Hostname. A hostname is a plaintext name identifying a host in a given domain. On a local area network (LAN), a server's hostname might be a nickname like mailserver1. On the internet, a hostname makes up part of a web address and has three parts: the subdomain, domain name and top-level domain. For example, the hostname whatis.techtarget.com consists of the subdomain whatis, the domain techtarget and the top-level domain .com.
Allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.
