Editing Domain name (section)

==Uses in website hosting==
The domain name is a component of a [[uniform resource locator]] (URL) used to access [[website]]s, for example:
*URL: <nowiki>http://www.example.net/index.html</nowiki>
*Top-level domain: <nowiki>net</nowiki>
*Second-level domain: <nowiki>example</nowiki>
*Hostname: <nowiki>www</nowiki>

A domain name may point to multiple [[IP addresses]] to provide server redundancy for the services offered, a feature that is used to manage the traffic of large, popular websites.

[[Web hosting services]], on the other hand, run servers that are typically assigned only one or a few addresses while serving websites for many domains, a technique referred to as [[virtual web hosting]]. Such IP address overloading requires that each request identifies the domain name being referenced, for instance by using the [[HTTP request header field]] ''Host:'', or [[Server Name Indication]].
