What is an IP address? Why is it use the internet

Where everything is connected through the online world, "IP Address" has become a frequently heard term, but not everyone understands what it is or how important it truly is for using the internet. However, I can tell you that an IP Address affects security, website access, and even marketing strategies. 💡🌐

What is an IP address? 🏠

The meaning and function of IP

The term "IP Address" stands for Internet Protocol Address, or "the identification number of a device on the internet." It's like a "house number" used to indicate the location of a computer, mobile phone, or server on the internet network.

Every time you visit a website, send an email, or watch an online video, data is transmitted from one IP address to another so the system knows "where the data needs to go" and "who the recipient is."

How do IPv4 and IPv6 differ?

In the past, we used IPv4, which has a numerical format like 192.168.1.1. However, as the number of connected devices increased beyond the limit, IPv6 was developed, which supports more devices and offers increased security, such as 2001:0db8:85a3::8a2e:0370:7334. Although the average user may not notice much difference, IPv6 is a more stable and secure connection than IPv4.

Types of IP Addresses🗺️

Public IP vs Private IP

• Public IP is an IP address used to connect to the internet, such as the IP address of a home or office, which can be identified from outside.
• Private IP is an internal network IP, such as the Wi-Fi we use at home, which is not visible from outside the network.

Static IP vs Dynamic IP

• Static IP is a fixed, unchanging IP address suitable for servers or businesses requiring stability.
• Dynamic IP is an IP address that changes every time you connect to the internet. It's suitable for general users because it's more convenient and secure.

Why is an IP address important for the internet? 🌍

Identifying location and communication routes

As mentioned above, an IP address is like a "house number" that indicates where your device is located on the internet network. Every time you open a website or send data, the system uses the IP to correctly identify the origin and destination of the information. Without an IP address, the internet would not be able to connect different devices at all.

Packet data exchange and routing

When you visit a website or watch a video, the information is broken down into small pieces called "packets" and sent along a route, using the sender's and receiver's IP addresses to determine the path.
This process happens quickly, in fractions of a second, allowing you to watch videos, listen to music, or shop online without interruption.

Security and Access Control

IP addresses are also used by websites to "restrict access" or "track user behavior."
For example, some countries cannot watch certain Netflix or YouTube content because the system detects your location based on your IP address.

Therefore, if you want to hide your IP address to protect your privacy or access blocked content, using a VPN is the safest and most convenient way, especially BullVPN, which allows you to change your IP to another country with just one click.
