how to know Android phone,computer and website ip address in hindi

In the world of networking, understanding IP addresses is essential. Every device that connects to the internet—be it a computer, smartphone, router, or smart home device—has a unique IP address assigned to it. But what is an IP address, how does it function, and why is it so important? In this blog post, we will clarify what IP addresses are, explain how they work, and discuss the different types.

What is an IP Address?

An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a network. It allows devices to identify each other and communicate over the internet or within a local network. Think of it like a home address for your device on the internet, helping data find its way to the correct destination, just like how a postal service uses a home address to deliver letters and packages.

The IP address serves two primary purposes:

  1. Identifying the host or device on the network.
  2. Locating the device within the network (much like a home address tells where a house is located).

The Two Types of IP Addresses

There are two main types of IP addresses you’ll encounter: IPv4 and IPv6. Let’s break them down.

1. IPv4 (Internet Protocol version 4)

IPv4 is the most widely used version of the Internet Protocol and is the fourth version of the protocol. It uses a 32-bit address scheme, meaning it consists of four sets of numbers (each ranging from 0 to 255), separated by periods. For example, an IPv4 address might look like:

192.168.1.1

Each of the four numbers is called an octet because it’s an 8-bit value. This means there are a total of 2^32 (approximately 4.3 billion) unique IPv4 addresses available. However, due to the rapid expansion of the internet and the growing number of connected devices, IPv4 addresses are running out.

2. IPv6 (Internet Protocol version 6)

IPv6 is the newer version of the Internet Protocol, introduced to deal with the limitations of IPv4, especially the shortage of available addresses. IPv6 uses a 128-bit address scheme, which allows for a vastly larger pool of unique addresses. IPv6 can support 2^128 unique IP addresses—enough to assign an IP to every device on the planet (and more).

IPv6 addresses are written as eight groups of four hexadecimal digits, separated by colons, like so:

2001:0db8:85a3:0000:0000:8a2e:0370:7334

While IPv6 adoption is still growing, it is the future of internet addressing and will eventually replace IPv4 as more devices require connections.

What is Static vs. Dynamic IP Addresses?

IP addresses are also categorized into two types based on whether they are fixed or changeable:

1. Static IP Address

A static IP address is an address that is permanently assigned to a device or server and doesn’t change. These addresses are often used for websites, email servers, or services that need a consistent point of contact.

  • Advantages:
  • Reliable for hosting services like websites and email servers.
  • Easier to configure certain network devices and services, such as remote access and VPNs.
  • Disadvantages:
  • It’s easier for hackers to target static IP addresses because they remain the same over time.
  • It can be more expensive because ISPs typically charge extra for static IP addresses.

2. Dynamic IP Address

A dynamic IP address is temporarily assigned to a device by a Dynamic Host Configuration Protocol (DHCP) server, usually by your Internet Service Provider (ISP) or your router in a home network. These addresses change periodically (every time you connect to the internet, or at set intervals).

  • Advantages:
    • More secure: Dynamic IP addresses change regularly, making it harder for hackers to track or target a device.
    • Cost-effective: ISPs generally provide dynamic IPs as part of their standard service.
  • Disadvantages:
    • Not ideal for hosting websites or services that require a fixed point of contact.
    • May cause some connectivity issues if a specific address is needed for certain applications.

What is Public vs. Private IP Addresses?

IP addresses can also be classified as public or private, depending on whether they are visible on the internet or confined to a local network.

1. Public IP Address

A public IP address is assigned to your network by your ISP and is visible to the public internet. This is the address that websites and other online services use to identify your device or network. Each time you connect to the internet, your router or modem is assigned a public IP address.

  • Purpose: Public IPs are used to route data between your device and the internet. For example, when you visit a website, your device’s public IP address communicates with the website’s server to request the page.
  • How it works: Multiple devices in your home or office (such as computers, phones, and smart TVs) will share a single public IP address via your router using NAT (Network Address Translation).

2. Private IP Address

A private IP address is used within a local network (LAN), such as your home or office. These addresses are not routed on the public internet and are used to identify devices within your network. Private IP addresses are often assigned to each device in a home or office network by your router.

Common ranges for private IP addresses are:

  • 192.168.0.0 to 192.168.255.255
  • 10.0.0.0 to 10.255.255.255
  • 172.16.0.0 to 172.31.255.255
  • Purpose: Private IPs are used to communicate between devices within the same local network. They allow for file sharing, printing, and other local tasks without needing a public IP for every device.
  • How it works: Devices with private IP addresses access the internet through a NAT-enabled router, which translates the private IP to the public IP when requesting data from the internet.

How Do IP Addresses Work?

Every time you access a website or use an online service, your device sends data packets across the internet. These data packets contain the IP address of the sender (your device) and the receiver (the website’s server).

Here’s how the process works:

  1. Request: You type a website URL (e.g., www.example.com) into your browser.
  2. DNS Lookup: The browser sends a request to a DNS server (Domain Name System), which translates the human-readable domain name into an IP address.
  3. Data Transmission: The browser then sends a request to the server hosting the website, using the server’s IP address.
  4. Response: The server sends the website’s data (HTML, images, etc.) back to your device’s IP address, allowing you to view the website in your browser.

This process happens in a fraction of a second, ensuring seamless access to web pages and online services.

How Can You Find Your IP Address?

To find your device’s IP address, you can follow these simple steps:

1. Find Your Public IP Address

  • Google search: Simply search “What is my IP?” in Google, and it will display your public IP address.
  • Online services: Websites like WhatIsMyIP.com also display your public IP address.

2. Find Your Private IP Address (on Windows)

  1. Open the Command Prompt.
  2. Type ipconfig and press Enter.
  3. Look for the line that says “IPv4 Address”, which will display your private IP address.

3. Find Your Private IP Address (on Mac)

  1. Click on the Apple Menu and select System Preferences.
  2. Choose Network, and select your active connection (Wi-Fi or Ethernet).
  3. Your IP address will be displayed under the Status section.

Conclusion

IP addresses are essential for internet communication, enabling devices to exchange data. They exist in various formats (IPv4 and IPv6) and types (static and dynamic), serving both public and private purposes. Grasping how IP addresses function and impact online communication is crucial for network setup, troubleshooting, and ensuring privacy and security in today’s digital world.
