class=\"brand-claim\">What is DNS?<\/h1>\n<p class=\"lead-def\"><strong>DNS<\/strong> stands for <em>Domain Name System<\/em>. It is a <strong>name resolution<\/strong> service that automatically maps the IP addresses of <a href=\"https:\/\/taismo.de\/en\/what-is\/web-server\/\">web servers<\/a> (for example &#8220;178.20.101.17&#8221;) to domain names such as &#8220;taismo.de&#8221;. People remember domain names <strong>more easily<\/strong> and more intuitively, because they usually consist of familiar words of a language and, unlike IPv4 or IPv6 addresses, are not just a random combination of letters and numbers.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/taismo.de\/wp-content\/uploads\/2026\/07\/dns.png\" width=\"1200\" height=\"675\" alt=\"DNS explained: the Domain Name System maps domain names to the IP addresses of web servers\" loading=\"lazy\"><\/figure>\n<h2 id=\"how-does-dns-work\">How does DNS work?<\/h2>\n<p>Put simply, DNS works like a <strong>phone book<\/strong>.<\/p>\n<p><strong>Instead of<\/strong><\/p>\n<table>\n<tbody>\n<tr>\n<td>Name<\/td>\n<td>Phone number<\/td>\n<\/tr>\n<tr>\n<td>Miller<\/td>\n<td>089\/123456<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>the <strong>database of the DNS service<\/strong> holds<\/p>\n<table>\n<tbody>\n<tr>\n<td>Domain name of a website<\/td>\n<td>IP address of the web server<\/td>\n<\/tr>\n<tr>\n<td>taismo.de<\/td>\n<td>178.20.101.17<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>When you type a domain name into a <strong>browser<\/strong>, the request goes to the <strong>DNS<\/strong> first. The service searches its database for a <strong>matching entry<\/strong>. If it finds one, it translates the domain name and passes the request on to the corresponding <strong>web server<\/strong>. The <strong>website<\/strong> that sits in a directory on that server is then displayed. Every <a href=\"https:\/\/taismo.de\/en\/what-is\/http-statuscode\/\">HTTP status code<\/a> you later see in the browser comes from that server, not from the DNS.<\/p>\n<h2 id=\"why-you-need-dns\">Why do you need DNS?<\/h2>\n<p>When you build a new website, you first have to buy the domain you want, provided it is still <strong>available<\/strong>, from a <strong>domain registry<\/strong>, usually for a fee. After that you need an <strong>entry on a DNS server<\/strong> that ties the domain name to a server address and a directory. Most <strong><a href=\"https:\/\/taismo.de\/en\/webdesign\/\">web hosting providers<\/a><\/strong> and domain name registrars offer services that let you create these entries directly on their own platform.<\/p>\n<p>If you want to move your website from one web server to another, all that has to change after the move is the <strong>DNS entry<\/strong>.<\/p>\n<p>Do you need <a href=\"https:\/\/taismo.de\/en\/request\/\">help with your website migration<\/a>?<\/p>\n<\/p><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>IKI Contents How does DNS work?
