The 3 Types of Domain Names and Common Domain Extensions

When you buy a domain name, you purchase a piece of digital real estate. But what, exactly, are you getting for your money? NameExperts.com Director Joe Uddeme unravels the elements of a domain name – so you’ll have a clearer understanding of the architecture behind them.

 

A domain name is an address you type into your web browser whenever you want to visit a website. It is arguably one of the most important assets any business can own.

While ‘domain name’ is an all-encompassing term, a domain is actually made up of multiple parts. Understanding these elements can give you a clearer picture of the domain name investing world and ensure you’re well-informed before buying a domain name or asking a skilled domain broker to negotiate the purchase of one on your behalf.

What are domains?

A domain name is a human-readable address that directs you to a particular website available on the internet. It’s akin to the address for your official residence or workplace. When someone wants to visit you, they come to your address. Similarly, when someone wants to visit a website, they type in the domain address in their web browser.

Any domain name has four main components;

  1. Domain name: The name of the domain itself.
  2. Top-Level domain (TLD): The suffix that appears after the domain name, e.g., .COM and .NET.
  3. Subdomain: A domain that is part of another primary domain. It is also known as a third-level domain.
  4. Protocol: The system that specifies how information from the domain is transferred to your web browser. It is either HTTP (insecure) or HTTPS (secure).

Take https://www.nameexperts.com/, for example.

  • NameExperts is the domain name
  • .COM is the top-level domain
  • WWW is the subdomain
  • HTTPS is the protocol

The 3 Types of Domain Names

There are three main types of domains, including:

1. Top-Level Domains

A top-level domain (TLD) is the final section of a domain name. It is the last segment of text appearing after the dot symbol. For example, in Google.com, .COM is the top-level domain.

Ever since the world wide web’s inception, .COM has been the most common top-level domain. It was originally used to designate commercial businesses but has become the de-facto TLD for most websites.

Another popular TLD is .NET. It was initially meant for internet service providers and networks but is now available to anyone who wants it. Because NET signifies network and technology, this is an ideal option for technology companies.

Yet another well-known TLD is .ORG, which was originally used to designate not-for-profit organizations. Till today, most people associate this TLD with non-profit organizations and social causes rather than commercial businesses. The .ai TLD is another popular one today – especially for tech firms.

There are two main types of top-level domains;

Generic TLD

A generic top-level domain refers to domain name endings with three or more characters, the type that you’d most likely recognize. .COM, .NET, .ORG, .INFO, and other common domain endings fall under this category.

Before 2011, there were barely two dozen domain extensions classified as generic. That year, the Internet Corporation for Assigned Names and Numbers (ICANN) expanded the number of generic domain extensions from 22 to over 1,200, opening up more opportunities for individuals and businesses to acquire domain names.

Country-Code TLD

As the name implies, these are domain extensions associated with specific countries. ICANN assigns country domain endings to each formally recognized nation and sovereign state, and these nations collect a royalty on every sale of their assigned TLD. For example, Tuvalu, a small island nation, earns 1/12th of its annual income from its .TV domain extension.

Other popular examples of country domain endings include

  • .US for the United States of America
  • .AU for Australia
  • .DE for Germany
  • .CA for Canada
  • .CC for Cocos Islands
  • .AE for the United Arab Emirates (UAE), etc.

2. Second-Level Domains

A second-level domain is directly below a top-level domain in the domain hierarchy. It is the part of the domain name that comes right before the top-level domain. For example, in NameExperts.com, NameExperts is the second-level domain.

The second-level domain is usually a combination of words describing the business or service of the domain name owner – and it pays to match this to the name of your business whenever possible to strengthen your brand. In the above example, NameExperts describes the business of a professional domain name broker that helps customers to acquire valuable domains.

A second-level domain can include letters, numbers, and hyphens. Symbols are not allowed.

3. Third-Level Domains

The third-level domain, or subdomain, is the part of the URL that comes before the second-level domain. The most common subdomain is www., which refers to the world wide web. Third-level domains are not mandatory, so you can have a fully functional domain name without the www part.

Some website owners create third-level domains to represent a different section of their website. Examples include:

  • Shop.mywebsite.com refers to the e-commerce section of a website.
  • Blog.mywebsite.com refers to a blog attached to the website.
  • Support.mywebsite.com leads to the customer support section of a website.

Understanding Domain TLDs

A domain name is the most important property for anyone who conducts business online. Hence, it’s crucial to understand what they are and the different types of domain name extensions to use for a website.

The information above should help you figure out how to structure your domain, but if you need help, we’re experts at domain selection and helping you buy the perfect domain.

