Technically, however, the terms describe different things.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>Domain<\/strong> is the unique address under which an internet offering can be reached. A <strong>Website<\/strong> consists of the actual content and files served via a web server. A <strong>URL<\/strong> on the other hand designates the specific address of a particular resource \u2013 for example, an individual page, an image, or a file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing the differences is especially helpful when registering a domain, migrating a website, changing DNS settings, or investigating a technical issue with your online presence.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Briefly explained:<\/strong> The domain is the address, the website is the online presence accessible via it, and a URL describes the exact location of a specific resource.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">What is a domain?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A domain is a human-readable name within the Domain Name System (DNS). It makes it possible to access internet services via names like <code>curiaweb.ch<\/code> to address, instead of having to memorize the underlying technical addresses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A typical domain looks like this, for example:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>meine-firma.ch<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this example, it consists of two essential components:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>my company<\/code> is the name within the selected domain extension.<\/li>\n\n\n\n<li><code>.ch<\/code> is the top-level domain (TLD).<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Further examples of top-level domains are <code>.com<\/code>, <code>.de<\/code>, <code>.org<\/code> or <code>.swiss<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We explain in more detail what a TLD is and what function it has within the Domain Name System at <a href=\"\/en\/help\/domains-dns\/top-level-domain-tld-explained\/\">What is a top-level domain (TLD)?<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A domain is not yet a website<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Registering a domain does not automatically create a website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, you can <code>meine-firma.ch<\/code> register without any content already existing under this address. The domain then exists, but it still needs to be determined which internet services should be accessible through it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For visitors to be able to access a website, the domain must point via DNS to the appropriate hosting infrastructure. That is where the website's content is located or created.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simply put, the DNS takes on the task of connecting domain names with the technical destinations responsible for the respective service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We explain how this process works at <a href=\"\/en\/help\/domains-dns\/dns-simply-explained\/\">DNS simply explained: How the Domain Name System works<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a website?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A website is the actual internet presence. It can consist of a single page or many interconnected pages and resources.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This may include, for example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Texts and headings<\/li>\n\n\n\n<li>Images and graphics<\/li>\n\n\n\n<li>Stylesheets for the design<\/li>\n\n\n\n<li>JavaScript files<\/li>\n\n\n\n<li>Downloads and Documents<\/li>\n\n\n\n<li>Forms<\/li>\n\n\n\n<li>Database contents<\/li>\n\n\n\n<li>Blog posts<\/li>\n\n\n\n<li>Shop and product pages<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">With a content management system like WordPress, a lot of content is additionally stored in a database and processed dynamically when a page is called.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The website requires a hosting environment or a web server that provides the requested content.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Domain and hosting are two different things<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Domain and hosting are often ordered together, but they are technically separate components.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The domain provides the name or address. Among other things, web hosting provides storage space and server services for the website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a domain does not necessarily have to be registered with the same provider where the website is hosted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, you can manage a domain with an external registrar and connect it to your CURIAWEB hosting via name servers or DNS records.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We explain how this works at <a href=\"\/en\/help\/domains-dns\/domain-bei-anderem-anbieter-mit-curiaweb-hosting-verbinden\/\">Keep domain with another registrar and connect to CURIAWEB Hosting<\/a>.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Important:<\/strong> When you switch web hosting, it does not automatically mean that the domain also has to be transferred to another registrar. Hosting changes and domain transfers are technically different processes.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">What is a URL?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">URL stands for <strong>Uniform Resource Locator<\/strong>. A URL describes the address of a specific resource on the internet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a complete URL can look like this:<\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/www.meine-firma.ch\/produkte\/webhosting\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">While <code>meine-firma.ch<\/code> the domain describes the complete URL in more detail, specifying which resource should be accessed and how it is addressed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How is a URL structured?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Let us look at this example:<\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/www.meine-firma.ch\/produkte\/webhosting\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The most important components are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><code>https:\/\/<\/code><\/strong><br>This is the protocol or URL scheme used. HTTPS stands for HTTP over an encrypted TLS connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><code>www<\/code><\/strong><br>This is a hostname or, in this case, a name subordinate to the domain. Technically, <code>www.meine-firma.ch<\/code> not identical to <code>meine-firma.ch<\/code>, even though both often lead to the same website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><code>meine-firma.ch<\/code><\/strong><br>This is the domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><code>\/products\/webhosting\/<\/code><\/strong><br>This is the path to the requested resource within the website.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A URL can contain further components<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to the scheme, hostname, and path, a URL can contain further information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An example is:<\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/shop.meine-firma.ch\/produkte\/?kategorie=hosting#vergleich\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">It also contains a subdomain, a query string, and a fragment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>shop<\/code> is a child name in this example within <code>meine-firma.ch<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>?category=hosting<\/code> is a query string. Parameters can be passed to a web application via it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code># Comparison<\/code> is a fragment. For example, it can refer to a specific section within a page.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Briefly explained:<\/strong> A domain can be part of many different URLs. The domain <code>meine-firma.ch<\/code> remains the same, while protocol, hostname, path, parameters, or fragment may differ.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">What is a subdomain?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With a domain, different hostnames or subdomains can be used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>shop.meine-firma.ch<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>blog.meine-firma.ch<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>support.meine-firma.ch<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can be used to structure different services or areas under the same registered domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A subdomain is not a completely newly registered domain. It is set up within the DNS configuration of the existing domain.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is the difference between a subdomain and a subdirectory?