Public IP Address: Everything You Need to Know

Many of you should be aware of IP addresses. Every time we go online, we use an IP address. But do you know what a public IP address is? And why should you care about it? We will explain everything you need to know about public IP addresses in a fun and easy way!

What Is a Public IP Address?

You can think of the Internet as a giant book of addresses, where each device needs a unique address to communicate with each other. And that unique address is called a public IP address.

A public IP address allows other devices on the Internet to find and communicate with your device. Without it, sending messages, loading web pages, and streaming movies would be like trying to send a letter without an address.

Sometimes, a public IP is permanently assigned to your device or domain name. For example, https://xvpn.io/ has a dedicated public IP address that is shared so people around the world can find it.

Other times, a public IP address is temporarily assigned to your computer or mobile device from a pool of public IPs managed by your ISP.

Public IP Address Ranges

What would it be like to try to organize a world map if each house didn’t have a unique identifier – chaos, right? That’s why public IP addresses are unique worldwide. They usually look like 4 numbers separated by periods, such as 192.0.2.125. Public IP addresses fall within specific ranges set by the Internet Assigned Numbers Authority (IANA). These ranges include:

• IPv4: 1.0.0.0 to 223.255.255.255 (most public IPv4 addresses)
• IPv6: 2000::/3 (a larger range to accommodate the growing number of internet devices)

These ranges ensure that every device on the internet has a unique address, preventing address conflicts and confusion.

Public IP addresses are those that don’t fall within the private IP address ranges. So, what are private IP addresses? And what’s the difference between public and private IP addresses? Keep reading to find out.

Public vs Private IP Addresses: What’s the Difference?

Things are getting interesting. While a public IP address is like your home address visible to the world, a private IP address is like the room number inside your house. Devices on your local network, such as your phone, PC, or smart TV, use private IP addresses to communicate with each other. Your router cleverly translates these private addresses to your public IP when communicating with the internet.

Here are the key differences between public and private IP addresses:

Feature	Public IP Address	Private IP Address
Example	203.0.113.1, 8.8.8.8	192.168.1.1, 10.0.0.1
Access Scope	External communication on the internet	Internal communication
Use Case	Devices needing internet communication, like servers, websites, email servers	Devices within a home or office network, like home networks, internal company servers, printers, routers
Assigned By	Your ISP	Router or network admin
Unique or Not	Globally unique. Ensures one device is identified on the internet	Unique within the LAN. Can be reused in different networks
Number of addresses	Limited. IPv4 addresses are running out, IPv6 provides a larger range	Relatively unlimited. Same private address can be reused in different local networks
Security	Exposed on the internet. Prone to external attacks, needs additional security measures like a VPN	Relatively safe. Not directly exposed on the internet, but still needs internal network security
NAT needed	No. Can be routed directly	Yes. Needs NAT to translate private IP to public IP for internet access
Cost	Usually requires payment to obtain a public IP address	Free, assigned internally within the local network

In summary, you need at least one public address, usually assigned by your ISP. Private addresses are hidden behind it using Network Address Translation (NAT). So, do you know what your public IP address is?

How to Protect Your Public IP Address?

Protecting your public IP address is important because it is exposed on the internet and vulnerable to various risks and attacks:

• Security Risks: Public IP addresses can be accessed through the internet, making devices susceptible to hacking, exploits, unauthorized access, and other network threats.
• Privacy Leaks: A Public IP address can be tracked and monitored, leading to the exposure of personal information and location. This can be used for identity theft, stalking, or other malicious purposes.
