If you’ve ever had to configure a domain name<\/a> or move a website from one hosting provider to another, you’ve probably come across nameservers<\/strong>. You may have wondered: \u2018What exactly are they? How do they work? And how do I know if everything is configured correctly?\u2019<\/em> Don’t worry, here at Hostingfy we’ll explain everything in a simple and practical way. We’ll look at what a nameserver is<\/strong>, how it works<\/strong>, what it’s used for<\/strong>, and how you can check that it’s working properly<\/strong>.<\/p>\n\n\n\n

What is a nameserver?<\/h2>\n\n\n\n

Nameservers are a fundamental part of how the Internet works, but they often go unnoticed or are confused with other parts.<\/p>\n\n\n\n

Definition<\/h3>\n\n\n\n

A nameserver<\/strong> is a type of DNS (Domain Name System) server<\/strong> that translates domain names (such as www.tuosito.it<\/code>) into IP addresses<\/strong>, which are the numerical identifiers of machines connected to the Internet. In practice, every time you type a URL into your browser, your computer contacts a nameserver to find out which IP address corresponds to that name.<\/p>\n\n\n\n

What are they used for<\/h3>\n\n\n\n

Their purpose is to allow users to reach a website by typing in an easy-to-remember name<\/strong>, instead of having to enter a long string of numbers. The nameserver therefore represents the link between the domain and the hosting<\/strong>, i.e. the space where your website is hosted.<\/p>\n\n\n\n

Where are they located<\/h3>\n\n\n\n

Usually, nameservers are managed by the hosting provider<\/a><\/strong> (such as Hostingfy) or by the domain registrar<\/strong>. Each domain has one or more nameservers (usually at least two) that work in pairs to ensure reliability and continuity of service.<\/p>\n\n\n\n

How a nameserver works in DNS<\/h2>\n\n\n\n

Now that we’ve seen what a nameserver is, let’s get to the heart of the matter: how does it work? Let’s see how it fits into the domain name resolution process.<\/p>\n\n\n\n

Its role in the DNS system<\/h3>\n\n\n\n

The Domain Name System (DNS)<\/strong> is like a giant phone book for the Internet. When you type www.google.com<\/code>, your device queries the DNS<\/strong> to find out which IP address it needs to connect to. Nameservers participate in this communication chain and are responsible for managing the DNS zones<\/strong> associated with a specific domain.<\/p>\n\n\n\n

DNS resolution step by step<\/h3>\n\n\n\n

Here’s a quick overview of what happens when you browse a website:<\/p>\n\n\n\n

    \n
  1. The browser asks the DNS system for the domain’s IP address.<\/li>\n\n\n\n
  2. The DNS resolver (usually provided by your Internet service provider) contacts a root server<\/strong>.<\/li>\n\n\n\n
  3. The root server points to an authoritative nameserver<\/strong> for the top-level domain (such as .it<\/code> or .com<\/code>).<\/li>\n\n\n\n
  4. This points to the nameservers for the specific domain<\/strong>.<\/li>\n\n\n\n
  5. The nameserver responds with the correct IP address.<\/li>\n\n\n\n
  6. The browser connects to the website via that address.<\/li>\n<\/ol>\n\n\n\n

    All this happens in a fraction of a second<\/strong> and no one notices.<\/p>\n\n\n\n

    Authoritative vs non-authoritative nameservers<\/h3>\n\n\n\n

    Another important concept is the distinction between authoritative<\/strong> and non-authoritative<\/strong> nameservers. The former are those that directly manage DNS information<\/strong> for a specific domain, while the latter are more like \u201cmessengers\u201d that collect and transmit information from other sources.<\/p>\n\n\n\n

    How to check a domain’s nameservers<\/h2>\n\n\n\n

    Let’s get to the practical part: do you want to know which nameservers are associated with your domain<\/strong>, or do you want to check if the configuration is correct? There are several ways to do this, even without being a programming expert.<\/p>\n\n\n\n

    Why check<\/h3>\n\n\n\n
