Exploring the Concept of Domain Names: The Gateway to Internet Presence

Every time you type a web address into your browser – whether it’s a news portal, an e-commerce site, or a government portal – you are using a domain name. It seems simple enough, but behind that brief string of text lies an entire technical and legal architecture that keeps the internet organised, accessible, and functioning for billions of users worldwide. For law students studying intellectual property and internet law, understanding domain names is not merely a technical exercise; it is essential groundwork for grasping trademark disputes, cybersquatting, and the broader question of who controls identity on the internet.

What is a domain name? 🔗

At the most basic level, a domain name is a human-readable address used to locate a website or other internet resource. Every device connected to the internet is assigned a numerical identifier called an Internet Protocol (IP) address – a string of numbers such as 192.0.34.65. Computers communicate using these numbers, but for humans, remembering a long numerical sequence for every website is impractical. Domain names solve this problem by providing easy-to-remember text-based equivalents. As ICANN explains, the system uses letters rather than numbers and links a precise series of letters to a precise series of numbers, so that a website can be reached via a name like “icann.org” rather than its underlying IP address.

A domain name therefore does two things simultaneously: it serves as an address that routes internet traffic to the correct server, and it serves as an identifier – a name that users associate with a particular organisation, brand, or service. As the growth of e-commerce has shown, this dual function has made domain names commercially significant assets in their own right.

The Domain Name System (DNS): how it works 🔗

The Domain Name System (DNS) is the underlying infrastructure that makes domain names functional. It operates as a distributed, hierarchical database that translates domain names into IP addresses – a process called DNS resolution. When you type a web address into your browser, your computer queries a DNS server, which looks up the corresponding IP address and directs your connection to the correct server. According to MDN Web Docs, if a local DNS cache does not already hold the answer, the query travels up the DNS hierarchy until it reaches an authoritative name server that can provide the correct IP address.

The DNS is not a single centralised database. It is distributed across thousands of servers worldwide, all of which share and synchronise records. Changes to a domain’s records typically propagate across the entire internet within 48 hours, making the system both flexible and resilient.

The structure of domain names: TLDs and second-level domains 🔗

Domain names follow a hierarchical structure that is read from right to left. According to ICANN, the DNS forms a tree-like hierarchy where every domain name is composed of labels separated by dots. The rightmost label is the Top-Level Domain (TLD), and what appears immediately to its left is the Second-Level Domain (SLD).

Take the address www.supremecourt.gov.in as an example familiar to Indian law students. Here, .in is the TLD (India’s country-code TLD), gov is a second-level label indicating the government sector, supremecourt is the registered domain name, and www is a subdomain. Each level of the hierarchy is managed by a different entity, and responsibility cascades downward from the root.

Types of top-level domains 🔗

TLDs fall into several categories, each with a distinct purpose:

Generic TLDs (gTLDs) are the most widely recognised. The original seven gTLDs – .com, .edu, .gov, .int, .mil, .net, and .org – were created in the 1980s, as noted by ICANN’s TLD archive. Of these, .com, .net, and .org are open for registration by anyone; the others are restricted to specific entities such as government departments (.gov) or military organisations (.mil).

Country Code TLDs (ccTLDs) are two-letter codes assigned to individual countries and territories based on the ISO 3166-1 standard. India’s ccTLD is .in, managed by the National Internet Exchange of India (NIXI). These domains signal a geographic or national connection and are often subject to local registration rules.

Sponsored TLDs (sTLDs) are operated by specific communities or industries, such as .edu for educational institutions or .aero for the aviation sector.

Since 2012, ICANN has also introduced hundreds of new generic TLDs such as .law, .tech, .shop, and .blog, vastly expanding the namespace available to registrants. As of early 2026, the IANA root database includes over 1,500 active TLDs.

From monopoly to open market: the evolution of domain name registration 🔗

The history of domain name registration is as much a story about governance and competition as it is about technology. In the early days of the internet, domain name administration was informal and academic. That changed significantly in September 1991, when Network Solutions, Inc. (NSI) began operating the DNS registry under a sub-contract with the U.S. Defense Information Systems Agency (DISA). Initially, NSI allocated domain names in TLDs such as .com, .org, .net, .gov, .edu, and .mil at no charge.

