Editing Domain name (section)

===Business models===
Domain names are often seen in analogy to [[real estate]] in that domain names are foundations on which a website can be built, and the highest ''quality'' domain names, like sought-after real estate, tend to carry significant value, usually due to their online brand-building potential, use in advertising, [[search engine optimization]], and many other criteria.

A few companies have offered low-cost, below-cost, or even free domain registration with a variety of models adopted to recoup the costs to the provider. These usually require that domains be hosted on their website within a framework or portal that includes advertising wrapped around the domain holder's content, revenue from which allows the provider to recoup the costs. Domain registrations were free of charge when the DNS was new. A domain holder may provide an infinite number of [[Subdomain|subdomains]] in their domain. For example, the owner of example.org could provide subdomains such as foo.example.org and foo.bar.example.org to interested parties.

Many desirable domain names are already assigned and users must search for other acceptable names, using Web-based search features, or [[WHOIS]] and [[Domain Information Groper|dig]] operating system tools. Many registrars have implemented '''domain name suggestion''' tools which search domain name databases and suggest available alternative domain names related to keywords provided by the user.
