An example domain name is an FQDN – fully qualified domain names:

A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or host, on the internet. The FQDN consists of two parts: the hostname and the domain name or example, “” This is an FQDN since it contains a hostname (“www”) and a domain name (“”), followed by a trailing period. The name “” is not fully qualified because it does not include a hostname or end with a period.

Technically, a fully-qualified name includes a trailing period, which indicates the top of the name. Since a hostname can include multiple subdomains, like “,” it’s more reliable to process an FQDN backwards, beginning with the TLD and ending with the hostname. Ironically, the amount is the start line when a computer processes an FQDN.

While the trailing dot is an element of a fully-qualified name, in most cases, it’s implied. as an example, you do not must enter the amount when typing during a web address within the address bar of your application program or when entering the mail server in your email client. In other places, like a DNS zone file, it’s important to incorporate the trailing period for every FQDN.

NOTE: a website name that features the domain, TLD, and period, but no hostname is named a partially-qualified name, or PQDN.


While the term “domain” is usually used synonymously with “domain name,” it also includes a definition specific to local networks.

A domain contains a bunch of computers that may be accessed and administered with a standard set of rules. as an example, a corporation may require all local computers to be networked within the identical domain so each computer may be seen from other computers within the domain or located from a central server. putting in a website can also block outside traffic from accessing computers within the network, which adds an additional level of security.

While domains is setup employing a sort of networking software, including applications from Novell and Oracle, Windows users are possibly acquainted with Windows Network Domains. This networking option is constructed into Windows and allows users to form or join a website. The domain may or might not be password-protected. Once connected to the domain, a user may view other computers within the domain and may browse the shared files and folders available on the connected systems.

Windows XP users can browse Windows Network Domains by selecting the “My Network Places” option on the left side of an open window. you’ll create a replacement domain by using the Network Setup Wizard. Mac users using Mac OS X 10.2 or later can even hook up with a Windows Network by clicking the “Network” icon on the left side of an open window. this can allow you to browse local Macintosh and Windows networks using the SMB protocol.