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A subdomain like:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>shop.meine-firma.ch<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">is technically structured differently than a subdirectory like:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>meine-firma.ch\/shop\/<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the first variant, <code>shop<\/code> used as its own hostname within the DNS or the server configuration. In the second variant, the hostname remains the same and <code>\/shop\/<\/code> is merely a path within the website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Which option makes sense depends on the technical and organizational structure of the project.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is DNS and what role does it play in this?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Domain Name System connects domain names with technical information required for various internet services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, when accessing a website, it must be determined which IP address the responsible web server can be reached under.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For email services, on the other hand, other DNS records can be specified which mail servers accept messages for the domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DNS therefore does not consist only of a simple \u201edomain \u2192 website\u201c mapping. Different record types fulfill different tasks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We explain the most important DNS records such as A, AAAA, CNAME, MX, TXT, and CAA at <a href=\"\/en\/help\/domains-dns\/dns-eintraege-a-aaaa-cname-mx-txt-caa\/\">DNS Records Explained: A, AAAA, CNAME, MX, TXT, and CAA<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A domain can be used for more than one website<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Domains are not needed exclusively for websites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Different internet services can be operated under the same domain. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>www.meine-firma.ch<\/code> point to a website<\/li>\n\n\n\n<li><code>shop.meine-firma.ch<\/code> provide an online store<\/li>\n\n\n\n<li><code>mail.meine-firma.ch<\/code> be used for email services<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Which systems are actually addressed is determined by DNS and the configuration of the respective servers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Email addresses also use a domain<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For an email address like:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>info@meine-firma.ch<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">is <code>meine-firma.ch<\/code> also the domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, this does not mean that email and website necessarily have to be hosted on the same server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, MX records in the DNS can be used to determine which mail servers are responsible for incoming emails, while the website points to a different infrastructure via an A or AAAA record.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a website can be easily accessible while there is simultaneously a problem with email traffic \u2013 or vice versa.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does it mean to transfer a domain?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The expression \u201etransfer domain\u201c is not unambiguous in everyday use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can refer to various technical processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At a <strong>Domain transfer<\/strong> the administration of the domain is transferred from one registrar to another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At a <strong>Nameserver change<\/strong> whereas the registrar might remain unchanged while other nameservers will be responsible for the DNS zone in the future.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In case of a change to individual <strong>DNS records<\/strong> can in turn only point certain services to a new infrastructure without changing the registrar or nameserver.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And with a <strong>Website migration<\/strong> the actual website data and, if applicable, databases are transferred to another hosting provider.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Important:<\/strong> Domain transfer, nameserver change, DNS modification, and website migration are not the same thing. Depending on what is to be changed, a different technical process is required.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">What happens if only the domain is registered?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A registered domain can exist without a website or email service having been set up under it yet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether and what is displayed when accessing such a domain depends on its DNS and hosting configuration. For example, a placeholder page, a redirection, an error page, or no accessible website at all are possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Registration therefore initially secures the domain name. The desired services must then be set up accordingly and connected to the domain.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens with a new domain?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Following a new registration, the technical information required for use must be set up and available in the DNS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, DNS information can be cached at various locations. Therefore, changes are not necessarily visible everywhere on the internet at the exact same time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This behavior is often simply referred to as DNS propagation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We explain why DNS changes are not always immediately visible everywhere at <a href=\"\/en\/help\/domains-dns\/dns-propagation-erklaert\/\">DNS Propagation Explained: Why Changes Can Take Time<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Domain, URL and website using an example<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Let's take as an example:<\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/www.meine-firma.ch\/kontakt\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Then the distinction can be simplified as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Domain<\/strong> <code>meine-firma.ch<\/code><\/li>\n\n\n\n<li><strong>Hostname:<\/strong> <code>www.meine-firma.ch<\/code><\/li>\n\n\n\n<li><strong>URL:<\/strong> <code>https:\/\/www.meine-firma.ch\/kontakt\/<\/code><\/li>\n\n\n\n<li><strong>Website:<\/strong> the entire website, which includes the contact page among other things<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Another URL of the same website could be, for example:<\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/www.meine-firma.ch\/ueber-uns\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The domain remains the same, while the URL points to a different resource or page.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is the distinction important in technical problems?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If a website is unreachable, it does not automatically mean that the domain itself has a problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible causes may include, for example, DNS resolution, the web server, hosting, an SSL certificate, or the website application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Similarly, the domain can point correctly to the website while emails do not work due to a different DNS or mail server configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When troubleshooting, it is therefore helpful to describe as precisely as possible which service is affected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of simply saying \u201eMy domain is not working,\u201c the information \u201eThe website is unreachable, but email is still working,\u201c for example, is technically much more informative.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Domain, website, and URL refer to different components of an internet presence.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Domain<\/strong> is the registered name like <code>meine-firma.ch<\/code>. DNS can be used to determine which systems and services are associated with this name.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Website<\/strong> is the actual internet presence with its pages, content, files, and, if applicable, database information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>URL<\/strong> describes the specific address of a resource, for example <code>https:\/\/www.meine-firma.ch\/kontakt\/<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hosting, domain registration, DNS, and website are closely related, but technically they are different components. This separation is particularly important for domain transfers, hosting changes, DNS updates, and troubleshooting.<\/p>","protected":false},"excerpt":{"rendered":"<p>Website, Domain und URL werden im Alltag h\u00e4ufig gleichbedeutend verwendet.
