New Generic Top-Level Domains (New gTLDs)

On June 20, 2011, ICANN's board voted to end most restrictions on the generic top-level domain names (gTLDs) from the 22 available before.
Now companies and organizations are able to choose essentially arbitrary top-level Internet domains. The use of non-Latin characters (such as Cyrillic, Arabic, Chinese, etc.) is also allowed in gTLDs now.

Early Generic Top-Level Domains (gTLDs)

A generic top-level domain (gTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet.
It is visible to Internet users as the suffix at the end of a domain name.

Country Code Top-Level Domains (ccTLDs)

A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, a sovereign state, or a dependent territory.
All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.
