Root Nameserver
A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD). The root name servers are a critical part of the Internet infrastructure because they are the first step in resolving human-readable host names into IP addresses that are used in communication between Internet hosts. A combination of limits in the DNS and certain protocols, namely the practical size of unfragmented User Datagram Protocol (UDP) packets, resulted in a decision to limit the number of root servers to thirteen server addresses. The use of anycast addressing permits the actual number of root server instances to be much larger, and is 1,553 . Root domain The DNS is a hierarchical naming system for computers, services, or any resource participating in the Internet. The top of that hier ...

ICANN
The Internet Corporation for Assigned Names and Numbers (ICANN ) is an American multistakeholder group and nonprofit organization responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, ensuring the network's stable and secure operation. ICANN performs the actual technical maintenance work of the Central Internet Address pools and DNS root zone registries pursuant to the Internet Assigned Numbers Authority (IANA) function contract.

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 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] |

Secure Sockets Layer
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to provide security, including privacy (confidentiality), integrity, and authenticity through the use of cryptography, such as the use of certificates, between two or more communicating computer applications. It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS handshake protocols. The closely related Datagram Transport Layer Security (DTLS) is a communications protocol providing security to datagram-based applications. In technical writing you often you will see references to (D)TLS when it applies to both versions. TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reston, Virginia
Reston is a census-designated place in Fairfax County, Virginia and a principal city of the Washington metropolitan area. As of the 2020 U.S. Census, Reston's population was 63,226. Founded in 1964, Reston was influenced by the Garden City movement that emphasized planned, self-contained communities that intermingled green space, residential neighborhoods, and commercial development. The intent of Reston's founder, Robert E. Simon, was to build a town that would revolutionize post–World War II concepts of land use and residential/corporate development in suburban America. In 2018, Reston was ranked as the Best Place to Live in Virginia by ''Money'' magazine for its expanses of parks, lakes, golf courses, and bridle paths as well as the numerous shopping and dining opportunities in Reston Town Center.

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. 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 for transitional purposes toward th ...
