In computer networking, a hostname is a label that is assigned to a device connected to a computer network.
Contents
Description
This label is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet.
Hostnames may be simple names consisting of a single word or phrase, or they may be structured.
Domain Name System
Hostnames that include DNS domains are often stored in the Domain Name System together with the IP addresses of the host they represent for the purpose of mapping the hostname to an address, or the reverse process.
On the Internet, hostnames may have appended the name of a Domain Name System (DNS) domain, separated from the host-specific label by a period ("dot").
In the latter form, a hostname is also called a domain name.
Fully qualified domain name
If the domain name is completely specified, including a top-level domain of the Internet, then the hostname is said to be a fully qualified domain name (FQDN).
