Subfolder name first on main URL
I would like to register a website for the publication division of my organization. It is having different independent, but related components such as online journals. I wanted to show them as a part of the main domain name, but they should appear first on the URL with a dot followed by the main domain URL. How can I do it? E.g. IIT, Madras is having many special units such as library, Alumni cell etc. While the main URL of IIT, Madras is www.iitm.ac.in, the units are given as library.iitm.ac.in, alumni.iitm.ac.in This will help in projecting those units. How can I do it? Does it require separate Domain Name Registration for this? Kindly help.
