Decoding the Digital World: A Deep Dive into What is ICANN and Its Impact on the Internet


What is ICANN? In its simplest form, the Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization responsible for coordinating the global internet’s systems of unique identifiers, ensuring the internet’s stability and secure operation. As an integral part of the internet ecosystem, ICANN plays a crucial role in maintaining the seamless and interoperable nature of the internet that we have come to rely on every day.

The history of ICANN

Early days of the internet and the need for an organization like ICANN

In the early days of the internet, the domain name system (DNS) and IP address allocations were managed by a few centralized entities. As the internet continued to grow exponentially, there was a pressing need for a more structured, inclusive, and globally coordinated organization to oversee these critical functionalities. This is where ICANN comes in.

Establishment of ICANN

ICANN was established on September 18, 1998, with the main goal of maintaining the overall stability and security of the internet’s domain name system. From the start, ICANN’s mandate has been to ensure that the internet remains a single, globally interconnected network.

Major milestones in ICANN’s history

Since its inception, ICANN has reached several significant milestones, including the creation of the first generic top-level domains (gTLDs), the introduction of Internationalized Domain Names (IDNs), and playing a prominent role in transitioning stewardship of the DNS away from the United States government (IANA transition).

Structure and organization of ICANN

Governing bodies within ICANN


ICANN Board of Directors

The ICANN Board of Directors is responsible for setting the organization’s strategic direction, financial management, and approving policies developed by its supporting organizations and advisory committees.


Supporting organizations

Consisting of three major groups – the Generic Names Supporting Organization (GNSO), the Country Code Names Supporting Organization (ccNSO), and the Address Supporting Organization (ASO) – these entities develop and recommend policies to the ICANN Board for approval.


Advisory committees

These committees provide advice and insights to the ICANN Board concerning various aspects of ICANN’s mandate, such as security, public interest, and government representation.

Stakeholder groups involved in ICANN



Governments participate in ICANN through the Governmental Advisory Committee (GAC), which provides advice to the ICANN Board on public policy issues related to ICANN’s responsibilities.


Civil society

Non-governmental organizations, academia, and individual internet users have a voice in ICANN’s policy-making process through various mechanisms, including the Non-commercial Users Constituency (NCUC) and At-Large Advisory Committee (ALAC).


Private sector

Businesses, intellectual property interests, and other commercial entities are represented in ICANN through stakeholder groups such as the Business Constituency (BC) and Intellectual Property Constituency (IPC).


Technical community

Experts from the internet engineering, cybersecurity, and other technical fields contribute to ICANN’s work and policy development through participation in various technical working groups and advisory committees.

Functions and responsibilities of ICANN

Domain Name System (DNS) management


Root server system

ICANN oversees the operation and maintenance of the root server system, which is the authoritative source for the DNS, ensuring the stability and secure operation of the internet.


Top-Level Domains (TLDs)

ICANN is responsible for introducing new generic and country-code top-level domain names (gTLDs and ccTLDs, respectively) and coordinating their policies and operations.


Internationalized Domain Names (IDNs)

ICANN has worked on the development and deployment of IDNs, enabling non-Latin scripts to be used in domain names and expanding the internet’s accessibility to users worldwide.

Internet Protocol (IP) address allocation


Role of Regional Internet Registries (RIRs)

ICANN collaborates with RIRs, which are responsible for the allocation and management of IP addresses within their respective regions.


IPv4 and IPv6 address allocation

ICANN works with RIRs to oversee the distribution and management of IPv4 and IPv6 addresses, ensuring the longevity and growth of the internet.

Protocol parameter assignment

ICANN, through its IANA functions, assigns and maintains protocol parameters critical to the functioning of internet protocols such as DNS and IP.

Ensuring the security, stability, and resiliency of the DNS

Through its various functions, ICANN plays a vital role in maintaining the overall security, stability, and resiliency of the DNS, ensuring the internet’s smooth operation and future growth.

ICANN and internet governance

Multistakeholder model of internet governance

ICANN embodies the multistakeholder model of internet governance, enabling diverse groups and interests to participate in the decision-making process, ensuring the internet remains open and globally interconnected.

ICANN’s role in global internet policy development

ICANN not only helps coordinate the DNS and IP addressing, but it also plays a significant role in developing global internet policies and advocating for the multistakeholder model in broader internet governance discussions.

Relationship between ICANN and other internet governance organizations


Internet Engineering Task Force (IETF)

ICANN works closely with the IETF, an open standards organization responsible for the technical development and standardization of internet protocols.


World Wide Web Consortium (W3C)

ICANN collaborates with the W3C, a global community that develops standards for the web, ensuring its accessibility and smooth operation.


Internet Governance Forum (IGF)

ICANN participates in the IGF, an annual event that brings together various stakeholders to exchange views and ideas on internet governance issues.

Challenges and controversies surrounding ICANN

Cybersecurity and the DNS

ICANN faces the challenge of ensuring the DNS remains secure and resilient as threats evolve and grow, necessitating ongoing innovation and collaboration with the global technical community.

Domain name disputes and intellectual property concerns

ICANN has been at the center of debates concerning domain name disputes, with rights holders and stakeholders seeking fair and effective mechanisms to resolve disputes and protect intellectual property interests.

Global representation and equity in internet governance

Ensuring equal and fair representation of all stakeholders in ICANN’s decision-making process is a perennial challenge, with concerns about the influence of specific interests or regions over the organization’s policy outcomes.

Future of ICANN in an increasingly globalized and technologically advanced world

ICANN will need to adapt to the ever-changing technology landscape, such as the emergence of quantum computing and decentralized networks, to ensure its continued relevance in the management of the global internet.


In conclusion, ICANN plays an integral role in the management and continued growth of the global internet. Its multistakeholder approach has allowed for an inclusive and collaborative decision-making process that fosters the internet’s security, stability, and resiliency. With the rise of new technologies and an increasingly interconnected world, ICANN’s importance as a facilitator and coordinator cannot be understated.

To address the future challenges of a rapidly evolving technology landscape, ICANN must continue to adapt, innovate and collaborate with the global internet community, ensuring the internet we know today remains vibrant and accessible for generations to come.
