Difference between a domain and sub domain.?
1. Domains: the small business owner.
2. SubDomains: Once someone buys a domain, they can make all the subdomains they want, for free. Sometimes web designers will create subdomains for their clients – but they are not owned by the business owner – they are owned by the web designer. You as a small business owner have no rights to a subdomain on some else’s website.
