It&rsquo;s part of the domain name that makes an <a href=\"\/in\/tutorials\/what-is-ip-address\/\">IP address<\/a> easy to remember. For example, &ldquo;<strong>www<\/strong>&rdquo; is the hostname in <strong>www.hostinger.com<\/strong>, and &ldquo;<strong>en<\/strong>&rdquo; is the hostname in <strong>en.wikipedia.org<\/strong>.<\/li>\n\n\n\n<li><a href=\"\/in\/tutorials\/what-are-subdomains\/\">Subdomain<\/a> &#8210; located to the left of the main domain, it can show a specific subdivision or a service associated with a larger domain. For example, <strong>support.hostinger.com<\/strong> features &ldquo;<strong>support<\/strong>&rdquo; as the subdomain of <strong>hostinger.com<\/strong>. Note that not all domains have this element.<\/li>\n\n\n\n<li><strong>Domain name<\/strong> &#8210; consists of a second-level and a <a href=\"\/in\/tutorials\/what-is-tld\/\">top-level domain (TLD)<\/a>. With <strong>hostinger.com<\/strong>, &ldquo;<strong>hostinger<\/strong>&rdquo; represents the second-level domain, while &ldquo;<strong>.com<\/strong>&rdquo; is the TLD.<\/li>\n<\/ul><p class=\"wp-block-paragraph\">Fully qualified domain names need a final dot or a trailing period at the end, completing the domain&rsquo;s absolute path. For example, the absolute form of an FQDN would be written as &ldquo;<strong>www.hostinger.com.<\/strong>&rdquo;.<\/p><p class=\"wp-block-paragraph\">However, web browsers today usually assume the final dot, so users don&rsquo;t have to include it when entering a web address.<\/p><p class=\"wp-block-paragraph\">Keep in mind that the maximum length for any single label &#8210; hostname or segment of an FQDN &#8210; is <strong>63 bytes<\/strong>. The total length of an FQDN cannot exceed <strong>255 bytes<\/strong>.<\/p><h2 class=\"wp-block-heading\" id=\"h-what-is-a-partially-qualified-domain-name\">What Is a Partially Qualified Domain Name?<\/h2><p class=\"wp-block-paragraph\">A Partially Qualified Domain Name (PQDN) is a web address that doesn&rsquo;t include the full path specified by an FQDN. It might consist of only the hostname or a part of the domain structure, excluding the top-level domain (TLD).<\/p><p class=\"wp-block-paragraph\">Website developers often configure their sites&rsquo; <a href=\"\/in\/tutorials\/what-is-dns\/\">Domain Name System (DNS)<\/a> to redirect visitors to the same page whether they type in a PQDN or an FQDN.<\/p><p class=\"wp-block-paragraph\">For example, typing <strong>hostinger.com<\/strong> or <strong>www.hostinger.com<\/strong> in a web browser will redirect you to <strong>https:\/\/hostinger.com <\/strong>&#8210; the URL for our homepage. As PQDNs are shorter, they are easier for users to type and remember.<\/p><h2 class=\"wp-block-heading\" id=\"h-when-to-use-an-fqdn\">When to Use an FQDN<\/h2><p class=\"wp-block-paragraph\">FQDNs are used in various internet interactions since they are easier to remember than IP addresses. Here are several scenarios where using an FQDN is beneficial:<\/p><ul class=\"wp-block-list\">\n<li><strong>Getting an SSL certificate<\/strong> &#8210; a <a href=\"\/in\/tutorials\/what-is-ssl\/\">Secure Sockets Layer (SSL)<\/a> certificate, which secures the connection between a web server and a browser, uses an FQDN to verify the server&rsquo;s identity. Without an FQDN, the SSL protocol cannot operate properly.<\/li>\n\n\n\n<li><strong>Connecting to a remote host<\/strong> &#8210; when connecting to a remote host or virtual machine, using an FQDN helps DNS locate the server accurately. Relying solely on a hostname could lead to resolution failures if the local DNS can&rsquo;t expand it to a complete domain name.<\/li>\n\n\n\n<li><strong>Accessing specific domain services<\/strong> &#8210; FQDNs are crucial for network communications, such as <a href=\"\/in\/tutorials\/what-is-ftp\/\">File Transfer Protocol (FTP<\/a>) or email services. They ensure DNS directs traffic to the correct server.<\/li>\n\n\n\n<li><strong>Migrating to a new server<\/strong> &#8210; when migrating your services to another server, an&nbsp; FQDN lets you update only the DNS records for the new IP address. This way, you can minimize downtime due to IP address changes.<\/li>\n<\/ul><h2 class=\"wp-block-heading\" id=\"h-how-to-find-an-fqdn\">How to Find an FQDN<\/h2><p class=\"wp-block-paragraph\">Here&rsquo;s how you can find your own FQDN, depending on the operating system that you use.<\/p><p class=\"wp-block-paragraph\"><strong>Windows<\/strong><\/p><p class=\"wp-block-paragraph\">For users on the Windows operating system, follow the steps below to locate the FQDN in advanced system settings:<\/p><ol class=\"wp-block-list\">\n<li>Open the <strong>Start <\/strong>menu and open <strong>View your PC name<\/strong>.<\/li>\n\n\n\n<li>In the <strong>System <\/strong>tab, select <strong>Advanced system settings<\/strong>.<\/li>\n<\/ol><div
