The original gTLDs: historical generic top-level domains

Original gTLDs are the first generic top-level domains created when the domain name system launched in 1985, including .com, .net, .org, .edu, .gov, and .mil. A handful of additional extensions such as .info, .biz, and .name joined the list before 2012. These are considered "original" or "historical" gTLDs because they predate ICANN's major expansion of new generic TLDs that began in 2012. Today, original gTLDs sit alongside a much broader set of generic TLDs, but they remain the extensions most people recognize first.

Like all gTLDs, original extensions such as .com, .net, and .org are open to registration by anyone, anywhere, regardless of location. Country code top-level domains (ccTLDs), by contrast, are two-letter extensions tied to a specific country, such as .uk for the United Kingdom, .de for Germany, or .jp for Japan. ccTLDs are managed by designated national organizations and may require local residency or a business presence to register. Original gTLDs carry no such geographic restrictions, which is part of why they became the default choice for websites worldwide.

Generally, yes. Original gTLDs like .com, .net, and .org carry decades of recognition and are widely perceived as established and credible. Users are familiar with them, and that familiarity carries inherent trust. Newer gTLDs introduced after 2012, like .shop, .online, or .xyz, are still building recognition and can sometimes be associated with spam due to low registration costs. That said, trust ultimately depends on the quality of the website and brand behind the domain name, not just its extension's age.

The price of an original gTLD is primarily determined by the registry operator that manages the extension. Each historical gTLD has a designated registry responsible for maintaining the DNS infrastructure and processing every domain name registration for that extension. The registry sets a wholesale price that registrars must pay for each domain registered.

Several factors influence this pricing. ICANN charges fees to registry operators for each domain registration, which get passed on to consumers. Operating costs also play a role: maintaining reliable DNS servers, security measures, and technical infrastructure requires significant investment. Market demand matters too. Original gTLDs like .com command higher prices due to their long track record and perceived value.

The original gTLD list stayed nearly unchanged for over two decades, until ICANN opened an application process that let organizations apply to operate entirely new extensions. Approved applicants become the registry operator responsible for managing their extension. Starting in 2012, ICANN's expansion rounds introduced hundreds of new gTLDs, like .app, .blog, and .shop, alongside the historical set.

For any TLD, original or new, to function, it must be delegated in the root zone, the authoritative list of all valid top-level domains in the DNS hierarchy. This delegation, overseen by ICANN and IANA, legitimizes a registry operator's authority to sell domains under that extension.
