Domains have two parts, the unique address, and the primary
domain designation. The primary designation refers to the
type of domain, such as .edu for educational institutions,
or .com for commercial websites. Upper level domains for
businesses typically use .com, .net, or .org domain
designations. More recently other domains have been
released, such as .com, .tv, .md and .info.
