Most business owners never think about DNS or hosting until something breaks. Then suddenly they’re on hold with a hosting company, being asked questions they can’t answer, while their website sits offline.
This post is a quick primer. Nothing technical. Just enough to know what’s what.
There are three pieces to every website. They’re separate things, often managed in separate places, and they have to work together.
- Your Domain
Your domain is your address. It’s the “yourdomain.com” part.
You register it through a company called a registrar. GoDaddy is one of the most common.
Owning a domain doesn’t mean you have a website. It just means you own the address. - Your DNS
DNS stands for Domain Name System. Think of it as a settings panel that tells the internet where to find your website.
Here’s why it exists. Humans navigate the web using domain names like “yourdomain.com.” But computers navigate using numbers, called IP addresses. An IP address looks something like 142.250.80.46.
DNS is the translator. It takes your domain name and points it to the right numeric address.
These settings usually live at your registrar. But you can also manage them through a third-party DNS provider like Cloudflare, which some people prefer for performance or security reasons. - Your Hosting
Your hosting is where your website actually lives. It’s a server, which is just a computer somewhere that stays on all the time and stores your website files. These days, that “computer” likely lives in the “cloud” and isn’t actually a single server somewhere.
That server has an IP address. Your DNS settings point your domain to that address. When someone types your domain into a browser, DNS says “go to this IP address,” and the server delivers your website.
A critically important word about ownership
Your domain is arguably the most valuable piece of this whole setup. It’s your address on the internet. If you lose it, you lose everything connected to it: your website, your email, your Google rankings, all of it.
This happens more than you’d think.
Domains expire if nobody renews them. If your registrar has an old credit card on file, or renewal notices going to an inbox nobody checks, your domain can lapse. Someone else can register it the same day or shortly thereafter.
Sometimes the person who originally set up the domain leaves the company. Or the agency that built your site registered it under their own account instead of yours. Now you don’t control it. You have to ask nicely, or fight for it.
And then there’s the hostage situation. You decide to move to a new website provider. Suddenly the old one is slow to respond, drags their feet, or makes transferring the domain as difficult as possible. It’s not common, but it happens.
I’ve seen it.
The fix is straightforward. Make sure your domain is registered in your name, with your email address, under an account you control. Not your developer’s account. Not your old agency’s account. Yours.
Log in once a year. Confirm that auto-renew is on. Make sure the contact email is one you actually check.
That’s it. Five minutes of your time, once a year. It could save you an enormous headache down the road.
Why does any of this matter?
Because at some point, you’ll need to move your website to a new host. Or your DNS will need to be updated when something changes. Or you’ll want to add Google Workspace email to your domain.
And when that day comes, someone is going to ask you: “Who is your registrar? Where is your DNS managed? Who is your hosting provider?”
If you don’t know and you don’t have access, you’ll be stuck.
The good news is you only need to know three things. And now you do.