In 1993, the National Science Foundation (NSF) awarded NSI an exclusive contract to manage registrations in the three open TLDs – .com, .net, and .org – making it the sole registrar in the world for these domains. This monopoly position came under strain when, in 1995, the NSF permitted NSI to charge fees for domain registrations. NSI charged $100 for a two-year registration, a figure widely criticised as excessive. The backlash against NSI’s pricing and its entrenched monopoly became a key catalyst for reform.

The solution came in the form of a new institution. In 1998, the U.S. Department of Commerce contracted with the newly incorporated Internet Corporation for Assigned Names and Numbers (ICANN) to administer the DNS on behalf of the global internet community. ICANN was established as a private, non-profit corporation with a mandate to oversee TLDs, manage domain name registrations, and resolve trademark disputes over domain names. Crucially, ICANN’s formation opened domain name registration to competition: by 1999, multiple registrars were accredited to sell domain names, ending NSI’s exclusive grip on the market.

ICANN’s role today 🔗

Today, ICANN functions as the coordinating authority for the internet’s naming and addressing systems. It draws up contracts with each TLD registry, runs an accreditation programme for registrars, and maintains the stability and security of the DNS root zone. ICANN does not sell domain names directly; instead, it accredits over a thousand independent registrars worldwide – organisations like GoDaddy, BigRock, or Namecheap – who sell domain names to individuals and businesses. ICANN also oversees the dispute resolution framework, having adopted the Uniform Domain Name Dispute Resolution Policy (UDRP) in 1999 in cooperation with the World Intellectual Property Organization (WIPO). In 2016, the United States formally ended its stewardship contract with ICANN, placing oversight of the DNS fully under ICANN’s independent, multistakeholder governance structure.

Domain names as legal identities: the Indian perspective 🔗

From a legal standpoint, domain names are no longer merely technical addresses – they have become business identifiers with significant commercial value. The landmark Indian Supreme Court decision in Satyam Infoway Ltd. v. Siffynet Solutions Pvt. Ltd. (2004) addressed precisely this question. The Court held that while domain names originally served only as internet addresses, the growth of commercial activity online had transformed them into business identifiers – capable of distinguishing the goods and services of one company from those of another. In doing so, the Supreme Court recognised domain names as intellectual property deserving protection analogous to trademarks.

Under Indian law, domain names can be registered and protected as trademarks under the Trade Marks Act, 1999, provided they meet the standard conditions for trademark registration – distinctiveness, capability of graphical representation, and ability to distinguish goods or services. A registered domain name can be enforced against infringement, while even an unregistered domain name may receive protection through the common law remedy of passing off. The Delhi High Court’s early ruling in Yahoo! Inc. v. Akash Arora & Anr. (1999) – where the court restrained the defendant from using “yahooindia.com” on the basis of passing off – illustrated that Indian courts were alert to domain name misuse well before any dedicated statutory framework existed.

For dispute resolution at the international level, ICANN and WIPO administer the UDRP, which allows trademark holders to challenge domain name registrations made in bad faith without going through conventional litigation. For disputes specific to the .in ccTLD, India has its own IN Domain Dispute Resolution Policy (INDRP), administered through the National Internet Exchange of India.

Why domain names matter beyond technology 🔗

A domain name is, in many respects, a business’s front door on the internet. For companies that operate entirely or substantially online, the domain name is often as valuable as a trademark or trade name. The first-come, first-served nature of domain registration – where no prior approval of ownership or distinctiveness is required – creates conditions for abuse. Cybersquatting, the practice of registering domain names that correspond to well-known trademarks with the intent to sell them at a premium or mislead users, has generated extensive litigation and policy debate in India and globally. The tension between the open registration system and the need to protect existing intellectual property rights lies at the heart of domain name law.

At the same time, domain names embody a unique characteristic that trademarks do not: they are inherently global. A trademark registered in India grants protection only within Indian territory, but a domain name is accessible from anywhere in the world. This borderless nature, as noted by IP practitioners, is precisely why international frameworks like the UDRP, developed through collaboration between ICANN and WIPO, were necessary – domestic trademark law alone cannot fully address the global reach of a domain name dispute.

What do you think? As domain names continue to evolve – with hundreds of new TLDs entering the market and internationalised domain names enabling scripts like Devanagari – do existing intellectual property frameworks in India adequately protect businesses from domain name abuse? And given that a domain name is globally accessible but trademark protection remains territorially limited, should there be a single international treaty specifically governing domain name rights?
