title: Domain name text: Domain name A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. 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 used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated title: Domain Name System text: Authority over the new zone is said to be "delegated" to a designated name server. The parent zone ceases to be authoritative for the new zone. The definitive descriptions of the rules for forming domain names appear in RFC 1035, RFC 1123, and RFC 2181. A domain name consists of one or more parts, technically called "labels", that are conventionally concatenated, and delimited by dots, such as example.com. The right-most label conveys the top-level domain; for example, the domain name www.example.com belongs to the top-level domain "com". The hierarchy of domains descends from right to left; each label to the title: Domain name text: of registering a domain name and maintaining authority over the new name space created, registrars use several key pieces of information connected with a domain: A domain name consists of one or more labels, each of which is formed from the set of ASCII letters, digits, and hyphens (a-z, A-Z, 0-9, -), but not starting or ending with a hyphen. The labels are case-insensitive; for example, 'label' is equivalent to 'Label' or 'LABEL'. In the textual representation of a domain name, the labels are separated by a full stop (period). Domain names are often seen in analogy to real estate title: Domain name text: in the tree holds information associated with the domain name. The tree sub-divides into "zones" beginning at the DNS root zone. A domain name consists of one or more parts, technically called "labels", that are conventionally concatenated, and delimited by dots, such as "example.com". The top-level domains (TLDs) such as com, net and org are the highest level of domain names of the Internet. Top-level domains form the DNS root zone of the hierarchical Domain Name System. Every domain name ends with a top-level domain label. When the Domain Name System was devised in the 1980s, the domain name space title: Domain name registry text: Domain name registry 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 allow 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
