A. Definition subdomain
Previously I have discussed know the identity of the domain. And time will be explained on the identity of the subdomain. Domains and subdomains is a trunk that does not separate, when there must be a subdomain domain. So what is a subdomain?

If the domain is the name or label that serves to identify the network on the Internet by defining a control area based DNS. Domains are used to give the name of a website that serves to call the domain. Needed for calling the URL and recorded dibrowser, such http://your-domain.com

While a subdomain of the domain name. Subdomain serves as the domain naming were added to the main domain. Such as: blogspot.com is the main domain name, while subdomains are youraddress.blogspot.com. domain and its subdomains illustration can be seen clearly below.

Domain: blogspot.com
Subdomains: your address
Combined into the URL: http: // www.youraddress.blogspot.com

The point is the subdomain is the addition of the domain name with the addition of the symbol period (.).

B. Existence Subdomain
Subdomains allow the existence of a second party that has a website using the domain has been provided by the first party as a URL for rent, Internet or purchased. If we see a miraculous subdomain, this usually occurs on the Website with free category, such as blogspot.com domain owned by Google, Yahoo and blogdetik.com owned wordpress.com.

When we want to create a blog or build a website with free manner, then we simply list the domain owner. If google we simply list at http://www.blogger.com. Once registration is complete, the final step is to create a subdomain or the name of the new address listed in column naming subdomain when we signed up. When accepted, we can use the URL, such as URL http://www.youraddress.blogspot.com.
