DNS (Domain Name System) connects your domain name to your website, email and other services. Most website and email problems after changes come from DNS settings.
Common records
| Record | Purpose |
|---|---|
| A | Points the domain to a server IP address |
| CNAME | Points a subdomain to another domain name |
| MX | Routes email to your email provider |
| TXT | Verification, SPF, DKIM, DMARC |
| NS | Which servers manage your DNS |
Where DNS is managed
Usually at your domain registrar, hosting provider or a DNS service like Cloudflare. Check the NS records to know which.
Changing DNS safely
- Screenshot or export existing records first.
- Change one thing at a time.
- Changes can take time to update worldwide.
- Do not delete MX records unless moving email.
