The short answer
A domain is your website’s address, such as yourbusiness.com, which you rent yearly from a registrar. Hosting is the server where your website’s files live and are delivered to visitors. DNS connects the two by pointing your domain at your host. Always register the domain in your own business’s name and account, even if an agency manages it for you.
Key takeaways
- A domain is your address; hosting is where the website actually lives.
- DNS records point your domain at your website and your email.
- Register the domain in your business’s own account, with auto-renew on.
- Choose hosting for speed, security and support, not the lowest price.
What is the difference between a domain and hosting?
A domain is the address people type to find your website; hosting is the computer where the website actually lives. Think of the domain as your street address and hosting as the building. You need both, they are often bought from different companies, and DNS is the signpost that connects them.
| Part | What it is | Where it comes from | How it is paid |
|---|---|---|---|
| Domain name | Your address, such as yourbusiness.com | A domain registrar | Yearly renewal |
| DNS | Records that point the domain to services | Your registrar or a DNS provider | Usually included |
| Hosting | The server that stores and delivers your site | A hosting company or platform | Monthly or yearly |
| SSL/TLS certificate | Enables HTTPS, the padlock in the browser | Usually your host, often free | Often included |
| Email hosting | Mailboxes at your domain, such as hello@yourbusiness.com | An email provider | Per user, monthly or yearly |
Website builders such as Wix and Squarespace bundle several of these together, which is convenient but makes moving later harder. Our comparison of a custom website vs Wix and Squarespace covers that trade-off.
How do you choose and register a domain name?
Choose a domain that is short, easy to spell when heard aloud, and clearly connected to your business name, then register it through an established registrar in your business’s own account.
- Start with your business name. Avoid hyphens, numbers and unusual spellings that people will mistype.
- Pick the right extension. A .com works worldwide. Country extensions signal a local business; in Thailand, a .co.th address requires documents for a registered Thai company, while .com has no such requirement.
- Check trademarks and social handles before you commit, so you are not building on a name someone else owns.
- Register it in your business’s account, using a company email address that will outlive any one employee.
- Turn on auto-renew and keep the payment card up to date.
- Turn on domain lock and two-factor authentication, so nobody can transfer the domain away without your approval.
- Keep the login details safe in a password manager your business controls.
If you trade under more than one name or in more than one country, it can make sense to register the main variations and redirect them to your primary domain.
What is DNS, and which records should you know?
DNS, the Domain Name System, is the internet’s directory: it translates your domain name into the addresses of the servers that handle your website and email. You manage it through a small set of records, usually in your registrar’s or DNS provider’s dashboard.
| Record | What it does |
|---|---|
| A / AAAA | Points your domain to the IP address of your web server. |
| CNAME | Points one name to another, such as www to your main domain or hosting platform. |
| MX | Tells the world which service receives your email. |
| TXT | Holds verification codes and email authentication (SPF, DKIM and DMARC). |
| NS | Says which company’s servers hold your DNS records. |
When you change a record, the update spreads gradually as servers around the world refresh their copies. This often happens within minutes, but can take up to a day or two, depending on each record’s TTL (time to live). A common and painful mistake is changing the nameservers during a website move and forgetting to copy the MX records, which quietly stops your email.
Which type of hosting does a business website need?
Most business websites need fast, secure, managed hosting with reliable backups and real support; the cheapest shared plan is rarely the best value. The right type depends on how your website is built.
| Hosting type | Good for | Watch out for |
|---|---|---|
| Shared hosting | Very small, low-traffic sites on a tight budget | Slow when neighbours are busy; you handle much of the security |
| Managed WordPress hosting | WordPress sites that need updates and backups handled | Plugin choices can still slow or weaken the site |
| VPS or cloud server | Custom applications and higher traffic | Needs technical skill to configure and maintain |
| Static hosting with a CDN | Fast, custom-built marketing websites | Dynamic features need separate services |
| Website builder platform | Simple sites built in Wix, Squarespace or similar | Hosting is tied to the platform; moving means rebuilding |
A CDN (content delivery network) stores copies of your site in data centres around the world, so a visitor in Bangkok and a visitor in London both get a fast response. That matters for international businesses and for website speed generally. If you are weighing platforms, read WordPress vs a custom website.
Who should own your domain and hosting?
Your business should own your domain, without exception, and should have full access to its hosting. An agency or developer can manage both day to day, but the accounts should be yours, with them invited as users.
A common and painful problem is a domain registered years ago by a freelancer, a former employee or a previous agency in their own name. When that relationship ends, the business discovers it cannot change its website, cannot fix its email, and sometimes cannot even renew its own address.
- Domain: registered in your business’s name, in your account, with your contact details.
- DNS: accessible to you, even if your developer makes the changes.
- Hosting: either in your account, or managed by your agency with a clear written agreement that you can take a full copy of the site at any time.
- Records: keep a simple document listing where each service lives, who has access and when each one renews.
Ask any agency you are considering how they handle this; our guide to choosing a web design agency includes it among the questions to ask.
What happens if your domain expires or you want to move hosts?
If your domain expires, your website and email stop working, and if it is not renewed in time it can be released for anyone to register. Registrars usually offer a grace period after expiry, but its length and the cost of recovery vary by registrar and extension, so never rely on it.
Moving hosts, by contrast, is routine when it is planned:
- Take a full backup of files, database and any form submissions.
- Set up the site on the new host and test it on a temporary address.
- Lower the DNS TTL a day in advance, so the switch spreads quickly.
- Copy every DNS record, especially MX and TXT records for email.
- Switch the records, then confirm HTTPS works on the new host.
- Test forms and email, and keep the old hosting running for a short overlap.
Hosting and domain renewals are part of the running cost of any website, covered in our guide to website maintenance costs.

Questions
Is a domain the same as a website? +
No. The domain is only the address; the website is the set of pages stored on a hosting server. You can own a domain without having a website on it.
Can I keep my domain if I change web designer? +
Yes, as long as it is registered in your name and account. If it is not, ask the current holder to transfer it to you; many extensions block transfers for 60 days after a registration or previous transfer.
Do I need separate email hosting? +
Usually it is best. A dedicated email service such as Google Workspace or Microsoft 365 is more reliable than the mailboxes bundled with basic hosting, and it keeps email working if you change website host.
Do I have to pay for an SSL certificate? +
Usually not. Free certificates from Let’s Encrypt are widely used and most good hosts include HTTPS at no extra cost.
Should I choose .com or a country domain? +
Choose .com if you serve customers internationally, and a country domain such as .co.th if you are clearly local and eligible. Many businesses register both and redirect one to the other.