How to Buy a Domain Anonymously

Last updated: 15 October, 2025. Want to buy a domain name anonymously? You’re not alone – when the stakes are high, business buyers often want to stay out of the limelight. NameExperts.com Director Joe Uddeme explains how it’s done. What is Anonymous Domain Registration? Anonymous domain registration is a service that allows individuals and businesses to register a domain name without revealing their personal details in the public WHOIS database. Instead of displaying the domain owner’s personal information, such as name, address, and contact details, the registration uses generic proxy details. This approach provides an additional layer of domain buying privacy and security, ensuring that your personal information remains confidential. Understandably, it can be a very attractive option when trying to buy a premium domain name. Adding domain privacy can anonymize ownership details in the WHOIS database – which helps keep your name out of the picture. Anonymous domain registration is particularly valuable for protecting personal information, preventing unwanted solicitations, and maintaining confidentiality in sensitive situations. Key takeaways: Anonymous registration comes with many benefits Understand the role of WHOIS and regulatory issues Get top tips to boost security and domain name anonymity Work with an experienced domain broker to simplify the process and ensure you stay anonymous   Benefits of Private Domain Registration Registering a domain name anonymously offers numerous benefits, including: Protection of personal Information: Anonymous domain registration keeps your personal details, such as name, address, phone number, and email ID, private. This prevents your information from being publicly accessible in the WHOIS database. Domain privacy protection services can further obscure your personal information during registration. Prevention of spam and unwanted solicitations: By withholding ownership information, anonymous domain purchase helps you avoid unsolicited communication and spam. In business, information can be leveraged in numerous ways. Owning a domain name anonymously can be hugely advantageous. Enhanced security: Registering a domain anonymously adds an extra layer of security against cyber crimes like ransomware attacks and domain hijacking. You’ll boost both security and privacy by ensuring your contact information is protected. Confidentiality: Securing a domain name anonymously allows you to maintain secrecy in sensitive situations, such as buying premium domains – or selling them – and means you don’t have to reveal your identity. Emotional pricing elimination: Anonymous transactions eliminate emotional pricing by the seller based on the buyer’s identity and intention. If they know who you are, they may hike up the price, obscuring the true valuation. Discreet domain procurement: Companies can discreetly procure domains for internal products, brand expansions, or mergers without tipping off competitors. Understanding the WHOIS Database What is the WHOIS Database? The WHOIS database is a publicly accessible repository that stores information about registered domain names. Managed by the Internet Corporation for Assigned Names and Numbers (ICANN), this database contains essential details about domain owners, including their name, address, phone number, and email address. The primary purpose of the WHOIS database is to provide transparency and accountability in the domain name registration process. It allows users to look up information about a domain name and its owner, ensuring that the domain registration landscape remains open and trustworthy. Risks of Public WHOIS Data While the WHOIS database serves an important role, having personal details publicly available can pose several risks for domain owners: Spam and unsolicited contacts: With personal information readily accessible, domain owners may find themselves inundated with unwanted emails, phone calls, or physical mail from marketers and spammers. Identity theft: Cybercriminals can exploit the information in the public database to steal or hijack a domain, leading to potential financial and reputational damage. Privacy breaches: Publicly available personal information can be used to compromise a domain owner’s privacy and security, making them vulnerable to various forms of cyber threats. Once you realize the risks associated with publicly listing any domain names you acquire, you’ll likely want to protect your personal details through anonymous domain registration and other privacy measures. A skilled domain broker can help with all this. They will work on your behalf and protect you from risk. Check out our guide to domain name negotiations to find out how else domain brokers can help. Why Choose Anonymous Domain Registration? By choosing anonymous domain registration, you ensure your personal information is not publicly accessible in the WHOIS database. It’s basically like putting up a wall around your ownership that no one can peek over. It’s not difficult to register anonymously (your domain name broker can take care of this as part of their service), and by keeping your personal information private, you can sleep soundly at night. How to Register a Domain Anonymously There are several ways to ensure anonymous domain purchase, including: Using a domain registrar that offers anonymous registration: Services like Namecheap or Google Domains provide options that help conceal buyer identity when registering a domain name. Utilizing a proxy service: Services like Domains by Proxy or Uniregistry enable you to mask registration information, ensuring it remains private. Registering through a third-party service: Using a VPN or a domain anonymization service can help you register a domain without revealing your identity. Using a domain broker or marketplace: Engaging a domain broker or using a domain name marketplace can help conceal your identity. Using a domain privacy service: A domain privacy service can protect your personal information by replacing it with the service’s contact details. Talk to your broker about this. Some registrars offer free domain with hosting packages, which can lower overall costs and enhance the appeal of their services. Verifying Domain Privacy Protection You can easily explore the WHOIS database by entering your domain name in the search bar. This lets you see whether a website you own currently has domain privacy protection or not. What you want to find is a generic name, contact address, or email address that forwards messages to you. If you see any of your details in the Domain Information panel, consider enabling WHOIS privacy. You can also check with your domain registrar to see if they offer domain privacy protection services. Why Choose Anonymous Domain Name Registration? As mentioned, it adds a layer of security and protection for domain owners. By keeping personal information private, individuals and businesses can: Protect against cyber threats and unwanted exposure Prevent domain hijacking and fraud Maintain confidentiality in sensitive situations Enhance security against ransomware attacks and other cyber crimes Ensure personal information remains hidden from public view on WHOIS Pro tip: while anonymous domain registration has many benefits, always choose a reputable domain registrar that provides reliable privacy protection services. Additionally, be aware of the potential limitations and considerations when registering a domain name anonymously, such as specific restrictions or policies against this for certain domain extensions (TLDs). Simple Steps for Maintaining Domain Name Anonymity You don’t need to be a tech wizard to keep your name out of the picture. Here are five things to try: Use a VPN to mask your IP address and location. Use a secure email service that offers end-to-end encryption. Be cautious when sharing personal information online. Use a domain broker or a domain name marketplace to purchase a domain name anonymously (brokers such as NameExperts.com can help you make an anonymous offer to a domain owner, too). Consider using a proxy service to mask your personal information. If using escrow services to pay (recommended), make sure your broker knows how to handle this in a manner that keeps your identity secret from the seller. By following these tips, you can ensure that your personal details remain confidential and your online presence is secure. If you need help, your broker can streamline the process. Regulatory Considerations Compliance with ICANN Regulations ICANN regulations mandate that domain registrars collect and store accurate contact information for domain owners. This requirement ensures that the domain registration process remains transparent and accountable. However, ICANN also recognizes the need for privacy and allows for anonymous domain registration through the use of proxy services or private domain registration. To comply with ICANN regulations, domain registrars must: Collect and store accurate contact information: Registrars are required to gather and maintain up-to-date contact details for all domain owners. Provide options for anonymous domain registration: Registrars should offer services such as proxy registration or private domain registration to help domain owners protect their personal information. Educate domain owners on risks: It is crucial for registrars to inform domain owners about the potential risks associated with public WHOIS data and the benefits of opting for anonymous registration. Offer tools and services for privacy protection: Registrars should provide tools and services that enable domain owners to safeguard their personal information and maintain privacy. By adhering to these guidelines, domain registrars can ensure compliance with ICANN regulations while offering robust privacy protection options for domain owners. This balance between transparency and privacy helps maintain trust and security in the domain registration ecosystem. General Data Protection Regulation (GDPR) Implications General Data Protection Regulation (GDPR) has significant implications for domain registration and WHOIS data. Under GDPR, personal data cannot be shown without consent. This means that domain registrars must obtain explicit consent from domain owners before publishing their personal data in the WHOIS database. If you’re a domain owner, you can request that your personal information be removed from the WHOIS database by contacting your domain registrar. This regulation helps protect your personal information and ensures privacy. Limitations and Considerations when Seeking Domain Anonymity While anonymous domain registration offers many benefits, there are some limitations and considerations to keep in mind: Some domain extensions (TLDs), such as country-code top-level domains (ccTLDs), may have specific restrictions or policies regarding anonymous registration. Ensure that the domain registrar you choose has a reliable privacy protection service and a good reputation in the industry. Some domain registrars may require identification verification, but not all do. Domain privacy protection services may not be available for all domain registrars, so it’s essential to check with your registrar before purchasing a domain name. While private domain acquisition is possible in many cases, exceptions exist. An experienced domain broker can walk you through all available options.   About the author Joe Uddeme is Director and Principal of Name Experts, one of the world’s leading domain name brokerage services.

