TLDs Listed Alphabetically

A top-level domain (TLD) is the last part of the domain name, the suffix that comes after the final dot in a domain name. In example.com, .com is the TLD and example is the label at the second level. Every TLD sits in the root zone of the domain name system (DNS), the name system of the internet that maps names to the correct IP address so browsers reach the right IP addresses. The Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), maintains the DNS root zone and delegates each TLD to a registry that runs its TLD server. In practice, every internet domain you visit ends in one of these TLDs. If you are new to this, start with what is a domain for a website and how the domain name system fits together.

IANA lists every internet top-level domain and sorts them into groups: generic top-level domains (gTLDs) like .com, country-code top-level domains (ccTLDs) like .uk, and sponsored top-level domains (sTLDs) intended for use by a defined community. There is one infrastructure top-level domain, or infrastructure TLD: the ARPA domain .arpa (the address and routing parameter area). A few are reserved, such as the int TLD .int for treaty bodies, .gov for government agencies, and .mil, run by the United States Department of Defense (the U.S. military). The Internet Engineering Task Force (IETF) also reserves a small set of special-use domain names, including the test top-level domains such as .test. Together they make up the full TLD list you can browse here.

A country code top-level domain (ccTLD) is a two-letter TLD assigned to a specific country or territory, such as .uk (as in co.uk), .de, or .jp. The two-letter codes follow the ISO country-code standard, and IANA delegates the responsibility for each one to a national registry. Some country code TLDs are marketed worldwide as an alternative TLD, with domains like .io, .co, and .me popular well beyond their home region, though most cctlds still point to a specific country. There are also internationalized country code top-level domains that use non-Latin scripts, a type of internationalized domain name (IDN). See every option under country tlds, or read what is a cctld for a deeper look at country code TLDs.

A generic top-level domain (gTLD) is a TLD that is not tied to any country. The original generic TLDs were a small set. These domains were created in the 1980s and included .com, .net, and .org, which grew into the main TLD choice for most of the web. These early domains established the naming conventions we still use, and over time such domains became the default for new businesses. Since 2013, ICANN's new gTLDs program has added hundreds of new TLDs, so today there is a huge variety of TLDs and far more domains to choose from than ever before. These newer TLDs range from .app and .dev to .shop and .blog. Compare generic TLDs or explore the new generic top-level domains from recent application rounds.

Start with a short, memorable name, then match it to the right domain extension. Check availability across a variety of TLDs at once so you can compare options, and weigh each TLD against your audience. The .com is still the main TLD most brands reach for, but a niche extension can say exactly what you do. Your choice of TLD does not directly change SEO performance, since search engines judge a new domain on content and links, not the top level domain you pick. There is no single best top level domain. The best TLD is the one that fits your brand, so keep your chosen domain easy to say and spell. Browse interesting domain extensions for ideas, then register a domain name through our domain name search box to lock in your new domain name and find the perfect domain.

When you register a domain you are paying a registrar for the right to use it for a set term, so watch a few prices. Registration is the first-year fee, the domain renewal is what you pay each year after that, and a domain transfer fee applies when you move the domain to another domain registrar. Different TLDs price registration and renewal differently, and some names are premium domains that the registry lists higher. Domain registration is an annual arrangement, not a one-time purchase. A domain also carries resale value: sought-after names trade at auction or through domain brokers, and a strong one can sell for far more than it cost to register. If you want to buy or sell domain names, see how domain value is set, then compare domain prices across registrars before you commit. Your registrar handles renewals and day-to-day domain management once the name is yours.

Yes. Many new gTLDs are industry-specific, grouped around industry and community theme concepts so you can match a domain to your field. Most are open, so anyone can register one, while a few are intended for use by a defined group. The table below maps common industries to example TLDs. Browse them all under TLD categories.

The .school and .education extensions, for example, suit educational institutions, while .gov stays reserved for government agencies.
