find an IP address
Computer networks and the Internet do not identify devices (whatever their size, even smartphones) by the name you give them. Computers have better middle numbers, and the numbers they use to identify them are called IP addresses. When it comes to your computer, there are a number of IP addresses that are responsible for communicating with the outside world (the Internet). In some cases you will need to find these IP addresses. But how can they be accessed?

IP is the title of the Internet protocol, which is itself part of the Transmission Control Protocol / Internet Protocol (TPC / IP), abbreviated to IP. TCP / IP is the language used by most networks to communicate.

When it comes to your computer, there are a number of IP addresses that are responsible for communicating with the outside world (the Internet). One of the most important IP addresses for connecting to the Internet is your IP router. This IP address is usually assigned to the router by your Internet Service Provider (ISP), and the router manages all of your computer traffic to the Internet in this way.

Computers connected to the Internet, whether in the form of Wi-Fi or Ethernet, at home or at work, use their own IP addresses, which are usually assigned to them by the router. In this way, all the nodes on the Internet (all devices and equipment connected together in a network are called nodes) can also communicate with each other. The protocol used by the router to assign IP addresses is called Dynamic Host Control Protocol (DHCP).

The dedicated IP addresses you receive are dynamic because they are usually temporary, and the router usually assigns a different address to it after re-requesting a node to receive an IP address. But you can change the router settings so that nodes are assigned static or static IP addresses so that they never change. This is especially important in some network connections, especially when you need to find the same node over and over again.

IP addresses are usually created in the same format of 32-bit numbers in the form of 4 sets of decimal numbers ranging from 0 to 255 and separated by a dot. This type of IP addressing system is called version 4 or IPv4. In this way you can theoretically have the address from to This is limited to 4 billion addresses, which is not enough for our world today. For this reason, the IPv6 addressing system was introduced, which is 128-bit and uses 16 classes of hexadecimal digits instead of 4, which can be used to create 340,282,366,920,938,463,463,374,607,431,768,211,455 new addresses. A figure that will not end soon.

This was all useful information that we were familiar with. But how can we find our IP address?

Identify public IP address / Internet

There may come a time when you need to know the address of your IP router assigned to you by your ISP. This address is used in special cases such as VoIP calls or remote access software.

In addition to your address, you will get a lot of other information, including the name of your Internet service provider and your public location (called GeoIP). This is because your ISP has a range of IP addresses for use that are unique to the ISP and are identified by it.

The easiest way to find your public IP address is to type what is my IP in Google.

But Google only shows you the IP address. There are several different sites that do the same thing but provide you with more information. These sites find your address because you visited the site, your router sends a request to visit that contains its IP address. Sites like ,  Iplocation and addition to the address, your ISP, your city (if you do not know where you are) and sometimes it displays a map of the day. But this GeoIP information is not very accurate. Generally, you will get your approximate location (where the server is located), not the exact location of your computer. Obtaining the true and accurate address of a public IP address usually requires obtaining permission from an Internet service provider.

Find your internal IP address

Each device that connects to your internal network (whether at home or in the office) has its own IP address. It does not matter if you are using Wi-Fi or Ethernet. Your computer, smartphone, smart TV, your network printer, or any other device that connects to this network all need an IP address to communicate with each other or connect to the Internet.

In the most common form of a network, your router has an IP address similar to called a gateway. Usually when you look for the IP address of other devices, you come across it a lot. This means that your router uses DHCP to assign addresses to devices. Here only the last set of numbers changes, such as or, etc., and this depends on the range defined in your router.

If you are using a large internal network, another type of these numbers called a subnet will help you to divide the network into different groups. The subnet mask used by most home networks is

How do you find these addresses? It is easy to do in Windows but requires a command line. Type cmd in the search bar of the Start menu to find the command line application. In the command line window, type ipconfig.

The information obtained from this command is more than just an IP address. You will also get a subnet mask and a Default Gateway. In the middle part of the extracted information, the type of connection is also specified (Ethernet Ethernet adapter). If you are using Wi-Fi, this information is displayed as a Wireless LAN adapter Wi-Fi.

Go to System Preferences on your Mac to get this information. Select Network on this page. On the left, select the connection type to find the corresponding IPs. You must click on the TCP / IP tab to view the information. You can also get this data like Windows by terminal and typing ipconfig command.

If you want to get the IP address of other devices connected to the network, you need to go to the router settings page. How to access this page depends on the router model and the software it uses. You can usually access it by typing the IP address of the router in the web browser address bar connected to the same network.
