How to identify an IP address

An IP address (Internet Protocol) is a unique address that electronic devices use to identify and communicate with each other on a computer network. This address is determined using the IP (Internet Protocol) standard. Simply defined, the IP address is the computer address used on the Internet. Therefore, the IP address is unique to each device.

In addition to computers, other devices that may have unique IP addresses include routers, switches, infrastructure servers, printers, Internet fax machines, and even some phones.

IP addresses are assigned and managed by the IANA (Internet Assigned Numbers Authority). IANA assigns IP address blocks to any of the four Internet registration areas (ARIN, RIPE NCC, APNIC and LACNIC), which then assign smaller IP address blocks to Internet service providers. and business.

A normal IP address consists of 32 bits or 4 bytes of address normally displayed by 4 digits (each number is limited from 0 to 255) and separated by dots. We have an example of the IP address as follows: '192.135.67.201' . The range of numbers between 0 and 255 is usually displayed by 8 bits, also known as an 'Octet'.

However, the limitation of this IP address version is that the number of IP addresses is limited to 4, 294, 967, 296. So a method of assigning a new IP address named CIDR has replaced the method France above. The CIRD method is also applied to the next version (IPv6) of the IP address.

The new version of the IP address is 128 bits or 16 bytes in width, this version will allow a large number of IP addresses to become available to computers on the Internet.

Classify IP addresses

There are two types of IP addresses: static IP and dynamic IP. When the IP address of the computer is the same every time the computer connects to the network, it is called a static IP address. However, when the computer's IP address changes each time the computer is connected to the network, it is a dynamic IP address.

What is your computer's IP address?

Until now you must be wondering "What is my IP address?" and "How do I identify my IP address".
It is not difficult for you to identify an IP address. However, the methods will vary across different situations. Here are some simple methods to determine your computer's IP address when you are connected to the Internet, when you use a Macintosh computer when using a Windows computer, and even how to identify an IP address. of email sender.

When connecting to the Internet

There are many websites on the Internet that can detect IP addresses when computers are connected via the Internet. However, if you are on a LAN or a home network, those sites may detect the IP address of the network router.

When using a Macintosh computer

On a Mac, the IP address is found at the TCP / IP control panel, when the computer is Mac OS X, the IP address is found in System Preferences under 'Internet and Network'.

When using a Windows computer

If you want to detect the computer's IP address (in case you're using Windows), the search process is very simple:

1. Click ' Start ' on the Windows taskbar.
2. Select ' Run '.
3. Enter ' cmd ' in the text input box. This command will go to the command prompt menu.
4. At this menu, enter ' ipconfig / all '.

You will find the computer's IP address at the IP address field.

Detect the IP address of the email received

If you want to detect the IP address of the computer that sent you the message, you can find it at the beginning of the email header. Normally, this information will be hidden. If you click 'Show Headers' while reading email messages on the Internet, the computer's IP address from the mailing place will be displayed.

Some values ​​of IP addresses

IP addresses are useful for detecting and resolving intrusion problems and Internet threats. These IP addresses also help reduce spam or when you receive messages with threats or dangerous viruses that can be accessed via email.
