How Internet Addresses Work: DNS And IP Address
Updated On June 4, 2021 | by Ankit
Interrelation of IP and DNS
Have you ever thought of how we get on a website? Why do the website addresses look like we see them? What is my IP? How can you increase the Internet speed quickly and easily, protecting yourself in the network for free? And what are we going to do when the addresses finish? Now we will speak about DNS and IP address.
What is the IP Address?
Each electronic device that is connecting to the Internet has its Internet Protocol (IP). This set of numbers separated by dots identifies the computer or mobile gadget in the world net and serves as an essential part of the TCP/IP protocol.
Check IP each time when you have technical issues. Inexperienced Internet users wonder what is my IP address and how to check it. It takes a second when using IP checker tools. Also, you can ask Google what is my IP by typing the request in the search line.
VPN services can be your IP checker as well. It can hide your IP, so you will enjoy anonymous web surfing. Consider all advantages of the services while using a trial-free version.
What is DNS
We all live with some misconception in our minds. Opening any browser, we see the address bar on the top. What if I tell you that the website addresses that we know, e.g., youtube.com, yahoo.com, etc., are not the addresses but the domain names. People can remember the website names easier when they see letters. But in fact, these consist of numerals only.
It means that the addresses on the Internet work as a phone book. To avoid remembering the numbers, we give a name to the contact on our mobile phones. The same happens with websites.
How do the networks «understand» that we want to enter a particular website when we type its name? A long time ago, when the Internet speed was at the developmental stage, the file «host» served as a storage for IP address and DNS. The more websites a user visited, the bigger the host file was becoming. It caused various conflicts of the names.
In 1983, Paul Mockapetris designed another system: automatized, decentralized, and reliable. It has got the name the system of domain names or DNS. Let’s deal with what it means.
How do IP Address and DNS Work Together?
Each domain can interact with more than one IP address. Some websites have myriad IP addresses that interact with one domain name. That significantly economizes the time for the response since millions, or even billions of users, reach the same site at the moment as you do.
When your electronic device is looking for an IP address associated with a domain name, it sends the request to DNS (recursive resolver). It starts the sequence of queries that lead to the link for transferring to the necessary IP address.
What is the Difference Between DNS and IP?
IP address and DNS are technically separate. Being a unique identifier for a specific path to a host on a network, IP represents an endpoint. While IP belongs to each computer to identify on a given network, DNS converts alphabetic links into the IP of a server for hosting services.
The difference between DNS and IP is evident. An example of an IP address (localhost) is 139.0.0.2. It might change within some time, so to know it, you should check IP according to your needs. Using the www.example.com URL, example.com is the domain name, and www is the hostname. DNS transfigures www.example.com into an IP address. When an Internet user wants to open a webpage, a conversion must happen between what the user writes in the browser line into an IP address required to locate the www.example.com site.
At this point, you should get a general understanding that DNS is and what a nameserver is, as well as being familiar with technical options relating to IP addresses. For in-depth research, you should dive into the fantastic world of DNS. There is much more to study.
The battle DNS VS IP address ends with a 1:1 result as these both are crucial points while exploring the Internet.
