Definition - What does Top-Level Domain (TLD) mean?
Understanding the Top Level Domain or TLD"Top Level Internet Domain or TLD is a reference to the last letter after the dot in a domain name. For example, www.google.com has the top domain .com (or COM, since the domain name does not matter in capital or small). - Wikipedia"
3 of the Types of Top Level Domains TLD
1. Global Top-Level Domains (gTLD)Most consist of 3 letters or more. The extension entered in the gTLD type can be freely used by anyone, wherever it comes from except .mil (military) and .gov (Government). .mil and .gov Can be used only by the United States Government. So if you find a website that uses the domain. Miles already ascertained it belongs to the United States military. So is .gov.
When gTLD is dissected more deeply, there will be 2 subclassifications, ie sponsored top-level domains (sTLD) that are owned solely by organizations, organizations, associations, government agencies, and individuals in a particular area that are sponsored eg .aero, .coop and. The other subclassification is for extensions where there is no sponsorship relationship with gTLD. Commonly called (unsponsored top-level domains (uTLD), for example .biz, .info, .name and .pro.
2. Country code top-level domains (ccTLD)Extensions used for websites in certain countries. For example .id is an extension specifically reserved for websites that exist in the State of Indonesia. So it is not possible to find a website with .id domain with the main content of Mandarin.
