Definition:<\/strong><\/p>\n A domain<\/strong>, or domain name, is a unique name within the Domain Name System hierarchy that identifies Internet resources and services through a human-readable address. A domain is not the website or the server that hosts it. It can be used for a website, email addresses and other services. The DNS<\/a> looks up the records associated with the name and directs each request to the appropriate resource.<\/p>\n\n When someone enters a domain name in a browser, a DNS resolver searches a distributed system of servers for the required information. The response may include an IP address or other records indicating where the requested service is located.<\/p>\n The same domain can have different records for different functions.<\/strong> A and AAAA records can direct web traffic to IPv4 or IPv6 addresses, while MX records specify which servers receive email. Registering a domain therefore does not mean that a website already exists: DNS must also be configured and the corresponding service must be available if a site is to be published.<\/p>\n Domain names have a hierarchical structure. Their labels are separated by dots and are interpreted from right to left. In The registrable domain generally consists of the chosen name and the top-level domain, such as The IANA Root Zone Database classifies TLDs according to their purpose and administration. Its main categories include:<\/p>\n Combinations such as To use an available name, a person or organisation registers it for a defined period through a registrar. The registry maintains the TLD database, while the registrar processes registrations, renewals and other changes for the registrant. Rules, terms and eligibility requirements depend on the extension.<\/p>\n ICANN coordinates policies and agreements concerning generic domains. The IANA functions maintain the root zone and TLD delegation data. The registrant should keep contact information current, protect access to the account and renew the domain on time<\/strong> to retain the right to use it.<\/p>\n A domain is one part of web infrastructure and should not be confused with the following concepts:<\/p>\n Definition: A domain, or domain name, is a unique name within the Domain Name System hierarchy that identifies Internet resources and services through a human-readable address. arimetrics.com is an example of a domain name.

Domain name structure<\/h2>\n
www.arimetrics.com<\/code>, the following levels can be distinguished:<\/p>\n\n
.com<\/code> in the example and is also known as the TLD.<\/li>\narimetrics<\/code>, the label registered under .com<\/code>.<\/li>\nwww<\/code> in the example. It is optional and can be replaced by labels such as blog<\/code>, shop<\/code> or mail<\/code>.<\/li>\n<\/ul>\narimetrics.com<\/code>, although registry rules vary. A subdomain<\/a> can organise services or sections under that domain without requiring a separate registration.<\/p>\nTypes of top-level domain<\/h2>\n
\n
.com<\/code>, .org<\/code>, .info<\/code> and .app<\/code>. Some have eligibility requirements, while others are open to general registration.<\/li>\n.es<\/code> or .fr<\/code>.<\/li>\n.aero<\/code> and .museum<\/code> have a sponsoring organisation and conditions linked to a particular community.<\/li>\n.arpa<\/code> is reserved for technical Internet infrastructure functions.<\/li>\n<\/ul>\ngov.uk<\/code> are not a mixed type of TLD.
