.gb
.gb is a reserved Internet country code top-level domain (ccTLD) for the United Kingdom. The domain was introduced with RFC 920 in October 1984 that set out the creation of ccTLD generally using country codes derived from the corresponding two-letter code in the ISO 3166-1 list. However, the .uk domain had been created separately a few months before the compilation of this list. Consequently, .gb was never widely used. It is no longer possible to register under this domain. .gb was used for a number of years, mainly by British government organisations and commercial e-mail services using X.400-based e-mail infrastructure. This simplified translating between DNS domains and X.400 addresses, which used "GB" as a country code. With the demise of X.400 e-mail and IANA's general aim of one TLD per country, use of .gb declined; the domain remains in existence, but it is not currently open to new domain registrations. , dra.hmg.gb still exists, with at least three subdomains re ...

Country Code Top-level Domains
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. In 2018, the Internet Assigned Numbers Authority (IANA) began implementing internationalized country code top-level domains, consisting of language-native characters when displayed in an end-user application. Creation and delegation of ccTLDs is described in RFC 1591, corresponding to ISO 3166-1 alpha-2 country codes. While gTLDs have to obey international regulations, ccTLDs are subjected to requirements that are determined by each country’s domain name regulation corporation. With over 150 million domain name registrations today or as of 2022, ccTLDs make up about 40% of the total domain name industry. Country code extension applications began in 1985. The registered country code extensions in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Internet Properties Established In 1985
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource sharing. Th ...

Defence Science And Technology Laboratory
The Defence Science and Technology Laboratory (Dstl) is an executive agency of the Ministry of Defence of the United Kingdom. Its stated purpose is "to maximise the impact of science and technology for the defence and security of the UK". The agency is headed by Paul Hollinshead as its Chief Executive, with the board being chaired by Adrian Belton. Ministerial responsibility lies with the Minister for Defence Procurement. History Dstl was formed from the July 2001 split of the Defence Evaluation and Research Agency (DERA). Dstl was established to carry out and retain the science and technology work that is best done within government, while work that could be done by industry (forming the majority of DERA's activities) was transferred to Qinetiq, a government-owned company that was later floated on the stock exchange. Dstl absorbed the Home Office's Centre for Applied Science and Technology (CAST) in April 2018, taking on CAST's role to apply science and technology to support ...
