.na
.na is the Internet country code top-level domain (ccTLD) for Namibia corresponding to the two letter code from the ISO-3166 standard. The registry accredits both Namibian and foreign registrars. Registrars access the Registry and register domains using either a web-based GUI or the industry standard EPP protocol. The domain was established on 8 May 1991. The ccTLD manager is NA-NiC (Namibian Network Information Centre). The Namibian Parliament passed a Communications Act in 2009 containing various provisions regarding the ccTLD; however, as of the end of 2017, they had not yet entered into force. Registrations are available at both the second level or at the third level beneath various names that include some apparently redundant choices (e.g., both .co.na and .com.na for commercial entities). Domain registration costs Domain registration prices to the end-user are now set by registrars in competition with each other. Wholesale prices (the cost to the registrars) depend o ...

Namibia
Namibia, officially the Republic of Namibia, is a country on the west coast of Southern Africa. Its borders include the Atlantic Ocean to the west, Angola and Zambia to the north, Botswana to the east and South Africa to the south; in the northeast, approximating a quadripoint, Zimbabwe lies less than 200 metres (660 feet) away along the Zambezi, Zambezi River near Kazungula, Zambia. Namibia's capital and largest city is Windhoek. Namibia is the driest country in sub-Saharan Africa, and has been inhabited since prehistoric times by the Khoekhoe, Khoi, San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. From 1600 the Ovambo people#History, Ovambo formed kingdoms, such as Ondonga and Oukwanyama. In 1884, the German Empire established rule over most of the territory, forming a colony known as German South West Africa. Between 1904 and 1908, German troops waged a punitive ...

Top-level Domain
A top-level domain (TLD) is one of the domain name, 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 DNS root zone, 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 example.com, 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. History Originally, the top-level domain space was organized into three main groups: ''Countries'', ''Categories'', and ''Multiorganizations''. An additional ''temporary'' group consisted of only the initial DNS domain, .arpa, and was intended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Country Code Top-level Domain
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 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 that year in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensible Provisioning Protocol
The Extensible Provisioning Protocol (EPP) is a flexible protocol designed for allocating objects within registries over the Internet. The motivation for the creation of EPP was to create a robust and flexible protocol that could provide communication between domain name registries and domain name registrars. These transactions are required whenever a domain name is registered or renewed, thereby also preventing domain hijacking. Before its introduction, registries had no uniform approach, and many different proprietary interfaces existed. While its use for domain names was the initial driver, the protocol is designed to be usable for any kind of ordering and fulfillment system. EPP is based on XML - a structured, text-based format. The underlying network transport is not fixed, although the only currently specified method is over TCP. The protocol has been designed with the flexibility to allow it to use other transports such as BEEP, SMTP, SOAP or HTTPS. However only HTTPS h ...

Domain Name System Security Extensions
The Domain Name System Security Extensions (DNSSEC) is a suite of Extension Mechanisms for DNS, extension specifications by the Internet Engineering Task Force (IETF) for securing data exchanged in the Domain Name System (DNS hijacking, DNS) in Internet Protocol (IPv6, IP) Networks and States, networks. The protocol provides message authentication, cryptographic authentication of data, SOCKS, authenticated denial of existence, and data Information_security#Integrity, integrity, but not Information_security#Availability, availability or Information_security#Confidentiality, confidentiality. Overview The original design of the Domain Name System did not include any security features. It was conceived only as a scalable distributed system. The Domain Name System Security Extensions (DNSSEC) attempt to add security, while maintaining backward compatibility. of 2004 documents some of the known threats to the DNS, and their solutions in DNSSEC. DNSSEC was designed to protect applicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet
The Internet (or internet) is the Global network, global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a internetworking, network of networks that consists of Private network, private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, Wireless network, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and Web application, applications of the World Wide Web (WWW), email, electronic mail, internet telephony, streaming media and file sharing. The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Country Code
A country code is a short alphanumeric identification code for countries and dependent areas. Its primary use is in data processing and communications. Several identification systems have been developed. The term ''country code'' frequently refers to ISO 3166-1 alpha-2, as well as the telephone country code, which is embodied in the E.164 recommendation by the International Telecommunication Union (ITU). ISO 3166-1 The standard ISO 3166-1 defines short identification codes for most countries and dependent areas: *ISO 3166-1 alpha-2: two-letter code *ISO 3166-1 alpha-3: three-letter code * ISO 3166-1 numeric: three-digit code The two-letter codes are used as the basis for other codes and applications, for example, *for ISO 4217 currency codes *with deviations, for country code top-level domain names (ccTLDs) on the Internet: list of Internet TLDs. Other applications are defined in ISO 3166-1 alpha-2. ITU Telephone country codes Telephone country codes are telephone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO-3166
ISO 3166 is a standard published by the International Organization for Standardization (ISO) that defines codes for the names of countries, dependent territories, special areas of geographical interest, and their principal subdivisions (e.g., provinces or states). The official name of the standard is ''Codes for the representation of names of countries and their subdivisions''. Parts It consists of three parts: * ISO 3166-1, ''Codes for the representation of names of countries and their subdivisions – Part 1: Country code'', defines codes for the names of countries, dependent territories, and special areas of geographical interest. It defines three sets of country codes: ** ISO 3166-1 alpha-2 – two-letter country codes which are the most widely used of the three, and used most prominently for the Internet's country code top-level domains (with a few exceptions). ** ISO 3166-1 alpha-3 – three-letter country codes which allow a better visual association between the codes and t ...
