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 Choose a Domain Name

Open the dictionary and pick a word – the .com of that word will almost certainly be gone. So, where do you begin when choosing a domain name that will help your business grow? NameExperts.com Director Joe Uddeme walks you through the whole process.   One of the most important decisions you’ll make about your business is the domain name you choose to acquire. The domain name you give your business is crucial because it becomes your identity on the web. You want it to reflect your brand and fit your business, but you also need it to be easy to find and promote. Acquiring a premium domain name is definitely the way to go, but choosing one can be difficult. What criteria should you be following to make sure you end up with the very best when you buy a domain name? This post is a little different to the others on the NameExperts blog – it’s a list of six key pointers to consider when choosing a domain name.   1. Pick a Short Name When You Choose a Domain What You Want to Avoid: When you’re just starting out playing with domain names to choose it can be tempting to combine all your ideas into one long domain name – like UsedCadillacsInTexas.com. However, while that may make it unique and descriptive, it may hurt your branding. What to Do Instead: A short name is easy to remember, easier to spell, and thus, has a better chance of becoming a household name. It also makes it easier when you want to branch out into branded items, or you want to create a logo, etc. Unfortunately, all the very easy 3-letter names were all taken as early as 1997, but there are plenty of others available that are appropriate. The shorter your domain name is, the easier it is to share through word of mouth. It’s also easier to type into your search bar, especially if you’re using a phone.   2. Pick Something Easy to Spell, Pronounce, and Remember What You Want to Avoid: A name that is difficult to spell can negatively impact your traffic because it can mean that users don’t land on your page. They might even end up with a competitor instead. You’ll also want to avoid using multiple spellings and the use of hyphens, numbers, or special characters. Your customers will often misunderstand numbers or misplace hyphens. People who hear your web address might not know whether you’re using a numeral or if it’s spelled out. What to Do Instead: This name needs to be easy to remember. Your customers need to be able to spell it correctly and pronounce it easily, so that they can easily share it with others (check out our guide to choosing a strong brand name for your business). Imagine you’re naming a child – you want something unique for your site, but you also don’t want a name that will create difficulties because of spelling or pronunciation. Every ‘Steve’ whose parents opted for ‘Steeyve’ or ‘Stëeve’ will tell you that being ‘clever’ with a name rarely works. If you absolutely need to include special characters or terms that are more difficult to spell in your domain name, make sure you register different variations of it to be safe. Some of the most famous and brandable names out there are extremely simple: Google. Facebook. Amazon. Apple. These are giants who created an excellent product or service, but who also knew how to brand themselves by acquiring premium domain names.   3. Use Relevant Keywords What You Want to Avoid: A word of caution here – if your domain is entirely made up of keywords, you run the risk of creating a brand that sounds too generic or unrecognizable. Especially if you’re starting a blog or a personal page, you need something with a bit of personality. What to Do Instead: You’ll notice that a lot of the heavy players have names that are composed of two words, and one of them is usually a keyword. That is a very clever choice, because a) it’s descriptive of your business, b) it majorly contributes to SEO, and c) it makes your name easy to remember. So, if you’ve got an interior design business, for example, you’ll want a premium domain that ideally includes a relevant keyword, like “design”, “interior”, “decorator”, “home”, “style”, etc. That will tell your potential customers all they need to know about your business. Your name is also likely to pop up in whatever Google search they try for “interior design” or similar keywords. If your business is local, you might consider including your city or state in your domain. That way, customers in your area can find your name and remember it easier. Often, when doing keyword research for your business, you’ll find that city and state will most likely be included.   4. Avoid Anything Confusing or Inappropriate What You Want to Avoid: You want to pay attention to not pick a name that is confusing (either because of spelling or sheer peculiarity), awkward, or inappropriate. If the initials of your business make up an inappropriate word, scrap the name immediately. What to Do Instead: Pay attention to what a domain looks like when you spell it out, if it’s made of multiple words. You’ll be surprised at how many other words you may inadvertently spell. Example: your name is Marc and you’re a rapper. www.marcraps.com isn’t great, is it? The other thing to look out for is picking a name that has no relation to your line of business. That can be very confusing.   5. Avoid Names that Already Exist or Are Trademarked What You Want to Avoid: Don’t go ahead with a name that is extremely similar to an existing one or that is trademarked, because a) that is confusing for your customers and you risk losing traffic, and b) you may, someday, be served with a legal notice that may create problems. What to Do Instead: However, there is a caveat here. If the name is already trademark-protected, that’s a bit of a dead-end. There can’t be another Burger King, for example. If, however, the domain name you want is just taken by someone else, there are ways around that, and you are still able to buy a domain name that is already owned.   6. Choose a .com TLD, but Purchase All Available Extensions What You Want to Avoid: If you only acquire the domain name you want and no other similar ones, you run the risk of having someone else purchase other variations of your domain. They will get the traffic that should have been directed towards your page. What to Do Instead: The most popular domains are .com ones and they are the most widely used, so it’s the ideal premium domain to acquire. But your work doesn’t stop here. Once you’ve bought that, you also want to purchase every other available variation of your domain name. For example, let’s say your domain name is www.carsforsale.com. You should try to buy www.carsforsale.net, www.carsforsale.org, www.carsforsale.biz, etc. That way, no one else can take these domains and possibly steal traffic that was meant to go your way. Once you have these domains, you can make sure the traffic redirects to your main .com domain. Check out our guide to TLDs (top level domains). The Bottom Line When Deciding How to Choose a Domain Name Choosing a domain name can be a delicate process. Pick the wrong one, and your business may suffer. Pick the right one, and it can catapult you into quick notoriety, or at least it can help make branding easier. The most important things to remember when choosing what domain to acquire is that it should be something easy to spell and remember, it should be non-trademarked, and it should ideally include a keyword. If you manage to find the perfect one, purchase every variation to make sure that you can take advantage of 100% of the traffic going to these domains. Buying premium domain names for a business can be pretty complex, which is why many people turn to an expert domain broker for help. Brokers know all the ins and outs of securing a great name and are adept at negotiating the best price for the buyer.

