There aren’t many people today who don’t know what a domain name is – but few actually understand how they really work. In this post, NameExperts.com Director Joe Uddeme explains what’s going on behind the scenes.

 

A domain name is what you type when you want to visit a website. For example, you type “Google.com” into your web browser, and it takes you directly to Google to search for stuff. But a lot happens behind the scenes to ensure the domain name you type takes you to the correct website.

In fact, it’s all pretty complicated – and interesting, too. If you want to buy a premium domain name worth in the tens or even hundreds of thousands, having clear insight into what you’re actually paying for might be a good idea. This article will explain what happens and demystify how the world of URLs and the web works.

Key takeaways:

How A Domain Name Leads You To A Website On the Internet

The Internet is an extensive network of computers connected to each other via cables; each computer on this network can communicate with others. Every computer is identified by a unique Internet Protocol (IP) address, which consists of four numbers separated by periods, e.g., 192.168.1.2.

Each website is hosted by a specific computer or server. When you want to visit that website, you need to point to the IP address of the computer hosting it. But IP addresses are difficult to remember. Imagine you had to memorize the unique IP addresses of all the websites you visit; that’ll be impossible, which is why domain names were invented.

A domain name is a human-readable name pointing to a specific IP address on the web. Whenever you type a domain name into your browser, it queries a vast database called the Domain Name System (DNS) and gets the corresponding IP address of the website you want to visit.

The Domain Name System is akin to a phonebook in your home containing your friends’ names and phone numbers. You don’t remember all your friends’ phone numbers; you just need to know their names. Whenever you need a specific number, you check for the name and get it.

This is precisely what the Domain Name System accomplishes; you type a domain, and it gives the correct IP address to your web browser. Your browser fetches the data from the server using that IP address and shows it to you.

 

Parts Of A Domain Name

A domain name has three main parts: top-level domain (TLD), second-level domain, and subdomain.

1. Top-Level Domain

The top-level domain (TLD) is the last segment of text in a domain name. The most popular TLDs you should be familiar with include

  • .com
  • .net
  • .co
  • .edu
  • .org

Yet, there are over 1,500 TLDs you can choose from. A lot of them are assigned to specific countries, such as;

  • .uk (United Kingdom)
  • .tv (Tuvalu)
  • .br (Brazil)
  • .ca (Canada)
  • .cn (China)
  • .de (Germany)

There are many other random TLDs such as .website, .book., .dog, .attorney, and .band. A popular one today is the .ai domain name, which has been a hit with tech companies.

2. Second-level domain (SLD)

This is the middle part of the domain name. It is a unique word or phrase identifying the website you want to visit. This part of the domain plays the biggest role in branding an online business. It’s also important in search engine rankings.

3. Subdomain

A subdomain is the part that comes before the main domain. They are attached to the main domain and separated by a period, e.g., blog.example.com, support.website.com.

Subdomains function like independent websites but are attached to the main site. For instance, you can have an online store or a blog attached to your main business site.

 

Who Manages the Domain Name System (DNS)

The Internet Corporation for Assigned Names and Numbers (ICANN) is the agency responsible for managing the global domain name system. It is a nonprofit organization that enacts policies for creating and managing domain names. It permits companies called domain registrars to sell domain names on its behalf.

Technically, you don’t own any domain that you use. You’re leasing it from ICANN (via your domain registrar) and controlling it as long as you renew the registration. If your registration expires, another person can take control of the domain – although with a little effort it’s possible to secure a domain name forever (sort of).

 

How To Buy A Domain Name

To buy a domain, you can head to any domain registrar’s website and check if someone else has not registered the domain name you want. If so, you can immediately pay for it and start using it.

If the domain name you want has already been registered, don’t fret. You can hire a domain name broker to help you trace, contact the owner, and negotiate a possible purchase. Domain brokers have experience arranging domain sales, so they’ll help you pay a fair price for the domain you want.

 

Tips For Choosing A Domain Name

  • It should be short and simple. Longer domain names are more difficult to remember. Try and choose a strong domain name that will match your business goals and ambitions.
  • Avoid using hyphens and numbers in the domain name.
  • Use keywords related to your line of business. This helps improve your branding and search rankings.
  • A .com TLD should be your first option. If that isn’t available, use other popular TLDs such as .co and .net. The more popular the TLD is, the easier it will be to promote.

Frequently Asked Questions about Domains

How long can I register a domain name for?

The maximum registration period for a domain name is 10 years. But you can renew it every 10 years and keep control of the domain.

