Domain Name System is a translator for the internet. When you type in a website name, DNS helps your computer understand where that website is located. Moreover, it provides a unique number called an IP address, such as 192.0.2.44. In short, it turns a familiar address into the exact coordinates your computer needs to find and connect to the right place on the internet.
The internet has its unique address. These addresses are like phone numbers but for computers, called IP addresses. Now, when you want to visit a website, you don't have to remember and type in a complicated number. Instead, you can use a name, like example.com, and still get to the right place.
So, DNS is a translator that turns these easy names into the actual computer numbers. Amazon Route 53 is one of these helpful translators, and it's all over the world to ensure things run smoothly. It ensures your computer knows which number to connect to when you type in a website name or domain. These translation requests are called queries.
Now, let's talk about two parts of domain name system services: Authoritative DNS and Recursive DNS.
Authoritative DNS is in charge of keeping track of the necessary addresses (IP addresses) for websites. Moreover, it is the one with the final say and provides the answer. When you want to visit a website, you can’t always ask the Authoritative DNS directly. Instead, you go to the assistant, a resolver, who knows how to get the information for you. The resolver might already have the website details stored (cached). Moreover, if so, it quickly gives you the answer. But if not, it reaches out to the Authoritative DNS to find where to go.
So, Authoritative DNS is the big decision-maker, and Recursive DNS is the friendly assistant that helps you find your way around the internet.
Alright, let's know the popular domain name system servers when you open a webpage.
This step-by-step teamwork ensures that when you type a website name, your computer can quickly find the right place on the internet.
Follow the below steps to know how your computer finds a website using domain name system when you type its name in the browser.
Finally, the DNS hosting resolver keeps a note of this address for a while.
So, when you type a nice and easy website name (like 'www.example.com') into your computer or phone, DNS Lookup is a helpful process. As a result, it takes that name and figures out the genuine computer number (IP Address) it needs to talk to on the web. It turns human-friendly names into the digital addresses that computers use to chat with each other online. So, the Domain Name System is the language interpreter. However, it makes sure everyone online can understand each other and find their way around.
When you want to access a website or use an online service, DNS Resolver plays a crucial role. It is responsible for the locating process of the correct address for the website, which is also known as DNS Lookup or DNS Resolution.
Let's talk about the three types of domain name system Queries when they're trying to find something on the internet.
So, these queries are like different ways of asking questions in the DNS world. However, it depends on what you're looking for and how much info you already have in your computer's memory.
DNS Caching looks up addresses for websites. Instead of asking every time, it remembers the addresses it found before and keeps them in a little memory folder. It stores the domain names and IP addresses it has seen before, so it doesn't have to search over again.
By remembering this info, your computer can skip some steps the next time you visit a website. So, DNS Caching is like your computer's little helper, making sure things happen faster.
Every time you visit a website, send an email, or even look at a picture on social media, the DNS plays a vital role. However, it turns easy-to-remember names (like icann.org) into the IP addresses that computers use to talk to each other.
Now, when you use the Internet on your phone or any device, it all starts with the domain name system. Let's say you type a website name into your browser. Your device's operating system has a little helper called a 'stub resolver.' However, this starts the process of figuring out the website's address by asking a more knowledgeable friend, known as a 'recursive resolver.' Many large networks have these smart friends to handle requests from devices on their network.
The following section will elaborate on the list of various DNS security solutions that every individual must know.
To sum it up, the Domain Name System (DNS) plays a necessary role in the internet. As a result, it makes the internet run super smoothly. It's a language translator for computers, turning easy-to-remember website names into unique numbers they use to talk to each other. This role is essential for everything we do online, like checking websites or sending emails. Our devices can easily find and chat with each other across the world on the internet.
