Domain Names: The Basics
A strong domain is the foundation of your business identity. Why? With the right domain, you're creating a lasting, professional online home for your company that can grow over time and (more importantly) you control.
On this page, we will discuss what a domain name is, how domain names work, and how to connect a domain name to a website or hosting provider.
What is a Domain Name?
A domain name is a unique and easy-to-remember string of words you type into a web browser to access a website. For example, you may have typed our simple domain “northwestregisteredagent.com” to visit our site, which ultimately brought you to this page.
Choosing the right domain early in the business formation process is crucial to building your company’s credibility and brand recognition. It’s also smart to secure similar domains—such as common misspellings—so competitors can’t capitalize on your name.
Why are Domain Names Important?
Beyond helping customers reach your site, a domain offers multiple benefits for establishing a strong business foundation.
- Gives you full ownership. Your own domain lets you carve out a distinct space on the internet and showcase your business.
- Establishes your company’s brand. A strong domain name reinforces your brand, boosts recognition, and helps your business stand out in a crowded market.
- Provides consistency. Using the same domain everywhere—your website, email addresses, and social media—creates a consistent brand presence customers can easily recognize.
- Offers professional credibility. A custom domain signals stability and legitimacy, which helps your business feel established and reliable to potential customers.
Parts of a Domain Name
A domain name is composed of several parts separated by periods, moving from general to more specific identifiers. Let’s take a closer look at each part.
- Top-Level Domain: A top-level domain (TLD) is everything that comes after the final dot–such as .com, .net, or .org. Classic TLDs like .com are familiar and trusted, while newer ones like .store or .design can make your business stand out.
- Second-Level Domain: A second-level domain (SLD) is the heart of your website–the part you own, and that identifies your brand. Your SLD can be your company name or a human name–whatever strikes your fancy. For example, our SLD is “northwestregisteredagent.”
- Subdomain (optional): A subdomain is the section that comes before your main website name (or SLD). Common subdomains include: www., shop., and blog. A website doesn’t need a subdomain to function—subdomains are just tools to organize content, separate services, or manage different parts of a site.
How Domain Names Work
Domain names work like a human-friendly label for your website, replacing its Internet Protocol (IP) address with something customers recognize as your brand. Here’s how that works.
Every website has a unique, numerical IP address. For example, a website might have an address like 123.456.789.10. But, it would be nearly impossible for humans to remember long sequences of numbers—especially considering there are millions of websites. Domain names bridge this gap by serving as stand-ins for those numbers, making them easier for people to remember.
From Domain Name to IP Address: How DNS Works
DNS (Domain Name System) is what translates your human-friendly domain name into an IP address that the internet understands. Basically, each time someone types a domain name into a web browser, DNS looks up the matching IP address, so the internet connects you to the correct website.

How to Connect a Domain to a Website or Host
To connect your domain to a website or host, you must update the domain’s DNS (Domain Name System) settings to point to the server hosting the website. What does that look like? Let’s break it down.
- Choose a web host. Your web host is where your site (and all its content) is stored. This may be the same company as your domain registrar—or a different one.
- Locate your DNS details. Once you’ve established your hosting account, you’ll need to find the DNS settings (or nameservers). These are typically listed under settings as “ns1.host.com and ns2.host.com”. Save these for later.
- Log in to your domain registrar. Sign in to the account where you purchased your domain and open the domain’s settings. Look for the DNS or Nameserver section.
- Update your nameservers. Replace the existing nameservers with the DNS information provided by your hosting provider.
- Wait for updates to take effect. Once updated, the changes can take anywhere from a few minutes to several hours to fully take effect.
Domain Name FAQs
Yes, you must have a domain for people to access your website. While you could utilize a temporary or platform-provided URL (such as yourbusinessname.webbuildingsite.com), that’s typically not ideal for businesses. A custom domain is essential for professionalism, branding, and long-term control of your business identity.
The best domain names are short, easy to spell, and closely tied to your products or services. For example, if you sell handmade jewelry, you may want to include the word “jewelry” or “jewels” in your domain name to increase traffic to your site and give potential customers a quick understanding of what your business sells.
You can change your domain name later, but it’s not ideal. Changing your domain can impact branding, SEO (Search Engine Optimization), and customer recognition. That’s why it’s essential to choose a domain name carefully early in the business formation process.
You do—as long as you register it in your business’s name and keep it renewed. To learn more about registering your domain, check out our complete domain registration guide.
