An example of domain name structures.
The domain name has 3 structures as following;
Part 1 Sub Domain Name

Organizations are able to assign any name to the Second-Level domain name which must not be duplicated the existed one. As the name is the first keyword users recognize. The name should be short, easy to remember, concise, easy to spell and relate to the organization, products or services introduced on the website.

For example ".ac.th"
