There are also specialized top-level domains such as .edu for educational institutions and .gov for government agencies that define the institutional nature of the subject. Since 2014, with the opening by ICANN (Internet Corporation for Assigned Names and Numbers), new TLDs have been introduced, expanding the possibility of registering domains with more specific extensions.
Let's think for example of the extensions .online, .cloud, .pizza or the asia phone number extensions suitable for an e-commerce : they are all recent and allow you to better define the brand identity and make the core business of the activity immediately clear.
Second-level domains represent the main and customizable identifying element within the hierarchical structure. Positioned before the extension, these domains allow organizations, companies and professionals to create a unique and recognizable digital identity.
In fact, the choice of the second-level domain becomes strategic for online communication, influencing branding aspects. It can refer to the name of the company, the brand, the service offered or represent a distinctive element that facilitates the immediate identification of the entity or online activity.
