Format: subdomainname.secondleveldomain.topleveldomain.countryleveldomain
Example: subexample.example.com.uk
A domain is an address name of a website that is used for internet users to manually navigate to the website with the URL bar of any web browsers. As a name itself, a domain name is a string that identifies a realm of administrative autonomy, authority or control. 
Domain names are often used to identify services provided through the Internet, such as websites, email services and more. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer. 
There are 4 levels of domain, 2 levels are optional: a subdomain (optional), a second-level domain, a top-level domain and a country-code level (optional)
==Subdomain==
A subdomain is a domain that is part of a domain. Subdomains are defined by editing the DNS zone file pertaining to the parent domain.
