Network Information Centre
A domain name registry is a database of all domain names and the associated registrant information in the top level domains of the Domain Name System (DNS) of the Internet that enables third party entities to request administrative control of a domain name. Most registries operate on the top-level and second-level of the DNS. A registry operator, sometimes called a network information center (NIC), maintains all administrative data of the domain and generates a zone file which contains the addresses of the nameservers for each domain. Each registry is an organization that manages the registration of domain names within the domains for which it is responsible, controls the policies of domain name allocation, and technically operates its domain. It may also fulfill the function of a domain name registrar, or may delegate that function to other entities. Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA), which manages the top of the ...

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. 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. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names are organized in subordinate levels ('' subdomains'') of the DNS root domain, which is nameless. The first-level set of domain names are the ''top-level domains'' (TLDs), including the ''generic top-level domains'' (gTLDs), such as the prominent domains com, info, net, edu, and org, and the ''country code t ...

Public Records
Public records are documents or pieces of information that are not considered confidential and generally pertain to the conduct of government. Depending on jurisdiction, examples of public records includes information pertaining to births, deaths, marriages, and documented transaction with government agencies. Attitudes and expectations about what information should be made public have been studied. History Since the earliest organised societies, with taxation, disputes, and so on, records of some sort have been needed. In ancient Babylon records were kept in cuneiform writing on clay tablets. In the Inca empire of South America, which did not have writing, records were kept via an elaborate form of knots in cords, quipu, whose meaning has been lost. In Western Europe in the Late Middle Ages public records included census records as well as records of birth, death, and marriage; an example is the 1086 ''Domesday Book'' of William the Conqueror. The details of royal marriage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Governance
Internet governance is the effort by governments, the private sector, civil society, and technical actors to develop and apply shared principles, norms, rules, and decision-making procedures that shape the evolution and use of the Internet. This article describes how the Internet was and is currently governed, some inherent controversies, and ongoing debates regarding how and why the Internet should or should not be governed in the future. (Internet governance should not be confused with e-governance, which refers to governmental use of technology in its governing duties.) Background No person, company, organization or government runs the Internet. It is a globally distributed network comprising many voluntarily interconnected autonomous networks. It operates without a central governing body with each constituent network setting and enforcing its own policies. Its governance is conducted by a decentralized and international multistakeholder network of interconnected autonomou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NIC Handle
A NIC handle (Network Information Centre handle) is a unique alphanumeric character sequence that represents an entry in the databases maintained by Network Information Centres. When a new domain name is registered with a domain name registrar, a NIC handle is assigned by the registrar to the particular set of information associated with that domain name (such as who registered it and a contact e-mail address). Once a domain name has been registered, its NIC handle can be used to search for that record in the database. The NIC handle was developed in 1982 by Ken Harrenstien and Vic White working at the early Network Information Center at SRI International. Modern use The NIC Handle system is no longer commonly used by domain name registries. It was previously possible to query WHOIS by NIC handle, and see all the domains registered by that NIC handle, but this service was discontinued (presumably due to spam Spam most often refers to: * Spam (food), a consumer brand product ...

List Of Internet Top-level Domains
This list of Internet top-level domains (TLD) contains top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet. A list of the top-level domains by the Internet Assigned Numbers Authority (IANA) is maintained at the Root Zone Database. IANA also oversees the approval process for new proposed top-level domains for ICANN. As of April 2021, the IANA Root Zone Database listed 1,502 top-level domains, including active, reserved, retired, and special-use domains.Root Zone Database Internet Assigned Numbers Authority. Retrieved April 1, 2021. By March 31, 2025, the number of actively delegated top-level domains had decreased to 1,264, reflecting removals, retirements, and changes in the root zone database.

Private Sub-domain Registry
A private sub-domain registry allocates domain names in a subset of the Domain Name System under a domain registered with an ICANN-accredited or ccTLD registry. Most of the private sub-domain registries operate based on an ISO 3166-1 name that is a subdomain of a higher-level domain. Some of these registries combine the domain registry and the domain registrar functions in the administration structure, while others distribute domains via third-party registrars. Operation Private registries operate at a technical level identical to official domain registries using the well-known principles of operation of the Domain Name System. In addition, the registries may also operate a WHOIS service to publish domain name information. History The idea for an independent global domain name registry stems from a series of conversations between one of CentralNic's original founders and the late Jon Postel, one of the founding fathers of the modern Internet. Postel suggested the use of ''.UK.COM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drop Registrar
A drop registrar is a domain name registrar who registers expiring Internet domain names immediately after they expire and are deleted by the domain name registry. A drop registrar will typically use automated software to send up to 250 simultaneous domain name registration requests in an attempt to register the domain name first. In recognition of the potential abuse of such a "domain land rush", ICANN and VeriSign Verisign, Inc. is an American company based in Reston, Virginia, 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 d ... limited the number of simultaneous requests to 250 since July 17, 2001.ICANAdvisory July 16, 2001 Drop registrars usually work for a domain back-order service, and receive a percentage of the final auction price.

Third-level Domain
In the Domain Name System (DNS) hierarchy, a subdomain is a domain that is a part of another (main) domain. For example, if a domain offered an online store as part of their website it might use the subdomain. Overview The Domain Name System (DNS) has a tree structure or hierarchy, which includes nodes on the tree being a domain name. A subdomain is a domain that is part of a larger domain. Each label may contain from 0 to 63 octets.RFC 1034, ''Domain Names - Concepts and Facilities'', P. Mockapetris (Nov 1987) The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.RFC 1035, ''Domain names--Implementation and specification'', P. Mockapetris (Nov 1987) Subdomains are defined by editing the DNS zone file pertaining to the parent domain. However, there is an ongoing debate over the use of the term "subdomain" when referring to names which map to the Address record A (host) and various other types of zone records which may map t ...

UDRP
The Uniform Domain-Name Dispute-Resolution Policy (UDRP) is a process established by the Internet Corporation for Assigned Names and Numbers (ICANN) for the resolution of disputes regarding the registration of internet domain names. The UDRP currently applies to all generic top level domains (.com, .net, .org, etc.), some country code top-level domains, and to all new generic top-level domains (.xyz, .online, .top, etc.). Historical background When ICANN was first set up, one of the core tasks assigned to it was "The Trademark Dilemma", the use of trade marks as domain names without the trademark owner's consent. By the late 1990s, such use was identified as problematic and likely to lead to consumers being misled. In the United Kingdom, the Court of Appeal described such domain names as "an instrument of fraud". One of the first steps was that Member States commissioned the United Nations World Intellectual Property Organization (WIPO) to produce a report on the tension between ...

ASCII
ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable character, printable and 33 control character, control characters a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers; for example, the first 128 code points of Unicode are the same as ASCII. ASCII encodes each code-point as a value from 0 to 127 storable as a seven-bit integer. Ninety-five code-points are printable, including digits ''0'' to ''9'', lowercase letters ''a'' to ''z'', uppercase letters ''A'' to ''Z'', and commonly used punctuation symbols. For example, the letter is represented as 105 (decimal). Also, ASCII specifies 33 non-printing control codes which originated with ; most of which are now obsolete. The control cha ...