What is a premium domain name?

They are high-quality domains that people often buy to flip for a higher price later. Demand for premium domains is high, and the price increases over time, making them good investments.

Can you sell your domain name?

Yes, you can sell your domain name anytime you want to. You can do that yourself or enlist a domain broker to find a buyer for the best price.

How do you find the owner of a domain?

You can identify a domain’s owner by querying the public WHOIS database, which contains contact information about the registered owner of every domain.

What happens if I don’t renew my domain name?

Registrars usually give a 30-day grace period in which you can reclaim the domain. Your domain will be auctioned on the market if that period runs out.

What To Do After Buying a Domain Name

Congratulations! You bought a domain name. But now what? In this post, domain name expert Joe Uddeme explains what to do next to keep your domain name protected – and extract its full value.   “I have a domain name. Now what?” – this is a very common question people ask. The fact is, a domain name is pointless if you don’t do anything with it! After buying a domain, many things will run through your mind, and choosing how to use it productively can be confusing. However, don’t fret. This article will guide you on what to do after purchasing a domain name. Do it right, and you can leverage your domain name and build it into an attractive asset. Do it wrong, and you’ll waste 20 bucks on the temporary ownership of something you can’t even touch.   Key takeaways: What is web hosting and why do you need it? Building a website and a brand you can leverage Attracting online customers to your new business Planning your exit strategy Before we proceed, let’s run through how to buy a domain in the first place.   Acquiring Your Domain Buying a domain has become more simple than ever. In 2025, it’s just a few clicks and a swift online transaction. The first step is to choose a domain name you like that is relevant to your business. Afterwards, you can check if it’s available to buy immediately. Find a domain registrar accredited by the Internet Corporation for Assigned Names and Numbers (ICANN), the organization overseeing all domain names on the Internet. If the domain name is available, you can purchase it immediately from an accredited registrar. The price depends on how high the demand for the domain name is. If the domain name has already been claimed, you need a different approach. You can check domain marketplaces to see if the owner has possibly listed the domain for sale (see our list of the best domain marketplaces). Otherwise, you can possibly contact the owner to negotiate a deal. If this is out of your comfort zone and you have a high-value premium domain name in your sights, check out an experienced domain name broker with a great track record. For more details on securing a domain name, check our in-depth article about how to buy a domain name. What To Do After Buying A Domain Name You have acquired a domain name and have taken the first step in building your web presence. There are many other things to do after buying the domain, and we’ll outline them below. 1. Get Web Hosting Setup After buying a domain name, the first thing to consider is hosting a website with it. You’ll need a web hosting package from a reliable company. The company will host your website on its servers for a fee, and your website will be accessible once someone types your domain name into their web browser. Web hosting has become a walk in the park, at least in terms of getting started. You can get reliable web hosting for a few dollars monthly, and the price keeps going down as computing capacity increases around the globe. Sometimes, a domain registrar also offers web hosting services, meaning you can buy a domain name and a hosting package from the same platform. Otherwise, you can buy them separately and point your domain name to your hosting company’s servers. 2. Connect Your Domain to Your Hosting Connecting your domain to your hosting provider is relatively easy. You can do it via two methods: Changing the nameservers to those of your web hosting provider. Adding a DNS A record. Either method involves changing the domain name system (DNS) configurations from your domain registrar. Your registrar allows you to directly change the nameservers from its default to the one provided by your hosting company. You can also point your domain to the hosting company’s nameservers by adding a DNS A record. It’s the same action but with two different approaches. 3. Create an Email Address with Your New Domain Instead of using a common email address ending with “Gmail.com,” “Yahoo.com,” or “AOL.com,” you can use one ending with your custom domain name. It makes you look more professional and shows people you’re serious about your business. Many domain registrars also offer email hosting, so you can pay for it and create custom emails directly. Otherwise, you can choose an external email provider and change your domain’s DNS MX records to point to its mail servers. 4. Build Your Website and Brand The best way to put a domain to work is to create a website with it. It can be any type of website, such as a blog or online store. Creating a website is usually complex, but there are ready-made tools that make the process as easy as it can get. You can use a designated website builder like WordPress, Wix, Weebly, Squarespace, etc. WordPress is the most common tool for building websites because of its versatility. You can use it to create virtually any type of website you want. Follow these steps: Install WordPress on your web hosting account (many hosting providers offer one-click WordPress installation). Afterwards, log into your WordPress dashboard to begin customizing your website.

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.
