Difference between ISP and IP

When we talk about the internet, two important terms come to our mind – ISP and IP. Even though these two terms are related to each other, they have different meanings and functions.

What is an ISP?

ISP stands for Internet Service Provider. It is a company that provides internet access to users or organizations. An ISP can offer different types of internet access such as dial-up, DSL, cable, or fiber. They can also provide other services such as web hosting, email, and virtual private network (VPN).

The ISP connects the user to the internet by setting up a physical connection through cables, satellite, or wireless networks. They also provide a unique address to every device that connects to the internet, called an IP address.

What is an IP address?

An IP address, or Internet Protocol address, is a unique numerical identifier assigned to every device connected to the internet. It serves as a location identifier, allowing devices to communicate and transfer data over the internet.

There are two types of IP addresses: IPv4 and IPv6. The IPv4 addresses have a 32-bit address space and are represented in decimal form (e.g. 192.168.1.1) while IPv6 addresses have a 128-bit address space and are represented in hexadecimal form (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

Difference between ISP and IP

The main difference between ISP and IP is that ISP is a service provider that connects users to the internet, while IP is the location identifier assigned to a device connected to the internet.

In other words, ISP allows users to access the internet while IP allows devices to communicate with each other over the internet. Without an ISP, a device cannot access the internet, and without an IP address, a device cannot communicate with other devices over the internet.

Here’s a sample code in Python to get the IP address of a device:

# Import socket module
import socket      

# Get hostname
hostname = socket.gethostname()    

# Get IP address
ip_address = socket.gethostbyname(hostname)    

# Print IP address
print("IP Address:", ip_address)

Here’s a sample code in Java to get the IP address of a device:

// Import InetAddress class
import java.net.InetAddress; 

public class GetIPAddress {
   public static void main(String[] args) {
      try {
         // Get local host
         InetAddress myIP = InetAddress.getLocalHost();

         // Print IP address and hostname
         System.out.println("IP Address: " + myIP.getHostAddress());
         System.out.println("Hostname: " + myIP.getHostName());
      } 
      catch(Exception e) {
         // Print error message
         System.out.println("Error message: " + e);
      }
   }
}

Conclusion

In conclusion, ISP and IP may sound similar, but they play different roles in the internet landscape. ISP provides the service of connecting users to the internet while IP assigns a unique identifier to every device connected to the internet. Without ISP, users cannot access the internet, and without IP addresses, devices cannot communicate with each other over the internet. Understanding the difference between these two terms is crucial for anyone who wants to navigate the internet comfortably.
