Why? The reason being, the internet cannot understand names. The machine doesn\u2019t understand the letters or the words. So, to make the machine understand what you are looking for &#8211; DNS translates the domain (<a href=\"https:\/\/www.milesweb.in\/\" target=\"_blank\" rel=\"noopener\">https:\/\/www.milesweb.in\/<\/a>) into an IP Address.<\/p>\n\n\n\n<p>As the IP Address is being generated, the browser redirects you to the web resources. Just how you provide the address to the driver, and the driver searches the route and drops you at the place.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"445\" src=\"https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-32.jpg\" alt=\"how dns works dns server full form dns records example types of ip address \" class=\"wp-image-14848\" srcset=\"https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-32.jpg 800w, https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-32-300x167.jpg 300w, https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-32-768x427.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Still Confused?

That is why IP addresses make things simple &amp; efficient for the browser and the visitor.<\/p>\n\n\n\n<p><strong>Related: <a href=\"https:\/\/www.milesweb.in\/blog\/hosting\/why-does-your-ip-address-gets-blacklisted\/\" target=\"_blank\" rel=\"noopener\">Why Does Your IP Address Gets Backlisted<\/a>.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"WPT2WPTheme\">Types of DNS Query &#038; Servers<\/h2>\n\n\n\n<p>As I mentioned, there are processes that are running in the background just to fetch you results. These are the types of DNS queries or servers that are doing their job.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">&#8211; DNS Resolver<\/h3>\n\n\n\n<p>A DNS Resolver takes a client query and searches through its books to understand whether the page the client is looking for exists or not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">&#8211; Root Server <\/h3>\n\n\n\n<p>Root server receives DNS resolver\u2019s request and translates domains into its IP Addresses before returning it to the DNS Resolver to let it know the results of its request.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"445\" src=\"https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-33.jpg\" alt=\" tld top level domain nameserver dns root server MilesWeb\" class=\"wp-image-14849\" srcset=\"https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-33.jpg 800w, https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-33-300x167.jpg 300w, https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-33-768x427.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">&#8211; TLD Server<\/h3>\n\n\n\n<p>Later, the resolver requests the TLD server for the top-level domain of the client\u2019s request &#8211; meaning \u2018.com\u2019, .in, .org, etc., and returns the result to the resolver server.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">&#8211; Authoritative Nameserver<\/h3>\n\n\n\n<p>Finally, the Domain Name Server Resolver requests an authoritative nameserver for the specific IP Address of the client\u2019s query. Basically, authoritative name servers store individual IP Addresses, whereas root servers point to the storage of different IP Addresses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">&#8211; DNS Root Servers<\/h3>\n\n\n\n<p>There are around 13 root servers that help the DNS fetch results and provide them to the user. These root servers store all the information of domains and their IP Addresses. They act like a shelf that has all books with respective genres.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"WPT3WPTheme\">Understanding DNS Records<\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"445\" src=\"https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-34.jpg\" alt=\"what is dns and its working\" class=\"wp-image-14853\" srcset=\"https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-34.jpg 800w, https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-34-300x167.jpg 300w, https:\/\/www.milesweb.in\/blog\/wp-content\/uploads\/2021\/09\/Blog-Feature-Image-PR-34-768x427.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Below are the key <strong>DNS Record types<\/strong> that need special consideration.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A Records<\/strong> &#8211; A record is used to point your domain to an IPv4 address. It points the domain to its respective web server.<\/li>\n\n\n\n<li><strong>CNAME Records<\/strong> &#8211; These records are used to point a subdomain to its primary domain.<\/li>\n\n\n\n<li><strong>MX Records<\/strong> &#8211; These records are associated with an email service. When you wish to have an email with @yourdomain.com, MX records are used to deliver the emails.<\/li>\n\n\n\n<li><strong>TXT Records<\/strong> &#8211; These records ensure seamless email delivery and robust <strong>DNS security<\/strong> to block spam emails.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"WPT4WPTheme\">How To Save Yourself From DNS Attacks?