Role of an IP Address and Its Working

The tremendous development in the field of IT (Internet Technology) may shock you today. It is not a difficult task to find someone anywhere on the globe using IT skills. For this purpose, a unique device address is used called an IP address. Splitting up the word into two parts; the term IP stands for Internet Protocol and the term address represents a unique set of characters.

Every device which is connected to the internet in any way has this address. And each device has its unique address. In a world full of technology every one of us is connected to the internet somehow. Either it is through our cell phone or our personal computers (PCs).

In this way, it is very easy to find out a person’s location using his/her device’s IP address. An IP address contains information about the region, country name, postal code, and even the time zone which shockingly can lead anyone to your doorstep. You can find out the IP address and location of your device using the link what is my IP.

What is the role of an IP address?

After understanding the basic definition of IP address now we shall move towards the role of IP address. In this article, you will also learn that how an IP address work and what is the difference between IP version 4 and IP version 6?

To help you understand the role of IP address I will try my best to explain it in simple words. Let us start to form a basic example. What would you mention in the letter if you want to send it to your friend? Obviously, there are two types of addresses we have to mention on a mailbox. One of them is the receiver’s address and the other one is the sender’s address. The receiver’s address will be your friend’s address to which you want to send the letter. And in sender’s address, you will write your address.

IP address works in the same way. Whenever you send an email or information over the internet it consists of the source address and the destination address. There is a little difference in digital information sharing that you can send it to various devices simultaneously. In this case, there will be more than one destination address.

How does it work?

Now the question is how the information is transferred accurately to that specific device. For this purpose there are devices like routers in the network model. These routers are responsible for finding the device with the same address as that of the destination address. Once the router in the network model finds the destination device the message or information is delivered to it accurately.

192.168.1.1 is an IP address for a router, which, if used to connect to the Internet, all computers and devices that access the Internet through this router will use this address as their default gateway.

Talking about how much time it will take to send information or a message over a network depends on the network speed. In most cases, we use the internet as a network for information sharing. For a detailed speed test of your network, an online platform is suggested here.

Further explaining that basic example; during a mail we know which particular word stands for country, which one is for the city is which one is for the street. Similarly, IP addresses have two parts; there is a part that represents the network and there is another part that represents the host device.

As we proceed in the discussion “Role of an IP Address and It’s Working” we find two types of IP addresses. One of which is IP version 4 and the other is IP version 6 which are also referred simply as IPv4 and IPv6. There is a very simple and basic difference between these two.

IP version 4 is an older technology. It uses a 32-bit scheme to store addresses in it. As we all know that a bit is a combination of zero (0) and one (1). In this way, there are 2 to the power of 32 (2^32) address spaces in this version. You may think that it’s enough to hold up all the addresses but it’s not true. Actually, over time we ran out of the address spaces in version 4. So latest versions of IP address; IP version 6 was introduced to provide with more address spaces. This version works with a 128-bit scheme. Now 2 to the power of 128 (2^128) gives us a number large enough to handle our IP addresses.
