Internet Corporation for Assigned Names and Numbers


The Internet Corporation for Assigned Names and Numbers (ICANN) is a nonprofit organization that coordinates the maintenance and allocation of unique identifiers for the global internet domain system. It is responsible for overseeing domain name registration, IP address allocation, and protocol parameters management. ICANN ensures the stability and security of the global internet’s address system, allowing users and devices to efficiently connect to the internet.


The phonetics for “Internet Corporation for Assigned Names and Numbers” using the International Phonetic Alphabet (IPA) are:/ˈɪn.tə ˌkɔr.pəˈreɪ.ʃən fər əˈsaɪnd ˈneɪmz ənd ˈnʌm.bərz/

Key Takeaways

  1. ICANN is a non-profit organization responsible for managing and coordinating the Domain Name System (DNS) to ensure the internet operates smoothly and securely.
  2. ICANN is also responsible for the allocation of IP addresses, ensuring the uniqueness and stability of internet resources globally.
  3. Through its open, multi-stakeholder governance model, ICANN develops and promotes policies surrounding the internet’s unique identifiers, involving various stakeholders such as governments, businesses, and public interest groups.


The Internet Corporation for Assigned Names and Numbers (ICANN) is crucial in maintaining the stability and reliability of the global internet infrastructure.

As a non-profit organization, ICANN oversees the domain name system (DNS), which ensures that domain names are translated into IP addresses, making it possible for users to access websites via human-readable URLs.

By coordinating these unique identifiers across the world, ICANN plays a vital role in preventing conflicts and promoting interoperability, fostering a unified and secure experience for all internet users.

Furthermore, ICANN’s multistakeholder model encourages cooperation and input from a diverse range of interests, contributing to the evolution and improvement of the internet ecosystem.


The Internet Corporation for Assigned Names and Numbers (ICANN) serves a critical role in maintaining the overall stability and functionality of the Internet. Its core purpose is to oversee the coordination and management of domain names and IP addresses, which are the fundamental elements that enable computers and devices to communicate with one another over the World Wide Web.

ICANN is a non-profit organization, dedicated to ensuring that the Internet remains a secure, reliable, and interoperable global network accessible to everyone. By maintaining a unique and universal naming system, ICANN plays a vital role in preventing potential conflicts, confusion, and misuse of domain names and IP addresses.

One of the primary responsibilities of ICANN is to coordinate the allocation and assignment of the Top-Level Domain (TLD) names and IP address blocks to the Regional Internet Registries (RIRs). Furthermore, it also oversees the processes of accrediting and managing the registrars responsible for registering domain names under various TLDs. Moreover, ICANN develops and enforces policies that govern the domain name system (DNS) and promote competition, while simultaneously upholding the security, stability, and resiliency of the DNS.

With its diverse, multi-stakeholder governance model, ICANN brings together different stakeholders such as governments, businesses, and civil society organizations to contribute and develop its policies, ensuring that the Internet remains a unified and trustworthy platform for global communication and commerce.

Examples of Internet Corporation for Assigned Names and Numbers

The Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization responsible for managing and coordinating the domain name system (DNS) and IP address allocation. Here are three real-world examples concerning ICANN’s role in the technological landscape:

Domain Name Registration:In 2016, ICANN implemented the New Generic Top-Level Domain (gTLD) Program, which significantly expanded the number of domain name extensions available for registration (e.g., .com, .org, .net). This allowed businesses and organizations to have more options in choosing a relevant and easily identifiable domain name. For example, a website like “” demonstrates a direct connection between ICANN’s gTLD program and practical domain name usage.

Security Enhancements for Domain Name System (DNS):In 2018, ICANN called for the deployment of the Domain Name System Security Extensions (DNSSEC) across the global internet infrastructure. DNSSEC adds a digital signature to the domain name system data, ensuring the data’s integrity and making it more difficult for hackers to carry out cyberattacks. Many organizations, including internet service providers, have since implemented DNSSEC, reducing the risk of DNS-based attacks like cache poisoning and phishing.

Internationalized Domain Names (IDNs):ICANN has played a pivotal role in the introduction and standardization of Internationalized Domain Names (IDNs). These domain names support non-Latin scripts, such as Arabic, Chinese, and Cyrillic alphabets, allowing for greater accessibility and inclusivity for users around the world. For instance, a Chinese business can now register a domain name using Chinese characters, making it easier for local customers to find and engage with the company online. This initiative by ICANN has bridged the digital divide and provided opportunities for global internet users to create and access websites in their native languages.

FAQs about Internet Corporation for Assigned Names and Numbers (ICANN)

1. What is ICANN?

ICANN stands for Internet Corporation for Assigned Names and Numbers. It is a private, non-profit organization responsible for coordinating the management and maintenance of the domain name system (DNS) and IP address allocation. Essentially, it oversees the assignment of domain names and IP addresses to ensure the internet’s stable and secure operation.

2. When was ICANN established?

ICANN was founded in 1998 and has played an essential role in managing the internet namespace since then.

3. What is the domain name system (DNS)?

The domain name system (DNS) is a system that translates website names (e.g., into IP addresses (e.g., for computers to understand and access the desired web content. DNS is essential for people to navigate the internet using easy-to-remember domain names rather than numeric IP addresses.

4. What is ICANN’s role in the domain registration process?

ICANN accredits and oversees domain registrars – the organizations that manage the registration of domain names. While ICANN does not register domain names directly, they provide the policies and framework for registrars to follow when registering, renewing, and transferring domain names.

5. What is an IP address, and why is it important?

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to the internet. It serves as an identifier and allows data to be transferred between devices. Without IP addresses, devices would not be able to communicate and exchange information over the internet. ICANN is responsible for managing the allocation of IP addresses to maintain a structured and stable internet.

6. How does ICANN maintain the security and stability of the internet?

ICANN ensures the security and stability of the internet by implementing policies and standards for domain name registration and IP address allocation. They also work closely with the global internet community to develop and implement measures that prevent malicious activities, enhance DNS security, and combat internet threats such as domain name abuse and cybercrime.