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Keep a check of all the websites you visit<\/li>\n\n\n\n<li>Install antivirus software that will block fraudulent acts<\/li>\n\n\n\n<li>Check whether the website has an <a href=\"https:\/\/www.milesweb.in\/ssl-certificates.php\">SSL Certificate<\/a> or \u2018HTTPS in case<\/li>\n\n\n\n<li>Do not avoid any message that you get on visiting irregular websites<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"WPT5WPTheme\">DNS Servers Can Be Set According To Devices<\/h2>\n\n\n\n<p>The devices you use can have specific DNS servers. That means each device you use will use its separate DNS.<\/p>\n\n\n\n<p>DNS also configures its settings to the closest device. Meaning &#8211; the wifi router you use has one set of DNS Servers. So, every time you connect devices to WIFI, they will use the router&#8217;s DNS settings.<\/p>\n\n\n\n<p>In case the PC or the laptop has its separate settings, then the laptop or PC will run on different DNS than other devices used to connect to the router.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"WPT6WPTheme\">Understanding DNS Caching<\/h2>\n\n\n\n<p><a href=\"https:\/\/www.milesweb.in\/blog\/hosting\/an-informative-guide-on-the-process-of-caching-in-web-hosting\/\">DNS caching in web hosting<\/a>&nbsp;is one of the ways to provide requested results faster.<\/p>\n\n\n\n<p>That means when the client requests a web page several processes occur in the background. Which includes the types of queries we talked about in the above section.<\/p>\n\n\n\n<p>So, to not do the entire query process step by step and provide the results faster, DNS Caching stores the data connecting to the requesting client. The next time they request the same query, the DNS will return the request without having to go through the entire DNS lookup process.<\/p>\n\n\n\n<p><strong>DNS cache<\/strong> enables quick data access from different locations with temporary provisions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"WPT7WPTheme\">Are DNS Requests Safe &#038; Private?<\/h2>\n\n\n\n<p>DNS transfers the query in plain text, which then travels over the internet. So, the person who intercepts the request can know your activity.<\/p>\n\n\n\n<p>These queries are not generally encrypted. Meaning, even if you use the resolver server, it is still not secured.<\/p>\n\n\n\n<p>However, DNS over HTTPS and TLS can be used to encrypt the DNS queries and protect them from stalkers willing to read the activities.<\/p>\n\n\n\n<div class=\"vlt-box \">\n<div class=\"box-title\" style=\"background:#D5EAFF; color:#000\">Summing Up \u2013<\/div>\n<div class=\"box-content\" >\n<p>Understanding DNS and its functionality may be a challenge for many, but certainly not after reading this blog. We\u2019ve ensured DNS explained simply and straightforwardly, making it easier for users new to this.<\/p>\n<p>It helps users land on a webpage by translating the IP Addresses of domains. And the translated IP Addresses are provided by the nameservers who store the database of domains with specific internet protocols.<\/p>\n<p>The processes take place step-by-step. But to your eyes, it is only a one-step thing so that you can be redirected to the web resources with ease.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"vlt-box \">\n<h2 class=\"box-title\" style=\"background:#D5EAFF; color:#000\" id=\"WPT8WPTheme\">FAQs<\/h2>\n<div class=\"box-content\" >\n<h3 class=\"box-title\" style=\"background:#D5EAFF; color:#000\">What is a domain name system (DNS), and how DNS work?<\/h3>\n<p>The DNS follows a hierarchical mechanism that connects domain names to unique IP addresses. It translates user-friendly domain names into machine-supportive IP addresses. They play a role in ensuring that online traffic is directed to the right servers. It also distributes the incoming traffic towards different servers for load balancing.<\/p>\n<h3 class=\"box-title\" style=\"background:#D5EAFF; color:#000\">What are the main DNS record types, and what\u2019s their role?<\/h3>\n<p>The domain\u2019s working framework includes several DNS record types. Each DNS record is created for a specific role. MX records define the server authority for domain-specific email systems. A record has a role in mapping a domain to an IPv4 address, whereas a CAA Record allocates the authoritative controls to issuing SSL certificates.<\/p>\n<h3 class=\"box-title\" style=\"background:#D5EAFF; color:#000\">Why is DNS a fundamental part of network infrastructure?<\/h3>\n<p>DNS is central to the activity of converting unique domain names into specific IP addresses. These IP addresses are crucial for systems to read user requests for a specific website on a network. It adds a strong security layer and ensures seamless navigation.<\/p>\n<h3 class=\"box-title\" style=\"background:#D5EAFF; color:#000\">How can I find my DNS server?<\/h3>\n<p>Windows users: Command Prompt > type ipconfig \/all. macOS users: System Preferences>Network> select connection> Advanced. Linux users: Terminal> cat \/etc\/resolv.conf.<\/p>\n<h3 class=\"box-title\" style=\"background:#D5EAFF; color:#000\">What does a DNS lookup mean?<\/h3>\n<p>In simple terms, a DNS lookup involves querying a DNS server to locate the exact IP address of a website. When a DND server receives a user request, it converts the domain name. It provides a specific IP address that helps in presenting the result of the intended website.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>As\u00a0 a beginner it\u2019s crucial to gain a comprehensive understanding of what is DNS and how it functions.
