Generic top-level domain
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. The core group of generic top-level domains consists of the com, net, org, biz, and info domains.
.am
.am is the internet country code top-level domain (ccTLD) for Armenia. The Armenia Network Information Centre is managed by the Internet Society of Armenia and is headquartered in Yerevan. The registry for .am is operated by ISOC-AM, the local chapter of the Internet Society. Regulatory notes: Any person in the world can register a .am, .com.am, .net.am, .org.am domain for a fee. Each domain name is subject to review. Generally, each review takes about 2 or 3 working days.
.cd
.cd is the Internet country code top-level domain (ccTLD) for the Democratic Republic of the Congo. It was created in 1997 as a replacement for the .zr (Zaire) ccTLD, which was phased out and eventually deleted in 2001. Except for reserved names like .com.cd, .net.cd, .org.cd and others, any person in the world can register a .cd domain for a fee. The ccTLD is popular (and thus economically valuable) owing to it being an abbreviation for compact disc (other similar ccTLDs are .fm, .am, .tv, .dj, .mu, and .
.hk
.hk is the designated Internet country code top-level domain (ccTLD) for Hong Kong. It is administered by the Hong Kong Internet Registration Corporation (HKIRC), the only organization endorsed by the Hong Kong Government to undertake the administration of 'hk' domain names. Hong Kong Internet Registration Corporation (HKIRC) is a non-profit making, non-statutory, member-based corporation established in 2001. From its inception in 1990 until 2002, the domain was administered by the Joint University Computer Centre.
Top-level domain
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.
Verisign
Verisign Inc. is an American company based in Reston, Virginia, United States, that operates a diverse array of network infrastructure, including two of the Internet's thirteen root nameservers, the authoritative registry for the , , and generic top-level domains and the country-code top-level domains, and the back-end systems for the and sponsored top-level domains. In 2010, Verisign sold its authentication business unit – which included Secure Sockets Layer (SSL) certificate, public key infrastructure (PKI), Verisign Trust Seal, and Verisign Identity Protection (VIP) services – to Symantec for $1.
Domain Name System Security Extensions
The Domain Name System Security Extensions (DNSSEC) are a suite of extension specifications by the Internet Engineering Task Force (IETF) for securing data exchanged in the Domain Name System (DNS) in Internet Protocol (IP) networks. The protocol provides cryptographic authentication of data, authenticated denial of existence, and data integrity, but not availability or confidentiality. The original design of the Domain Name System did not include any security features. It was conceived only as a scalable distributed system.
.coop
.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. The TLD was proposed by the National Cooperative Business Association (NCBA) as a response to the announcement by the Internet Corporation for Assigned Names and Numbers (ICANN) in late 2000 of a phased release of seven new generic top-level domains in an expansion of the Internet domain name space.
Domain name
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.
.edu
The domain name .edu is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. The domain was implemented in 1985 to create a domain name hierarchy for organizations with a focus on education. At the time, it was open for registration for entities from any region. Since 2001, new registrants for second-level domain names have been required to be United States–affiliated institutions of higher education. List of the oldest currently registered .