What is AI Domain – And Does the .ai TLD Work for Your Business?

Super-popular since the launch of chatGPT, .ai domain names are an attractive option for tech and machine learning businesses. Domain name expert Joe Uddeme explains the pros and cons.   The .ai domain extension is a top-level domain (TLD – check out our comprehensive guide to domain levels) that originated as the country code domain for Anguilla, a picturesque Caribbean island. Initially designated for local use, the .ai domain has since evolved far beyond its geographic roots. Today, it is recognized as a specialized domain extension tailored for companies involved in artificial intelligence and related technologies. The .ai domain stands as a beacon of innovation and technological prowess, particularly in the realms of artificial intelligence and technology. The .ai domain extension has become synonymous with cutting-edge advancements, making it a sought-after choice for businesses and organizations aiming to showcase their expertise in AI and related fields. In this post, we’ll look at the originals of the .ai TLD and discuss why it might be right for your business when you want to buy a premium domain name. Key Takeaways Origins of the .ai TLD What are the benefits of a sector-specific domain name? Popular .ai brands thriving today Is the .ai TLD safe?   Brief History of AI Domain The .ai domain has a fascinating history that dates back to 1995, when it was introduced as the country code top-level domain (ccTLD) for the island of Anguilla. Initially, the domain was restricted to businesses based in or tied to Anguilla, but in 2009, it was made available worldwide without restrictions. Since then, the .ai domain has gained popularity among tech companies and organizations globally, representing artificial intelligence and innovation. Today, the .ai domain is a sought-after domain extension, with many to establish a strong online presence.   AI Domain Names: Significance and Purpose AI domain names, which end with the .ai extension, are more than just web addresses—they are powerful tools for brand recognition and online presence. For tech companies and organizations, a .ai domain name signals a commitment to innovation and technological excellence. These domain names are particularly valuable for businesses in the AI sector, as they instantly convey a focus on artificial intelligence. By choosing a .ai domain, companies can create a unique and memorable web address that reflects their dedication to advancing technology and AI. This not only helps in establishing a strong online identity but also in attracting a tech-savvy audience. The concept of ‘ai domain growth’ is closely tied to the adoption and future prospects of .ai domains, driven by factors such as innovation in AI technologies, the number of AI-focused startups, and the consumer perception of .ai branding.   Benefits of .AI Domains SEO Benefits for AI-Related Topics One of the standout benefits of .ai domains is their potential to enhance search engine optimization (SEO) for AI-related content. Google treats certain country code top-level domains (ccTLDs), including .ai, similarly to generic top-level domains (gTLDs) like .com, .net, and .org. This means that a .ai domain can be just as effective in reaching users who are searching for AI-related information. By leveraging a .ai domain, businesses can improve their visibility in search engine results, thereby attracting more visitors interested in artificial intelligence. This SEO advantage, combined with the inherent brand recognition of the .ai extension, makes this kind of domain name branding a powerful asset for companies in the AI sector. Anyone involved in domain portfolio management today is quite likely to have one or more .ai domain names in their collection – if only for future-proofing reasons.   Popular AI Domain Examples The .ai domain extension has been embraced by numerous influential companies and organizations within the tech industry. Here are some notable examples that showcase the versatility and appeal of this domain extension: Open.ai Open.ai is a pioneering research organization dedicated to advancing artificial intelligence to benefit humanity. Their website, open.ai, serves as a hub for their groundbreaking work and mission in the AI field. By using the .ai domain extension, Open.ai underscores its commitment to innovation and leadership in artificial intelligence. Facebook.ai Facebook.ai is the dedicated platform for Facebook’s extensive research and development in artificial intelligence. The website provides a comprehensive overview of Facebook’s AI initiatives, including their cutting-edge AI-powered tools and technologies. The .ai domain extension helps Facebook highlight its focus on AI advancements and its role in shaping the future of technology. AI.google AI.google is Google’s showcase for its artificial intelligence research and development efforts. The website offers detailed information on Google’s AI projects, tools, and technologies, reflecting the company’s dedication to pushing the boundaries of what AI can achieve. The .ai domain extension reinforces Google’s position as a leader in the AI industry.   