2. A Brief History Of ICANN

The Internet Corporation for Assigned Names and Numbers (ICANN) plays a critical role in the infrastructure of the digital world, particularly in domain name management and IP address allocation. Here’s a brief history of ICANN:

1998: Formation

It was established on September 18, 1998, as a nonprofit organization in response to a need for a more globally inclusive management of the Internet’s core resources. This need was identified and promoted by various stakeholders, including the U.S. government.

ICANN’s formation marked a significant transition from the previously U.S.-centric management under the Internet Assigned Numbers Authority (IANA), a function then performed under the auspices of the University of Southern California and supervised by Jon Postel, a key figure in the early development of the Internet.

The Early Years: Establishing Policies

In its early years, ICANN’s primary focus was on policy development for the domain name system (DNS). It introduced the Uniform Domain-Name Dispute-Resolution Policy (UDRP), which provided a mechanism for resolving disputes over domain name registrations. This was crucial in dealing with cases of domain squatting and trademark infringements.

2000s: Expansion of Top-Level Domains

The 2000s saw ICANN’s role expand with the introduction of several new top-level domains (TLDs) to accommodate the growing demand for domain names and diversify the domain name market beyond the original .com, .org, and .net. This expansion included country-code TLDs (ccTLDs) and generic TLDs (gTLDs), allowing for more specialized domains.

2010s: A Global Focus

The 2010s were defined by a major initiative to further increase the number of gTLDs, leading to a significant expansion in 2012 when it introduced over 1,300 potential new TLDs for application. This era also underscored a shift towards a more globalized approach in internet governance, reducing the influence of the U.S. government. In 2016, the U.S.

The Department of Commerce ended its formal relationship with ICANN, acknowledging its matured multi stakeholder governance model that included businesses, civil society, and governments from around the world.

Recent Developments and Challenges

In recent years, it has faced new challenges, including addressing the security of the DNS against increasing cyber threats and ensuring the integrity of global internet governance in an era of enhanced cybersecurity risks. The organization continues to work on improving DNS security, enhancing the accountability and transparency of its operations, and addressing issues related to internet privacy and the use of domain names.

Its evolution reflects the changing dynamics of internet technology and global politics, emphasizing the need for a collaborative approach to internet governance.

3. How Does ICANN Work?

ICANN (the Internet Corporation for Assigned Names and Numbers) functions as a central part of the internet’s global infrastructure by coordinating the Domain Name System (DNS), which links domain names with IP addresses. ICANN’s operations are built around a multistakeholder model, which includes an array of groups from different sectors all contributing to the decision-making process. Here’s an overview of how it works:

Multistakeholder Model

It operates on a multistakeholder governance model, which means it involves representatives from a variety of groups, including governments, civil society, academic institutions, the private sector, and technical communities. This model is designed to ensure that no single group has total control over the internet’s DNS and that the interests of the global internet community are considered.

Management of DNS

The core function of ICANN is to manage the DNS, which ensures that when you type a web address (like www.example.com), you are directed to the correct website. This system requires managing both the names (like ‘example.com’) and the numbers (the IP addresses that the names point to).

Allocation of IP Addresses

It allocates blocks of IP addresses to five Regional Internet Registries (RIRs), which in turn distribute these addresses to users in their respective regions. This structured distribution ensures orderly growth and management of IP addresses, facilitating efficient internet connectivity worldwide.

Assignment of Top-Level Domains (TLDs)

It approves and coordinates TLDs, which are the suffixes at the end of a domain name, such as .com, .org, or .net, as well as country-code TLDs like .uk or .jp. It also manages the introduction of new generic TLDs, expanding the domain space to include tags like .blog, .tech, and .name.

Policy Development

ICANN helps develop policies concerning the technical coordination of the DNS to ensure its secure, stable, and resilient operation. The policy development process typically involves extensive consultation and discussion among stakeholders to reflect the diverse interests of the global internet community.

DNS Security and Stability

It plays a crucial role in maintaining the security and stability of the DNS. This involves setting and enforcing standards and procedures for registrars and registries, managing the root zone of the DNS, and implementing measures to secure the DNS against cyber threats.

ICANN Meetings and Public Participation

ICANN holds three public meetings each year in different regions of the world to ensure global participation and transparency. These meetings are open to anyone and provide a forum for policy development and discussion of issues affecting the internet’s naming and addressing systems.

ICANN’s Supporting Organizations and Advisory Committees

It has several supporting organizations and advisory committees that focus on specific aspects of internet governance, such as the Generic Names Supporting Organization (GNSO) which deals with policy development for generic TLDs, and the Governmental Advisory Committee (GAC) which provides advice on public policy issues related to the governance of the DNS.

4. What Does ICANN Do?

4.1. Domain Names & DNS

Computers communicate through numerical codes, enabling them to access websites via their unique IP addresses. To simplify web browsing for users, domain names such as ours, vinahost.vn, are linked to these IP addresses.

Facilitating this connection, the domain name system (DNS) organizes the correlation between domain names and IP addresses. Given the inherent interdependence of these components, it’s logical for ICANN to oversee their management.

It primarily handles two key components of domain names: the second-level domain (SLD) and the top-level domain (TLD).

SLDs typically represent brands and are distinct. For instance, in vinahost.vn, “vinahost” serves as the SLD. The TLD, on the other hand, is indicated by “.vn”.

TLDs are categorized based on various factors such as geographic location, purpose, age, and operator, providing users with insights into their characteristics.

Generic top-level domains (gTLDs) encompass extensions like .com, .org, and .net.
Country code top-level domains (ccTLDs) include examples such as .uk, .ca, and .fr.
New top-level domains (nTLDs) consist of extensions like .agency, .bio, and .charity.
Sponsored top-level domains (sTLDs) feature extensions like .google and .apple.

With assistance from the Generic Names Supporting Organization and the Country Code Names Supporting Organization, ICANN oversees both SLDs and TLDs. These organizations are among the numerous bodies within ICANN that provide policy guidance.

4.2. IP Addresses

As you can see, IP addresses appear as sequences of numbers and occasionally letters, separated by dots or colons depending on their version. Each IP address serves to pinpoint a specific device and its network, facilitating communication between devices.

It oversees the allocation of IP addresses through a central repository, which is distributed among five Regional Internet Registries worldwide. Assisted by the Address Supporting Organization, an advisory committee within ICANN, it offers recommendations and aids the board in IP address management.

4.3. Root Servers

At the heart of the DNS hierarchy lies the root zone, housing 13 root servers responsible for managing domain name requests across various top-level domains.

Since its establishment in the ’90s, IANA, now a department of ICANN, has supervised the DNS root zone. Primarily, it delegates management duties for each root server to distinct organizations.
