Pseudo-top-level Domain
A pseudo-top-level domain is a label or name for a computer network that is not participating in the world-wide official Domain Name System and may not even participate in the Internet, but may use a similar domain name hierarchy. Historically the best known large networks in this group were .bitnet, .csnet, .oz, and .uucp, for which many Internet mail forwarders provided connectivity. In addition, newer networks like .exit, .i2p, may be included. (Newest draft of the proposal expired on July 28, 2015 without becoming a standard.) Some domains such as .onion later become officially recognised. Although these networks or domain names have no official status, some are generally regarded as having been unofficially grandfathered, and are unlikely ever to be allocated as top-level domains. Pseudo-top-level domains are also sometimes used for fictitious domain names in video games and other media in order to prevent practical jokers and curious people from either bothering websites and o ...

Domain Name System
The Domain Name System (DNS) is a hierarchical and distributed naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks. It associates various information with domain names assigned to each of the associated entities. Most prominently, it translates readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. The Domain Name System has been an essential component of the functionality of the Internet since 1985. The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over sub-domains of their allocated name space to other name servers. This mechanism provides distributed and fault tolerance, fault-tolerant service and was designed to avoid a single ...

Bitnet
BITNET was a co-operative U.S. university computer network founded in 1981 by Ira Fuchs at the City University of New York (CUNY) and Greydon Freeman at Yale University. The first network link was between CUNY and Yale. The name BITNET originally meant "Because It's There Network", but it eventually came to mean "Because It's Time Network". A college or university wishing to join BITNET was required to lease a data circuit ( phone line) from a site to an existing BITNET node, buy modems for each end of the data circuit, sending one to the connecting point site, and allow other institutions to connect to its site free of charge. Technical details Bitnet, with Remote Spooling Communications Subsystem (RSCS) and the Network Job Entry (NJE) network protocol, was used for the huge IBM internal network known as VNET. BITNET links originally ran at 9600 bit/s. The BITNET protocols were eventually ported to non-IBM mainframe operating systems, and became particularly widely implemen ...

Csnet
The Computer Science Network (CSNET) was a computer network that began operation in 1981 in the United States. Its purpose was to extend networking benefits, for computer science departments at academic and research institutions that could not be directly connected to ARPANET, due to funding or authorization limitations. It played a significant role in spreading awareness of, and access to, national networking and was a major milestone on the path to development of the global Internet. CSNET was funded by the National Science Foundation for an initial three-year period from 1981 to 1984. History Lawrence Landweber at the University of Wisconsin–Madison prepared the original CSNET proposal, on behalf of a consortium of universities (Georgia Institute of Technology, Georgia Tech, University of Minnesota, University of New Mexico, University of Oklahoma, Purdue University, University of California, Berkeley, University of Utah, University of Virginia, University of Washington, Univ ...

Uucp
UUCP is an acronym of Unix-to-Unix Copy. The term generally refers to a suite of computer programs and protocols allowing remote execution of commands and transfer of files, email and netnews between computers. A command named is one of the programs in the suite; it provides a user interface for requesting file copy operations. The UUCP suite also includes (user interface for remote command execution), (the communication program that performs the file transfers), (reports statistics on recent activity), (execute commands sent from remote machines), and (reports the UUCP name of the local system). Some versions of the suite include / (convert 8-bit binary files to 7-bit text format and vice versa). Although UUCP was originally developed on Unix in the 1970s and 1980s, and is most closely associated with Unix-like systems, UUCP implementations exist for several non-Unix-like operating systems, including DOS, OS/2, OpenVMS (for VAX hardware only), AmigaOS, classic Mac OS, an ...

Onion
An onion (''Allium cepa'' L., from Latin ''cepa'' meaning "onion"), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus ''Allium''. The shallot is a botanical variety of the onion which was classified as a separate species until 2010. Its close relatives include garlic, scallion, leek, and chive. This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion (''Allium fistulosum''), the tree onion (''A.'' × ''proliferum''), and the Canada onion (''Allium canadense''). The name ''wild onion'' is applied to a number of ''Allium'' species, but ''A. cepa'' is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested in its f ...

Grandfather Clause
A grandfather clause, also known as grandfather policy, grandfathering, or grandfathered in, is a provision in which an old rule continues to apply to some existing situations while a new rule will apply to all future cases. Those exempt from the new rule are said to have grandfather rights or acquired rights, or to have been grandfathered in. Frequently, the exemption is limited, as it may extend for a set time, or it may be lost under certain circumstances; for example, a grandfathered power plant might be exempt from new, more restrictive pollution laws, but the exception may be revoked and the new rules would apply if the plant were expanded. Often, such a provision is used as a compromise or out of practicality, to allow new rules to be enacted without upsetting a well-established logistical or political situation. This extends the idea of a rule not being retroactively applied. Origin Southern United States The term originated in late nineteenth-century legislation and ...

Cybersquatting
Cybersquatting (also known as domain squatting) is the practice of registering, trafficking in, or using an Internet domain name, with a bad faith intent to profit from the goodwill of a trademark belonging to someone else. The term is derived from " squatting", which is the act of occupying an abandoned or unoccupied space or building that the squatter does not own, rent, or otherwise have permission to use. Terminology In popular terms, “cybersquatting” is the term most frequently used to describe the deliberate, bad faith abusive registration of a domain name in violation of trademark rights. However, precisely because of its popular currency, the term has different meanings to different people. Some people, for example, include “warehousing,” or the practice of registering a collection of domain names corresponding to trademarks with the intention of selling the registrations to the owners of the trademarks, within the notion of cybersquatting, while others distingui ...

Alternative DNS Root
The Internet uses the Domain Name System (DNS) to associate numeric computer IP addresses with human-readable names. The top level of the domain name hierarchy, the DNS root, contains the top-level domains that appear as the suffixes of all Internet domain names. The most widely used (and first) DNS root is administered by the Internet Corporation for Assigned Names and Numbers (ICANN). In addition, several organizations operate alternative DNS roots, often referred to as alt roots. These alternative domain name systems operate their own root name servers and commonly administer their own specific name spaces consisting of custom top-level domains. The Internet Architecture Board (IAB) has spoken out strongly against alternative roots in . Overview The DNS root zone consists of pointers to the authoritative domain name servers for all top-level domains (TLDs). The root zone is hosted on a collection of root servers operated by several organizations around the world that all use a ...
