.aero (derived from aeronautics) is a sponsored top-level domain (sTLD) used in the Domain Name System of the Internet. It is the first sponsored top-level domain based on a single industrial theme. The .aero
domain is reserved for companies, organizations, associations, government agencies, and individuals in aerospace-related fields. It was created in 2002 and is operated by SITA. SITA created and operates the Dot Aero Council.
Two-letter codes under .aero
are reserved for airlines according to the IATA Airline Designators. While three-letter codes were initially reserved for airports (IATA airport code), they were released for registration by the larger aviation and aerospace community on December 1, 2008. [1]
The aero
top-level domain was initially approved in 2001 for a 5-year term expiring December 17, 2006 as part of a proof-of-concept of new top-level domains. The agreement was extended in October 2006 for a six-month term until June 17, 2007, [2] and continued to be renewed on a June–December six-month cycle through June 17, 2009. In 2009, SITA and ICANN completed a new 10-year sponsorship agreement for the operation of .aero

The Internet Corporation for Assigned Names and Numbers is a global multistakeholder group and nonprofit organization headquartered in the United States responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, ensuring the Internet's stable and secure operation. ICANN performs the actual technical maintenance work of the Central Internet Address pools and DNS root zone registries pursuant to the Internet Assigned Numbers Authority (IANA) function contract. The contract regarding the IANA stewardship functions between ICANN and the National Telecommunications and Information Administration (NTIA) of the United States Department of Commerce ended on October 1, 2016, formally transitioning the functions to the global multistakeholder community.
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last non-empty label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is .com. Responsibility for management of most top-level domains is delegated to specific organizations by the ICANN, an Internet multi-stakeholder community, which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone.
In the Internet, a domain name is a string that identifies a realm of administrative autonomy, authority or control. Domain names are often used to identify services provided through the Internet, such as websites, email services and more. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer.
The domain com is a top-level domain (TLD) in the Domain Name System (DNS) of the Internet. Created in the first group of Internet domains at the beginning of 1985, its name is derived from the word commercial, indicating its original intended purpose for subdomains registered by commercial organizations. Later, the domain opened for general purposes.
.info is a generic top-level domain (gTLD) in the Domain Name System (DNS) of the Internet. The name is derived from information, although registration requirements do not prescribe any particular purpose.
.coop is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. It is intended for the use of cooperatives, their wholly owned subsidiaries, and other organizations that exist to promote or support cooperatives.
A domain name registrar is a company that manages the reservation of Internet domain names. A domain name registrar must be accredited by a generic top-level domain (gTLD) registry or a country code top-level domain (ccTLD) registry. A registrar operates in accordance with the guidelines of the designated domain name registries.
.xxx is a sponsored top-level domain (sTLD) intended as a voluntary option for pornographic sites on the Internet. The sponsoring organization is the International Foundation for Online Responsibility (IFFOR). The registry is operated by ICM Registry LLC. The ICANN Board voted to approve the sTLD on 18 March 2011. It went into operation on 15 April 2011.
.museum is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet used exclusively by museums, museum associations, and individual members of the museum profession, as these groups are defined by the International Council of Museums (ICOM).
Generic top-level domains (gTLDs) are 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. A top-level domain is the last level of every fully qualified domain name. They are called generic for historical reasons; initially, they were contrasted with country-specific TLDs in RFC 920.
A sponsored top-level domain (sTLD) 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, alongside country-code top-level domains (ccTLD) and generic top-level domains (gTLD).
.ky is the Internet country code top-level domain (ccTLD) for the Cayman Islands. The code was chosen as other possible options had already been allocated. Registration was limited to residents and registered companies in the Cayman Islands with a local address, but this restriction was removed in September 2015. The Cayman Islands also has the international three-letter code CYM and has won a bid to be awarded the .cym domain in a future expansion of the top-level domain space.
.so is the internet country code top-level domain (ccTLD) for Somalia. After a long absence, the .so domain was officially relaunched on November 1, 2010, by .SO Registry, which is regulated by the nation's Ministry of Posts and Telecommunications. It was launched through various accredited registrars around the world.
.web is a proposed top-level domain (TLD) that was created and assigned by an auction process to several bidding companies. It was awarded to Nu Dot Co LLC, which is primarily funded by Verisign.
.rs is the Internet country code top-level domain (ccTLD) for Serbia. The domain name registry that operates it is the Serbian National Internet Domain Registry (RNIDS). The letters rs stand for Republika Srbija/Република Србија.
Prior to the globalization of the Internet, its assignment of domain names was administered within the research and academic communities through the Internet Assigned Numbers Authority (IANA). As the Internet grew to a global service, in the 1990s, there was increasing pressure to add more "generic" top-level domain names, beyond the initial set, such as .com and .org and the two-letter country codes. Extensive debate within the Internet operational community did not resolve this. Finally, a composite group was formed, to create a proposal for the enhancement. The International Ad Hoc Committee (IAHC) was composed of members named by a variety of Internet and International sponsoring organizations.
.africa is the officially designated top-level domain (TLD) for the African and Pan African communities and users wherever they reside. It is a sponsored generic top-level domain (gTLD) operated by the Registry Africa. The .africa namespace is open to individuals, businesses and organizations around the world. The .africa domains are intended to showcase their brand and commitment to the African continent, establishing a home for Africa-specific products and services, expanding a brand's regional influence and acquiring online real-estate.
.music is a community-based top-level domain name (TLD) operated for the benefit of the global music community. It was one of the most highly contested new gTLDs, with eight applicants in contention.
An internationalized country code top-level domain is a top-level domain in the Domain Name System (DNS) of the Internet. IDN ccTLDs are specially encoded domain names that are displayed in an end user application, such as a web browser, in their language-native script or alphabet, such as the Arabic alphabet, or a non-alphabetic writing system, such as Chinese characters. IDN ccTLDs are an application of the internationalized domain name system to top-level Internet domains assigned to countries, or independent geographic regions.
.wiki is a top-level domain name. Its purpose is to denote websites that are wikis. It was proposed in ICANN's New generic top-level domain (gTLD) Program, and became available to the general public on May 26, 2014. Top Level Design is the domain name registry for the string.
