Domains: Register A Domain
A domain name is a unique name that identifies
an internet resource such as a website. It is an identification string
that defines a realm of administrative autonomy, authority or control on
the Internet. Domain names are formed by the rules Domain Name System
(DNS). Any name registered in the DNS is a domain name. The functional
description of domain names is presented in the Domain Name System
article. Broader usage and industry aspects are captured here.
names are used in various networking contexts and 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 via the Internet. In 2014,
the number of active domains reached 271 million.
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, edu, 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 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 web sites. The registration of
these domain names is usually administered by domain name registrars who
sell their services to the public.
A fully qualified domain name
(FQDN) is a domain name that is completely specified in the hierarchy
of the DNS, having no parts omitted.
Domain names are usually written in lowercase, although labels in the Domain Name System are case-insensitive.
