A domain name is a text-based label that identifies Internet^[3] resources such as computers and services. It serves as an indicator of ownership or control over a resource and provides an easily recognizable name for these resources. In structure, a domain name is made up of concatenated labels separated by dots, arranged in a descending hierarchy from right to left. Each label can contain 1 to 63 octets and the overall domain name should not exceed 253 ASCII characters. The Système de noms de domaine^[1] (DNS) translates these domain names into IP addresses, helping to distribute web traffic^[2] across different servers. Domain names are organized into a tree structure, with Top-Level Domains (TLDs) such as .com, .org, .net at the highest level. The Internet Corporation for Assigned Names and Numbers (ICANN) oversees the allocation of TLDs and accredits domain registrars. Domain names can also be internationalized, with many registries adopting the Internationalized domain name (IDNA) system approved by ICANN. The domain name industry is subject to cyber threats like spoofing, but measures are in place for protection.

Définitions des termes

1. ↑ Système de noms de domaine ( Domain Name System ) The Domain Name System (DNS) is a vital part of the internet's infrastructure. It works as a translator between human-friendly hostnames and numerical IP addresses. This system helps users access websites and online services swiftly and efficiently. The DNS has been in use since the ARPANET era, where it began as a simple mapping system. Over time, it has developed into a complex hierarchical structure that is crucial for cloud services and content delivery networks. The DNS uses protocols like UDP and TCP to provide reliable, secure, and private connections. It also holds various types of records, such as SOA, A, AAAA, MX, NS, PTR, and CNAME, which are traditionally stored in a zone file. These records are important for the operation of distributed Internet services. The DNS helps users get faster responses by assigning proximal servers. Its structure is reflective of administrative responsibility on the internet, with zones of autonomy assigned to managers for each subdomain.

2. ↑ web traffic. Web traffic, the main subject of this text, is an essential aspect of digital business. In simple terms, it refers to the number of people visiting a website. These visits, also known as 'hits,' provide valuable data about the website's popularity and performance. Analysis of this data, known as web analytics, helps businesses understand visitor behavior and optimize their online presence. Monitoring web traffic can also highlight potential issues, like traffic overload, which can slow or crash a website. Various tools and strategies, such as Search Engine Optimization (SEO) and online advertising, can increase web traffic. However, it's important to manage this growth carefully to ensure the website can handle increased activity and isn't overwhelmed. Additionally, limiting access to certain parts of the website or to certain users is another aspect of managing web traffic, which helps maintain security and performance.

Dans le cadre de la Internet, a nom de domaine est un 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 sites web, courriel 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 ou un Protocole Internet (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 Système de noms de domaine (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, eduet orget le country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users who wish to connect local area networks to the Internet, create other publicly accessible Internet resources or run websites. The registration of a second- or third-level domain name is usually administered by a domain name registrar who sell its services to the public.

A fully qualified domain name (FQDN) is a domain name that is completely specified with all labels in the hierarchy of the DNS, having no parts omitted. Traditionally a FQDN ends in a dot (.) to denote the top of the DNS tree. Labels in the Domain Name System are case-insensitive, and may therefore be written in any desired capitalization method, but most commonly domain names are written in lowercase in technical contexts.
