A domain is your website's memorable address. Hosting stores the site's files and application data.
DNS settings connect the two. Domain registration and hosting can be separate services, even with different providers.
The three components
| Component | Szerepe |
|---|---|
| Domain registration | The right to use and renew the chosen name. |
| DNS management | Identifies which server handles the website or email. |
| Web hosting | Stores and serves the website. |
How do you connect them?
- Register the domain or verify access to your existing domain.
- Request the DNS details required for your hosting.
- Add the required records at the actual DNS provider.
- Check both page loading and HTTPS. Owning a domain alone does not mean there is a working website.
Can the domain, website and email use different providers?
Yes: the domain registrar, DNS operator, web host and email provider can all be separate. Moving a website therefore does not necessarily require changing registrar. Changing nameservers, however, affects the entire DNS zone: creating only website records at the new host can break email or other verifications.
- Copy all required records before changing nameservers, not just the A record.
- Check email MX and authentication records separately.
- Track domain and hosting renewals separately; paying for one does not necessarily renew the other.
If the domain exists but there is no website
| Observation | Next step |
|---|---|
| The domain does not resolve | Nameservers, DNS zone and the presence of the record. |
| A different site loads | A/AAAA/CNAME targets, virtual host assignment and caching. |
| A certificate error appears | The certificate name, chain and relevant website configuration. |
| The website works, but email does not | Email's separate DNS and mailbox settings. |
