注册商与域名注册局有直接的关系，并有权销售域名。通过互联网名称与数字地址分配机构（ICANN）认证后才能成为注册商，而这要求他们符合一定的商务和技术要求。

Background

NSI Cooperative Agreement & the SRS

From 1993 to 1998, Network Solutions (NSI) was the only Registrar and Registry Operator for the .com, .net and .org top level domain names (TLDs), based on a Cooperative Agreement between NSI and the National Science Foundation (NSF). The Department of Commerce (DOC) extended and amended the Cooperative Agreement with NSI when the contract expired in 1998. Under the new Cooperative Agreement, NSI would continue to serve as a Registry Operator, but would implement a Shared Registry System (SRS) by June 1, 1999, meaning that multiple registrars could be accredited by a new non-profit organization that was to be created to take over the technical management of the DNS. Five new registrars were to be chosen by the new corporation to test the SRS. The Agreement was modified twice in order to adjust the date of the deployment of the SRS from June 1 to June 25, 1999, to include a registration fee for new domain names ($9 for one year and $18 for two years), and to include the Registrar License Agreement.

ICANN的注册商委任政策

1998年11月，商务部正式承认 ICANN为负责DNS技术管理的新的民间非营利组织。其职责包括监督部署和过渡至SRS、开发并执行能够保证注册系统竞争性的注册商委任程序，并且维护互联网的稳定性和安全性。

1999年3月4日， ICANN 董事会采纳了有关顶级域.com、.net和.org的注册商委任政策申明。在该政策下，希望参与SRS测试平台项目的注册商需要缴纳2500美元的费用，而其他所有注册商申请人需要缴纳1000美元的费用。没有被选为参加测试平台的申请人将进行常规委任。

SRS测试平台项目的参与者

ICANN从1999年3月11日至4月8日接受了SRS测试平台项目的申请。1999年4月21日，ICANN宣布以下5个注册商已经获选参加测试平台：

1. 美国在线
2. 注册商互联网委员会
3. France Telecom/Oléane
4. Melbourne IT
5. Register.com

此外，ICANN还宣布了在SRS测试平台项目完成以后将接受委任的其他29家公司的名称。测试平台项目在1999年11月30日结束。将被委任为“测试平台后注册商”的企业名单详见[1]。

ICANN自此后继续接受了注册商委任申请。这里是完整的ICANN 委任注册商名单。

The Registrar Accreditation Agreement (RAA)

ICANN implemented a new version of Registrar Accreditation Agreement (RAA) on March 17, 2001 effective until March 21, 2009. A new revision was again introduced on March 21, 2009 with 17 amendments. Some of the revisions include:

• improved enforcement tools to ensure full compliance with the ICANN contract and policies
• expansion of requirements for reseller agreements
• additional requirements for audit and data escrow
• additional requirements to ensure precise contact information
• new notice requirements
• provisions for termination

Registry and Registrar

Vertical Separation

When the U.S. Department of Commerce amended Network Solutions' (NSI) cooperative agreement and implemented the Shared Registry System (SRS), the DOC also put a condition on the renewal of NSI's contract: the company would be able to automatically renew its contract for another four years as long as it separated its registry and registrar businesses. This was done in order to promote more competition in the domain space.

In 2000, Verisign purchased Network Solutions for $16 billion. Verisign decided to sell the registrar business to Pivotal Private for $100 million in order to concentrate on its new registry business. This move enabled Verisign to re-negotiate its registry agreement with ICANN. On April 16, 2001, a Revised Registry Agreement for .com, .net and .org was adopted. Number 23 (C) Fair Treatment of ICANN-Accredited Registrars on the revised agreement stipulated, "Registry Operator shall not act as a registrar with respect to the Registry TLD. This shall not preclude Registry Operator from registering names within the domain of the Registry TLD in compliance with Section 24. This also shall not preclude an affiliate (including wholly-owned subsidiaries) of Registry Operator from acting as a registrar with respect to the Registry TLD, provided that Registry Operator complies with the provisions of Subsection 23(E)." Sub-section E also stated that Registry Operators must ensure that their assets and revenues would not be utilized to advance the interests of their affiliate registrars against other accredited competitor registrars.

The separation of ownership, or vertical separation, was also implemented to all un-sponsored TLD registry operators to maintain registrar competition.

ICANN's Policy Change on Vertical Separation

On November 5, 2010, the ICANN Board passed a resolution allowing the removal of registry-registrar cross-ownership restriction for existing and new gTLDs. Further explanation on this issue, vertical integration, is available here.

RADAR

ICANN maintains Registrar Contact Information Database, called RADAR, that Registrars can log into to perform Domain Name transfers and other functions.

On 29 May 2014, ICANN announced that a security breach had occurred and RADAR would be taken offline until a review was conducted. Registrar's passwords, usernames, and email addresses may have been accessed. ICANN stated that they had no evidence unauthorized logins had occurred but was resetting all Registrar passwords as precautionary measure. ICANN stated the database will be offline for at least two weeks while the organization conducts a security audit of RADAR and other ICANN processes.
