Domain name registrar market share
Until 1999, Network Solutions (NSI) operated the com, net, and org registries. It was the domain name registry operator for these domains as well as the sole registrar. However, several companies had developed independent registrar services. One such company, NetNames, invented the idea of a commercial standalone domain name registration service in 1996. Registrars introducing the concept of domain name sales and other associated services, effectively introducing the retail model into the industry and assigning a wholesale role to the registries. NSI assimilated this model, which ultimately led to the separation of registry and registrar functions.
In October 1998, following pressure from the growing domain name registration business and other interested parties, NSI's agreement with the United States Department of Commerce was amended. This amendment required the creation of a shared registration system (SRS) that supported multiple registrars. This SRS officially opened on November 30, 1999 under the supervision of ICANN, though there had been several testbed registrars using the system since March 11, 1999. Since then, over 500 registrars have entered the market for domain name registration services.
Of the registrars who initially entered the market, many have continued to grow and outpace rivals. Go Daddy is the largest registrar. Other successful registrars include eNom, Tucows and Melbourne IT. Registrars who initially led the market but later were surpassed by rivals include Network Solutions and Dotster.
Designated registrar
An end-user cannot directly register a domain and manage their domain information with ICANN. A designated registrar must be chosen. Prior to 1999, the only com registrar was NSI, but the approval of the SRS opened up the opportunity for other companies to be designated as registrars.
Each ICANN-accredited registrar must pay a fixed fee of US$4,000 plus a variable fee. The sum of variable registrar fees are designed to total US$3.8 million.
Only the designated registrar may modify or delete information about a domain name. The competition that the SRS created enables end users to choose from many registrars offering different services at varying prices. It is not unusual for an end user to switch registrars which invokes a domain transfer process governed by specific domain name transfer policies.
When a registrar registers a com domain name for an end-user, it must pay a maximum annual fee of US$6.86 to VeriSign, the registry operator for com, and a US$0.20 administration fee to ICANN. Most domain registrars price their services and products to address both the annual fees and the administration fees that must be paid to ICANN. Barriers to entry into the bulk registrar industry are high for new companies without an existing customer base.
Many registrars also offer registration through reseller affiliates. An end-user registers either directly with a registrar, or indirectly through one or more layers of resellers. As of 2008, the cost generally ranges from a low of about $7.50 per year to about $35 per year. The maximum period of registration of a domain name is generally 10 years.
Some registrars are offering longer periods of up to one hundred years, but such offers involve the registrar renewing the registration for their customer. The one hundred year domain name registration would not be in the official registration database. Some packages of Internet services, such as web hosting, include the domain registration in the total package pricing.
Domain name register
See also: Domain name registrar
A domain name registry, is a database of all domain names registered in a top-level domain. A registry operator, also called a Network Information Center (NIC), is the part of the Domain Name System (DNS) of the Internet that keeps the database of domain names, and generates the zone files which convert domain names to IP addresses. Each NIC is an organisation that manages the registration of Domain names within the top-level domains for which it is responsible, controls the policies of domain name allocation, and technically operates its top-level domain. It is potentially distinct from a domain name registrar. [1]
Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA), which manages the top of the DNS tree by administrating the data in the root nameservers.
IANA also operates the .int registry for intergovernmental organisations, the .arpa zone for protocol administration purposes, and other critical zones such as root-servers.net.
IANA delegates all other domain name authority to other domain name registries such as VeriSign.
Country code top-level domains (ccTLD) are delegated by IANA to national registries such as DENIC in Germany, or Nominet in the United Kingdom.
Operation
Some name registries are government departments (e.g., the registry for Sri Lanka nic.lk). Some are co-operatives of Internet service providers (such as DENIC) or not-for profit companies (such as Nominet UK). Others operate as commercial organizations, such as the US registry (nic.us).
The allocated and assigned domain names are made available by registries by use of the WHOIS system and via their Domain name servers.
Some registries sell the names directly (like SWITCH in Switzerland) and others rely on separate entities to sell them. For example, names in the .com TLD are in some sense sold "wholesale" at a regulated price by VeriSign, and individual domain name registrar sell names "retail" to businesses and consumers.
Policies
Allocation policies
Generally, domain name registries operate a first-come-first-served system of allocation but may reject the allocation of specific domains on the basis of political, religious, historical, legal or cultural reasons.
For example, in the United States, between 1996 and 1998, InterNIC automatically rejected domain name applications based on a list of perceived obscenities.
Registries may also control matters of interest to their local communities: for example, the German, Japanese and Polish registries have introduced internationalized domain names to allow use of local non-ASCII characters.
Dispute policies
Domains which are registered with ICANN registrars, generally have to use the Uniform Domain-Name Dispute-Resolution Policy (UDRP), however, Germany's DENIC requires people to use the German civil courts, and Nominet UK deals with Intellectual Property and other disputes through its own dispute resolution service.
Cost of registration
The cost of domain registration is set by each individual registry.
Third-level domains
Domain name registries may also impose a system of third-level domains on users. DENIC, the registry for Germany (.de), does not impose third level domains. AFNIC, the registry for France (.fr), has some third level domains, but not all registrants have to use them, and Nominet UK, the registry for the United Kingdom (.uk), requires all names to have a third level domain (e.g. .co.uk or .org.uk)
Domain Sub-Registration
Registrants of second-level domains sometimes act as a registry by offering sub-registrations to their registration. For example, registrations to .fami.ly are offered by the registrant of fami.ly and not by GPTC, the registry for Libya (.ly).

Really these are the top domain companies. Now recently I have heard about Register domain name which is upcoming. They are giving first preference to customers and excellent performance.
