What is ICANN and Its Role in Domain Names?

The Internet Corporation for Assigned Names and Numbers (ICANN) is a global nonprofit organization responsible for coordinating the maintenance and procedures of several databases related to the namespaces of the Internet.

ICANN plays a crucial role in the domain name system (DNS) by overseeing the allocation of IP addresses and domain names, ensuring that every domain name is unique and leads to the correct website.

Main Functions of ICANN

• Domain name management: ICANN ensures the proper coordination of domain name registrations worldwide.
• IP address allocation: It regulates how IP addresses are assigned, ensuring no conflicts or overlaps.
• Accreditation of registrars: ICANN accredits registrars who are authorized to sell and manage domain names to the public.

Main Domain Registrars and Their Role

Domain registrars are companies accredited by ICANN that allow individuals and businesses to purchase and manage domain names. Some of the leading domain registrars include:

• GoDaddy: One of the largest and most well-known domain registrars, offering domain registration, hosting, and other web services.
• Namecheap: Known for its affordability and excellent customer service, Namecheap provides domain registration, SSL certificates, and more.
• Google Domains: Google offers a simple and streamlined domain registration service with the added benefit of Google integration.
• Bluehost: Although primarily known for hosting, Bluehost also offers domain registration and is especially popular with WordPress users.

Part Registrars and Resellers

Main registrars often have part registrars or resellers who offer domain registration services under their umbrella. These resellers work under the authorization of larger registrars but may offer different pricing or bundles for domains.

• ResellerClub: A popular example, ResellerClub offers domain registration services as a reseller for larger registrars. It allows businesses to create their own domain and hosting services.
• HostGator: Although primarily a hosting company, HostGator acts as a reseller for domains, providing registration services to its customers.

By choosing a reliable registrar or reseller, users can secure domain names while benefiting from added services like web hosting, SSL certificates, and privacy protection.
