Domain registration information is maintained by the domain name registries, which contract with domain registrars to provide registration services to the public
An end user selects a registrar to provide the registration service, and that registrar becomes the designated registrar for the domain chosen by the user.
Only the designated registrar may modify or delete information about domain names in a central registry database. It is not unusual for an end user to switch registrars, invoking a domain transfer process between the registrars involved, that is governed by specific domain name transfer policies.
When a registrar registers a “com” “ domain name” for an end-user, He must pay a maximum annual fee of “………..” to VeriSign, the registry operator for “com”, and a “………….” annual 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 2010, the retail cost generally range’s from a low of about “….” per year to about “….” per year for a simple domain registration, although registrars often drop the price far lower – sometimes even free – when ordered with other products such as web hosting services.
The maximum period of registration for a domain name is 10 years. Some registrars offer longer periods of up to 100 years,but such offers involve the registrar renewing the registration for their customer; the 100-year registration would not be in the official registration database.