AI Domain vs Other Domain Extensions When it comes to choosing a domain extension, tech companies and organizations have several options, each with its unique advantages. The .ai domain stands out as a niche domain extension specifically associated with artificial intelligence and machine learning. While .com remains the most popular and widely recognized domain extension, .ai is rapidly gaining traction among businesses focused on cutting-edge technology. On the other hand, .io is another popular choice for tech companies, but it doesn’t carry the same strong association with AI as the .ai domain does. For businesses aiming to highlight their expertise in artificial intelligence, the .ai domain offers a distinct and memorable web address that sets them apart from the competition. (Need help securing a domain name that seems out of reach? Check out our guide to the top domain brokers for 2025). Comparison to .com Domain The .com domain is the most widely recognized and popular domain extension, with over 160 million registered domains. In contrast, the .ai domain has around 533,000 registered domains as of October 2024. While .com is a more established and traditional domain extension, .ai is gaining popularity as a niche domain extension for tech companies and organizations focused on artificial intelligence and machine learning. Google treats some ccTLDs, including .ai, .me, and .biz, the same way as .com, .net, and .org, making .ai a viable option for businesses looking to establish a strong online presence. Comparison to .io Domain The .io domain is a popular domain extension for tech companies, but it is not as closely associated with artificial intelligence as .ai. While .io is a more established domain extension, .ai is gaining traction as a niche domain extension for tech companies and organizations focused on artificial intelligence and machine learning. The .io domain has around 1.5 million registered domains, compared to the .ai domain’s 550,000. Why not check out our guide to choosing a domain name? It’s full of helpful tips and advice.   Acquiring and Configuring an AI Domain Acquiring and configuring a .ai domain is a straightforward process. To register a .ai domain, you can search for available domain names on a domain registrar’s website and proceed to check out. The registration process typically involves verifying the availability of the domain name, choosing your registration term, and paying the registration fee. Once the registration is complete, the domain name will be registered and available for use. To configure your .ai domain, you can set up website hosting, email hosting, and other services to establish a strong online presence. By securing a .ai domain, businesses can effectively signal their commitment to innovation and technological advancement in the AI industry.   AI Domain Safety and Security Features When it comes to online security, the .ai domain extension offers robust features to ensure a safe and reliable web presence. Here are some key safety and security measures associated with .ai domains: Overview of Safety Features Domain Name Dispute Resolution Policy: The .ai domain extension adheres to the Uniform Domain-Name Dispute-Resolution Policy (UDRP), providing a structured process for resolving disputes related to domain name registrations. This policy helps protect domain owners from potential conflicts and ensures fair resolution. Domain Name System Security Extensions (DNSSEC): The .ai domain extension supports DNSSEC, which adds an extra layer of security to domain name lookups. DNSSEC helps prevent certain types of cyber attacks, such as cache poisoning, by ensuring the authenticity of the DNS responses. Two-Factor Authentication: Many registrars offering .ai domain registrations provide two-factor authentication (2FA). This security feature requires users to verify their identity through an additional method, such as a mobile device, adding an extra layer of protection against unauthorized access. Domain Locking: Some registrars offer domain locking services, which prevent unauthorized changes to the domain name registration. This feature ensures that only authorized individuals can modify domain settings, reducing the risk of domain hijacking. WHOIS Protection: WHOIS protection services are available through some registrars, which hide the registrant’s contact information from public view. This feature helps protect domain owners’ privacy and reduces the risk of spam and identity theft. Overall, the .ai domain extension is a secure and reliable choice for businesses and organizations aiming to establish a strong online presence in the tech industry. With these comprehensive safety features, .ai domains provide peace of mind and robust protection against various online threats.   Who Uses .AI Domains? .ai domains are embraced by a diverse array of businesses and organizations within the AI and technology sectors. Here are some of the key users: Tech Companies: Many tech companies opt for .ai domains to establish a robust online presence and enhance brand recognition. The .ai extension underscores their commitment to technological innovation. AI Startups: For AI startups, a .ai domain is a perfect fit. It conveys a sense of cutting-edge technology and forward-thinking, which is crucial for attracting investors and customers. Research Institutions: Universities and research institutions often use .ai domains to highlight their work in artificial intelligence. This helps in building a strong online presence and gaining recognition in the academic and research communities.

It helps them stand out in a crowded market and signals their expertise in AI. Domain consultants advise businesses on the best strategy when planning a domain name portfolio.
