DNS is your domain's address book. Four record types cover almost everything:
- A — "this name lives at this server address". Your website needs one for
example.comand usually one forwww. - CNAME — "this name is an alias of another name". Handy for subdomains.
- MX — "email for this domain goes here". Created automatically when you enable email with us.
- TXT — free-form notes machines read: SPF/DKIM/DMARC (email trust) and ownership checks live here.
Editing records
If your domain uses our nameservers, edit everything under DNS in the portal. Changes go live in seconds. If a record exists twice, delete the stale one — the newest is not automatically preferred.
Rules of thumb
- Don't delete records you don't recognise while email works — MX/TXT often look obscure and matter most.
- TTL = how long the internet caches a record. Lower it before a planned move, raise it after.
