The domain structure can be broken down into top-level domains (TLD), or first-level domains, and sub-Level domains (SLD). The most common TLDs include .com, .info, .org and .net. A TLD is also sometimes represented as a country code such as .us, .ca and .de. SLDs are domains that are created in order to connect a related page to the main website. SLDs are subdivisions of a TLD that represent the specific product, service, organization or business. They direct someone to a specific part of an existing website and eliminate the need to register a completely separate domain.

One of the best things about domain names is that they are unique. This uniqueness is also what makes some domain names quite valuable. A new domain name is recorded in a database, and each record in the database must be unique. The owner and registrar of a domain name are found through directories such as WHOIS.com.
