Host name

The host name clearly identifies a unique computer in its network. In a URL, the host name comes straight after the designation of the protocol and before the domain name. In most cases, the host name is allocated according to the purpose for which the computer is used. The most familiar example of this is the “www” in URLs. This designation has become established as the host name of the computer on which the WWW service runs, i.e. the web server. Whether the website goes with or without the “www” in front of the domain name will depend on the provider’s configurations. (sometimes both are possible).
