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. As of 2017, 330.6 million domain names had been registered. 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.
This article concerns the systems of telecommunication in Austria. Austria has a highly developed and efficient telephone network, and has a number of radio and television broadcast stations.
.uk is the Internet country code top-level domain (ccTLD) for the United Kingdom. It was first registered in July 1985, seven months after the original generic top-level domains such as .com and the first country code after .us.
A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.
.ag is the Internet country code top-level domain (ccTLD) for Antigua and Barbuda.
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.
.il is the Internet country code top-level domain (ccTLD) of Israel, administered by the Israel Internet Association and managed by NIC - ISRAEL, which hosts the DNS root server and manages the Israeli Internet Exchange, that supports IPv4 and IPv6.
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).
.st is the Internet country code top-level domain (ccTLD) for São Tomé and Príncipe. The code is marketed worldwide as an abbreviation for various entities.
In the Domain Name System (DNS) hierarchy, a second-level domain is a domain that is directly below a top-level domain (TLD). For example, in example.com, example is the second-level domain of the .com TLD.
A domain hack is a domain name that suggests a word, phrase, or name when concatenating two or more adjacent levels of that domain. For example, bir.ds and examp.le, using the fictitious country-code domains .ds and .le, suggest the words birds and example respectively. In this context, the word hack denotes a clever trick, not an exploit or break-in.
The Domain Name System of the Internet consists of a set of top-level domains that constitute the root domain of the hierarchical name space and database. In the growth of the Internet, it became desirable to expand the initial set of six generic top-level domains in 1984. As a result, new top-level domain names have been proposed for implementation by ICANN. Such proposals included a variety of models ranging from adoption of policies for unrestricted gTLDs that could be registered by anyone for any purpose, to chartered gTLDs for specialized uses by specialized organizations. In October 2000, ICANN published a list of proposals for top-level domain strings it had received.
A geographic top-level domain is any of an unofficial group of top-level domains in the Domain Name System of the Internet using the name of or invoking an association with a geographical, geopolitical, ethnic, linguistic or cultural community. The IANA does not recognize these domains as their own group within the Root Zone Database, rather classifying them as generic top-level domains.
The Tagblatt-Pokal was the first football competition in Austria played in a league format. It was founded by the Neue Wiener Tagblatt, and was restricted to clubs in Vienna. Nevertheless, and despite the existence of the Challenge Cup, which was open to all football clubs in Austria-Hungary, it is regarded as a forerunner of the Austrian football championship. The trophy was awarded permanently to Wiener AC in 1903 after they had won it three times.
.at is the Internet country code top-level domain (ccTLD) for Austria. It is administered by nic.at.
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.
.design is a generic top-level domain name in the Domain Name System of the Internet. It was proposed in ICANN's new generic top-level domain (gTLD) program, and became available to the general public on May 12, 2015. Top Level Design was the domain name registry for the string until April 2021, when it was transferred to GoDaddy Registry.
.google is a brand top-level domain (TLD) used in the Domain Name System (DNS) of the Internet. Created in 2014, it is operated by Alphabet Inc., Google's parent company. It is notable as one of the first gTLDs associated with a specific brand. The company's first usage of the TLD was with com.google, an April Fools' Day joke website that hosted a horizontally mirrored version of Google Search. The domain currently hosts multiple Alphabet Inc. products and services, and plans exist to move other Alphabet properties to .google as well.
