An IP address (Internet Protocol address) is a unique numerical identifier assigned to every device connected to the Internet or a local network. This address enables devices to locate and communicate with each other. Think of it as a “digital home address” for your computer, smartphone, or any other internet-connected device.

Why Do We Need IP Addresses?

1. Device Identification
IP addresses ensure the Internet knows where to send data. When you visit a website, your device sends a request to a server, and the IP address helps the server deliver the correct response.

2. Device Communication
They allow devices—such as computers, smartphones, printers, and servers—to interact within a network.

Types of IP Addresses

There are two main versions of IP addresses:

IPv4 (Internet Protocol version 4)

• Format: Four numbers separated by dots (e.g., 192.168.1.1).
• Each number ranges from 0 to 255, providing around 4 billion possible addresses.
• Currently, the most widely used are IPv4 addresses, which are becoming scarce due to the increasing internet-connected devices.

IPv6 (Internet Protocol version 6)

• Format: Eight groups of four hexadecimal digits, separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
• Designed to overcome IPv4 limitations, offering ~340 undecillion unique addresses.
• Ensures future scalability for emerging technologies.

IP addresses can also be classified by their assignment method:

• Static IP Addresses – Permanently assigned to a device, commonly used for servers and critical services.
• Dynamic IP Addresses – Temporarily assigned (usually by a DHCP server) and may change upon reconnection. They are often used in home networks.

Why Should You Know Your IP Address?

Understanding your IP address can be crucial for various scenarios:

1. Troubleshooting Network Issues

• Diagnosing connectivity problems (e.g., if a website isn’t loading).
• Running ping tests or traceroute to identify network failures.

2. Configuring Network Devices

• Accessing your router’s admin panel (requires the router’s IP).
• Setting up port forwarding for gaming, remote access, or hosting services.

3. Protecting Privacy & Security

• Detecting unauthorized access to your network.
• Using VPNs or proxy services to mask your real IP for anonymity.

4. Remote Access & Online Activities

• Connecting to work servers, home security systems, or smart devices.
• Joining restricted webinars or streaming services that require IP verification.

How to Find Your IP Address

On Windows

• Command Prompt: Press Win + R, type cmd, and enter ipconfig. Look for the IPv4 Address Under your active connection.
  
  

Network Settings: 

• Go to Settings > Network & Internet > Status >
• View hardware and connection properties.
  

Task Manager: 

• Open Task Manager > Performance tab > Wi-Fi/Ethernet section.
  

On Android

• Open Settings > Wi-Fi, tap your connected network, and find the IP address listed.
  

On iOS (iPhone/iPad)

• Go to Settings > Wi-Fi, tap the “i” icon next to your network, and check the IPv4 Address field.

Finding Your External (Public) IP

• Visit an IP-checking service —this shows the address visible to the internet.

Can You Find Someone Else’s IP Address?

Yes, but with limitations:

• External IP: May appear in email headers or server logs if you interact online (unless they use a VPN/proxy).
• Internal IP: Only detectable within the same local network (e.g., via ipconfig or router settings).

Note: Tracking others’ IPs without consent may violate privacy laws.

How to Hide Your IP Address

1. Proxy Services (Belurk)

• Masks your IP by routing traffic through intermediary servers.
• Benefits:
  • Anonymity – Hides your real IP.
  • Geo-spoofing – Access region-locked content.
  • Multi-protocol support – Works with browsers and apps.

2. VPN (Virtual Private Network)

• Encrypts your connection and assigns a new IP address.
• Choose a reputable provider for better security.

3. Tor Browser

• Routes traffic through multiple nodes for maximum anonymity (slower but highly secure).