The Complete Guide to Buying Short Domain Names

Unlock the branding power of ultra-short domain names with help from industry expert Joe Uddeme. Discover why they matter, how to buy them, and what makes them valuable. When it comes to domain names, less is most definitely more. Most of the time, the shorter the name, the higher the price tag – because short domain names represent prime online real estate. Some of the most expensive domain names ever sold were four letters or less. These concise, memorable web addresses garner immense interest from businesses, entrepreneurs, and investors eager to build recognizable brands and carve out a market edge. Over recent years, most of the world’s shortest, most meaningful domains – especially those made up of just two or three characters – have been registered and are now labeled as “premium domain names.” If you want to buy a domain name that fits this bracket, their scarcity has driven demand and prices sky-high, turning the quest for short domains into a battleground for major brands and agile startups alike. In this post, we’ll look at great short names (and why some are less great), and we’ll delve into how buying one that has been registered for decades (and is even being used) might not be impossible. We’ll also look at the stories behind some of the largest deals – and, trust me, the sums involved will make your eyes water! Key Takeaways Short domains remain highly coveted assets for businesses seeking brand authority and a memorable web presence. Most premium short domains are already registered, but expert brokers can unlock rare buying opportunities through negotiation or connections. The real value of a short domain hinges on global usability, inherent meaning, and extension – some “short” names are more valuable than others. High-profile, big-money sales prove the ROI for companies investing in ultra-short web addresses. If you own a short domain, strategic sale planning and the right partners can help you capture maximum value.
