Domain name registration (4)
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 infinite number of 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 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.

Technical
requirements and process
In the process of registering a
domain name and maintaining authority over the new name space created,
registrars use several key pieces of information connected with a domain:
- Administrative contact. A registrant usually designates an administrative contact to manage the domain name. The administrative contact usually has the highest level of control over a domain. Management functions delegated to the administrative contacts may include management of all business information, such as name of record, postal address, and contact information of the official registrant of the domain and the obligation to conform to the requirements of the domain registry in order to retain the right to use a domain name. Furthermore, the administrative contact installs additional contact information for technical and billing functions.
- Technical contact. The technical contact manages the name servers of a domain name. The functions of a technical contact include assuring conformance of the configurations of the domain name with the requirements of the domain registry, maintaining the domain zone records, and providing continuous functionality of the name servers (that leads to the accessibility of the domain name).
- Billing contact. The party responsible for receiving billing invoices from the domain name registrar and paying applicable fees.
- Name servers. Most registrars provide two or more name servers as part of the registration service. However, a registrant may specify its own authoritative name servers to host a domain's resource records. The registrar's policies govern the number of servers and the type of server information required. Some providers require a hostname and the corresponding IP address or just the hostname, which must be resolvable either in the new domain, or exist elsewhere. Based on traditional requirements (RFC 1034), typically a minimum of two servers is required.
