What is ICANN and why does it matter?

Who decides which domain extensions exist, which companies can sell domain names, and what happens when two brands fight over the same web address? One nonprofit organization sits at the center of all of it. ICANN, short for the Internet Corporation for Assigned Names and Numbers, is the global organization responsible for keeping the domain name system organized, stable, and fair. Without it, the internet would have no shared system for turning domain names into the addresses that computers use to find websites.

This article explains what ICANN does, what it does not do, and how its policies affect you as a domain owner. If you have ever registered a domain, renewed one, or wondered who makes the rules behind the scenes, this is the chapter that answers those questions.

What does ICANN stand for?

ICANN stands for the Internet Corporation for Assigned Names and Numbers. It is a nonprofit organization founded on September 30, 1998, and headquartered in Los Angeles, California. ICANN was created to take over responsibilities that were previously managed by a single researcher under a contract with the United States government.

The organization operates as a multistakeholder body, meaning it includes input from governments, private companies, technical experts, and everyday internet users. It is not a government agency. It does not answer to any single country. Today, ICANN has more than 400 employees and coordinates with over 1,000 accredited registrars across the globe.

What does ICANN do?

ICANN has four main jobs that affect the domain name system. Each one plays a direct role in how domain names are created, sold, and managed.

It manages the domain name system

The domain name system (DNS) connects human-readable domain names (like wemasy.com) to the numerical IP addresses that computers use to locate websites. ICANN coordinates the top level of this system. It manages the root zone, which is the master directory of all domain extensions like .com, .org, .net, and hundreds of newer ones. For a full explanation of how DNS works, see the chapter on what DNS is and how it works.

It accredits domain registrars

Companies that sell domains are called registrars, and each one must be accredited by ICANN. ICANN sets the rules registrars must follow, including how they handle customer data, how they process transfers, and how they respond to disputes. If a registrar breaks those rules, ICANN can revoke its accreditation.

It creates policies for new domain extensions

Every time a new domain extension launches, ICANN is behind the decision. In 2012, ICANN opened applications for hundreds of new generic top-level domains, leading to extensions like .app, .blog, and .photography. That expansion changed the landscape of domain extensions and gave brands more options beyond the traditional .com, .net, and .org.

That process was not without pushback. In 2011, a coalition of 79 major companies called the expansion a "commercial land grab," worried that brands would be forced to buy their name across dozens of new extensions just to protect their trademarks. ICANN moved forward anyway, and today there are more than 1,200 domain extensions available.

It handles domain disputes through the UDRP

When someone registers a domain name in bad faith, such as grabbing a trademarked brand name and trying to sell it back, ICANN provides a resolution process called the UDRP (Uniform Domain-Name Dispute Resolution Policy). It was developed with the World Intellectual Property Organization (WIPO) and offers a faster, cheaper alternative to court.

A trademark holder files a complaint, an independent panel reviews the case, and if the domain was registered in bad faith, it can be transferred or canceled. One well-known example involved the domain mickjagger.com, which was transferred to the musician after a bad-faith finding. The process typically takes a few weeks instead of months in a courtroom.

How does ICANN affect you as a domain owner?

You will probably never interact with ICANN directly, but its policies shape your experience every time you register, renew, or transfer a domain.

Your registrar answers to ICANN

The company where you bought your domain is an ICANN-accredited registrar. That means it follows ICANN's rules for pricing transparency, transfer policies, and customer protections. If your registrar fails to meet those standards, ICANN has the authority to step in.

WHOIS policies come from ICANN

When you register a domain, your contact information is stored in a public database called WHOIS. ICANN sets the rules for what information must be collected and how it can be accessed. For more on how this database works and what it reveals, see the chapter on what WHOIS is.

Dispute resolution goes through ICANN

If another brand claims your domain name infringes on their trademark, the dispute process follows ICANN's UDRP framework. Understanding how this process works helps you avoid registering domains that could put your brand at risk.

Transfer and renewal rules are standardized

ICANN requires a 60-day lock period after you register or transfer a domain, preventing unauthorized transfers. It also requires registrars to notify you before your domain expires. These standardized policies protect millions of domain owners from losing their web addresses unexpectedly. For a full breakdown of the registration process, see the guide on how to register a domain.

What does ICANN not do?

There are common misconceptions about ICANN's role. Here is where its authority stops.

ICANN does not register domains

ICANN does not sell domain names. It accredits the companies (registrars) that do. If you want to buy a domain, you go to a registrar, not to ICANN.

ICANN does not host websites

Hosting, website files, email servers, and the content on your site are all outside of ICANN's scope. It manages the naming and addressing layer only.

ICANN does not control internet content

ICANN cannot remove a website, block a page, or censor content. It cannot stop spam. Its authority is limited to the technical infrastructure that makes domain names and IP addresses work.

How do ICANN, registries, and registrars work together?

The domain name system has three layers, and ICANN sits at the top.

• ICANN sets the policies and coordinates the overall system. It decides which domain extensions exist and who can operate them.
• Registries manage individual domain extensions. For example, one registry operates .com, another operates .org, and others run newer extensions like .shop or .io. Each registry maintains the database of all domains registered under its extension.
• Registrars are the companies you interact with when you buy a domain. They are accredited by ICANN and work with registries to process your registration.

When you register a domain, you pay the registrar. The registrar pays a fee to the registry. And the registry operates under policies set by ICANN. This chain is how every domain name on the internet gets created, renewed, and managed.

How has ICANN changed WHOIS and privacy policies?

For years, anyone could look up a domain in the WHOIS database and see the owner's name, address, phone number, and email. ICANN required this transparency as part of its registration policies. But that changed when the European Union's General Data Protection Regulation (GDPR) took effect on May 25, 2018.

GDPR forced ICANN to rethink how personal data was handled in WHOIS records. Registrars serving EU customers had to start masking personal information by default. Today, most WHOIS lookups show redacted contact details instead of full names and addresses. ICANN has been working on a replacement system that limits access based on "permissible purposes," meaning law enforcement and trademark holders may still request the data, but casual lookups would no longer reveal personal information. For a full explanation of how domain privacy works, see the chapter on what domain privacy protection is.

How does WEMASY help you manage your domain?

WEMASY's website builder includes a custom domain with every plan. You get domain registration, hosting, SSL, and email all under one subscription. Your domain connects to your website automatically, with DNS settings handled for you. If you already own a domain, you can transfer it to WEMASY or point it to your site. See what is included in each plan on the pricing page.
