This process is called <strong>DNS resolution<\/strong>.<\/p>\n\n\n\n<p>In practice, this means that rather than remembering the IP address of a website, you only need to remember its <strong>domain name<\/strong>which will be automatically translated into an IP address to access the server hosting the site.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"role-des-dns\">Role of DNS<\/h2>\n\n\n\n<p>DNS does more than just point domain names to IP addresses. It can also contain other essential information, notably for managing <strong>emails<\/strong> (like MX records for sending and receiving e-mail). In addition, DNS can be used to create <strong>sub-domains<\/strong> by adding specific entries in the DNS zone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"les-composants-du-dns\">DNS components<\/h2>\n\n\n\n<p>DNS scoring management is based on two key elements:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong><a href=\"\/en\/doc\/dns\/ns-name-servers\/\">Name servers (NS)<\/a>)<\/strong> :<br>These are the DNS servers <strong>authoritarian<\/strong> for a domain.
