Domain Domain names typically consist of three or more names separated by dots, e.g. ‘company.com’ or ‘company.co.uk’. Thus ‘company.com’ specifies the domain in Web addresses such as ‘www.company.com’ or e-mail addresses such as ‘manager@company.com’. A fully qualified domain name is a hierarchy. The most specific part of the domain name is the hostname, which is listed most left. Then the domain name is listed. And finally the top level domain that signifies which country or what kind of organisation the domain name belongs to.
Hostnames follow a so-called naming convention. These are guides that tell what kind of hosts should be called what.
World Wide Web services are by naming convention called www servers and their domain name will begin with ‘www’.
Domain names are usually acquired through a local Internet service provider (ISP).
