//What You Need to Know about Domains and IP Address

What are Domains? IP Address? A lot of people are browsing the web each day, but they don’t know the meaning if the terms. To access a website, a user type in something into the address bar of the browser. This is known as a domain name. The browser will then connect the user to the requested website.

What are Domains?

A domain name is the structured label that connects to one specific Internet Protocol or IP address of the server where the website is hosted. For instance, www.example.com is a domain name. Domains are made of two parts, which are the actual domain name and the Top Level Domain or TLD. Some examples of TLDs include .com, .org, .net, .gov, .edu, and .info, just to name a few.

Domains are governed by the Internet Corporation for Assigned Names and Numbers or ICANN. They are in charge of creating new and maintaining existing TLDs. Individuals and companies can choose domain names and register them with a registry.

What is DNS?

Another thing that you should know is that each website is hosted on servers found across the globe. However, these servers are not recognized through their domain names. Instead, they are known by their IP address. An IP address looks something like 123.45.678.90. If you enter the IP address into the browser, you will end up on the website.

Domain Name System or DNS serves as a database of IP addresses and their corresponding domain names. The DNS server is also known as name servers. The purpose of DNS is to make browsing simpler. There’s no need to remember all the number sequences in order to access a website. All you need to enter is the domain name, and the browser will be the one that looking for its IP address in the DNS system.

If you want to go to a certain website, the browser will first go to the root DNS records. Once the browser finds the actual IP address of the domain name, the website will load. This process just takes a couple of millisecond. It might seem complicated, but it is much better than memorizing a couple of numbers in order to go to a website.

To sum it up, the IP address is the true identifier of the server that hosts the website. The domain name is the redirector that helps internet users find the right web server. At any time of the day, there are millions of IP addresses active that represent servers and internet users.

In the early days of the internet, each computer has a fixed IP address. However, this is impossible today as the number of internet users grown to millions. At present ISPs lend IP addresses to users from a pool of numbers. This is known as dynamic IP addressing.

These are the things that you need to know about domains, IP address, and name servers. Hopefully, you are no longer confused about the terms that allow you to access your favorite websites online.
