider's account, select the VPN server and connect to it. Then go to the IP checker tool. It will show your new VPN address, location, and other information.
IPv4 is the fourth version of the Internet Protocol and its length is 32 bits. Your IP address consists of 4 parts, separated by a period and it looks like this: 100.101.102.103.
To find detailed information about your IPv4, just enter it into the special field at the top of this page.
IPv6 is the sixth version of the internet protocol and this 128-bit protocol can provide an almost infinite number of addresses. It consists of eight groups, separated by colons. For example, 1002:0db3:45a6:0000:0000:7a8e:9460:5334.
It is almost impossible to determine the exact home address by IP. All specialized tools can show your location only at the city level. Websites can see the address of your internet provider’s DNS server as your IP address.
The only way to get personal data is to request it directly from your provider. But this is possible only in extraordinary cases, for example, by law enforcement agencies.
IP addresses can show only approximate location, data about the provider, your web browser, and other technical characteristics. It is almost impossible to learn the exact home address or your personal information.
Just use our tool. Enter the site domain and click on the “Check IP” button. In a few seconds, you will receive detailed information about the IP address.
