Top-Level Domain (TLD)

The Top Level Domain name (TLD) is the last or right-most fragment of the domain name. The parts of the domain name are separated with dots and form their own hierarchy in the Domain Name System (DNS). There is a Top-Leveл Domain list where you can see all available TLDs: they are about 300 predefined TLDs that serve different purposes. The Second Level Domains are basically website names and brands. You can come up with any Second Level Domain (SLD) name for a certain TLD for your site and you can register it (unless someone else already had registered that domain). For example in www.zettahost.comthere are three domain name levels: the first, Top Level Domain is the .compart, the Second Level Domain is .zettahost – the website name and the Third Level Domain is the www part. The TLDs are managed by the Internet Corporation for Assigned Names and Numbers (ICANN).

 

Types Of Top Level Domains

The domain TLDs can be divided into a few categories. There are country-code Top-Level Domain names or ccTLDs, which consist of two letters and have been created to serve more than 200 countries and regions (ccTLDs are .de.us.fr, etc.). Most of the Top Level Domains with three or more letters are known as generic Top Level Domains or gTLDs. The generic TLDs themselves can be divided into subcategories: of sponsored gTLDs and unsponsored gTLDs. Generic Top Level Domains are .com.net.edu.org.info and more. Some TLDs can be freely registered by anyone, but others pose certain limitations because they could be used only for certain purposes or in certain regions (for example, at the moment only U.S.-based universities and educational institutions accredited by the U.S. Department of Education may acquire the .edu domain). There are also internationalized country code Top Level Domains (IDN ccTLD) that are domain names specifically encoded to appear in the non-Latin alphabet in browsers (Arabic, Cyrillic, Chinese alphabet).
