This is why the DNS is often compared to a telephone directory that associates&nbsp;persons&nbsp;names (equivalent to domains) with telephone numbers (equivalent to IP addresses).<\/p>\n\n\n\n<p>If web users want to go to a given website, they will not type in the IP address,\u00a0as\u00a0it is too complex. Instead, they will type in their browser the domain name that has been assigned to the website. This starts a process of decoding the website the user is looking for and routing his traffic to the right web server. The nameserver, acting in the middle of this process, holds all of the records for which websites are located and where, as it is able to translate the domain name into an IP address.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"583\" src=\"https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-1024x583.jpg\" alt=\"\" class=\"wp-image-13879\" srcset=\"https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-1024x583.jpg 1024w, https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-300x171.jpg 300w, https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-768x437.jpg 768w, https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-50x28.jpg 50w, https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-60x34.jpg 60w, https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN-100x57.jpg 100w, https:\/\/kb.n0c.com\/wp-content\/uploads\/2024\/01\/DNS_EN.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><meta charset=\"utf-8\"><em>The&nbsp;DNS System<\/em><\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p><br>The DNS makes it possible, in particular, to reach the web server of a specific domain or a mail server to which a user wishes to send an e-mail.&nbsp;<\/p>\n\n\n\n<p><strong><meta charset=\"utf-8\"><\/strong>AFNIC&nbsp;has published a short video explaining the&nbsp;Domain Name System (DNS)&nbsp;very well in French: <a href=\"https:\/\/www.youtube.com\/watch?v=dcIrB8qRCbA&amp;feature=youtu.be\">https:\/\/www.youtube.com\/watch?v=dcIrB8qRCbA&amp;feature=youtu.be<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A website is located on a server identified by an IP address.
