Domain extension questions

How many domain extensions are there?

There are 1,436 active domain extensions in the IANA root zone: 1,126 generic (gTLDs), 309 country-code (ccTLDs), and the infrastructure domain .arpa. Of these, 151 are internationalized extensions written in local scripts or with accented letters.

Which domain extension is the largest?

In our data, .com is the largest extension, with 168,904,811 domains. The table above shows the rest of the top 10.

Are a domain extension, a TLD, and a domain zone the same thing?

In everyday use, yes. They all refer to the part of a domain name after the last dot, such as .com in example.com. TLD (top-level domain) is the technical term, and a domain zone is the part of the DNS that a registry manages. Endings such as .co.uk aren't listed separately because they sit under .uk.

What is the difference between a gTLD and a ccTLD?

A gTLD is a generic extension that isn't tied to a country, such as .com, .org, or .shop. A ccTLD is assigned to a country or territory and usually matches its two-letter code, such as .de for Germany. See every ccTLD in our list of domain zones by country.

What does xn-- mean in a domain extension?

It marks the ASCII form of an internationalized extension, known as Punycode, which is how DNS stores names written in other scripts. For example, .рф is xn--p1ai in DNS. Because all of these start with xn--, we list them in the IDN section rather than under X.

Can anyone register a domain in any extension?

No. Many extensions, such as .com and .xyz, are open to the public. Others are reserved for one company, such as .google, or have eligibility rules, such as .bank. Some country-code extensions also require a local presence, such as .ca for Canada.

Where does this list come from?

It comes from the IANA Root Zone Database, the official list of top-level domains. We only list extensions that are currently assigned. You can follow additions and removals on our IANA zone changes page.

How can I download all the domains in an extension?

Open an extension to preview its domains and download options, browse all domain lists, or get every zone in one ZIP file. Full downloads require a paid plan.

Need the domains, not just the extensions?
