Domain Name

A domain name (Russian: доменное имя) is an identification label that defines a realm of administrative autonomy, authority, or control on the Internet, based on the Domain Name System (DNS). The Whois service queries the Whois databases managed by domain registrars and displays relevant information about the owner of a domain name. COM.RU domain (Russian: домен COM.RU) is a great solution for individuals and legal entities doing business in the Russian segment of the Internet. A .NAME domain (Russian: домен .NAME) can help ensure that the parts of your life you want to share find the right audience, from recent weekend trips to your resume's latest draft.

Domain name (for example, example.com or example.com.ru) are used in various networking contexts and application-specific naming and addressing purposes. They are organized in subordinate levels (subdomains) of the DNS root domain name, 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, net and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domains that are typically open for reservation by end-users that wish to connect local area networks to the Internet, run web sites, or create other publicly accessible Internet resources. The registration of these domain names is usually administered by domain name registrars who sell their services to the public. The domain auction process is a great way to sell domains. As described in RFC 2606, a number of domains such as "example.com, example.net, example.org, example.edu" for documentation purposes.

Individual Internet host computers use domains as host identifiers, or hostnames. Hostnames are the leaf labels in the domain name system usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites.

Domains are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the realm identifiers used in the Session Initiation Protocol (SIP), the DomainKeys used to verify DNS domains in e-mail systems, and in many other Uniform Resource Identifiers (URIs).

An important purpose of domains is to provide easily recognizable and memorizable names to numerically addressed Internet resources. This abstraction allows any resource (e.g., website) to be moved to a different physical location in the address topology of the network, globally or locally in an intranet. Such a move usually requires changing the IP address of a resource and the corresponding translation of this IP address to and from its domain name. An often used analogy to explain the DNS is that it serves as the “phone book” for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.example.com.ru translates to 90.156.201.108. Another example, www.example.com translates to 192.0.32.10. Domain name example.com resolve to a server managed by Internet Corporation for Assigned Names and Numbers (ICANN).
