Connect your domain: DNS guides by provider

IONOS

ionos.com → Menu → Domains & SSL → your domain → Actions (three dots, or a gear) → DNS

1. 1. Open the DNS page of your domain

   Go to ionos.com and sign in. Click Menu in the title bar → Domains & SSL (some screens say Domain & SSL). Find yourbusiness.com; under Actions click the three dots (on some screens a gear) → DNS.

2. 2. Disconnect the domain if the buttons are greyed out

   Greyed-out buttons mean the domain is connected to the IONOS website builder (MyWebsite) or to an App Center app. Builder: Menu → Websites & Stores → Manage Website → next to Domain click the action icon → Disconnect Domain; it must now read No domain connected. App (Click & Build WordPress): Websites & Stores → Manage website → gear next to Domain → Change domain and pick another domain or subdomain first. Then come back to DNS. Buttons already active? Skip this step.

3. 3. Edit the A record for the root

   There must be exactly one A record for the root domain (Host name @ or empty). On that row, under Actions click the pencil → Edit record. In Points to replace the address with 147.182.236.145. Leave TTL. Click Save. A second A record for the root? Delete it.

4. 4. Make sure www exists as a subdomain

   Back in Domains & SSL, under Actions → Manage subdomains. If www isn't listed, click Create Subdomain, type www, Save. Listed already? Go on.

5. 5. Add the www CNAME

   Back in DNS for yourbusiness.com: Add record → CNAME. Host name www. Points to sites.remobuilds.com (no http://, no slash, no trailing dot). Save. If IONOS refuses because an A record for www already exists, delete that record first, then add the CNAME.

6. 6. Come back and check

   Press Check my domain here. IONOS applies the change at once; the rest of the internet usually follows within an hour, rarely longer. Your IONOS email keeps working: these two records don't touch it.

Watch out

• Never delete or edit MX or TXT rows: that is your email. Leave an A row named mail alone too.
• Only one A record for the root. IONOS can't change the Host name of an existing A record: edit its Points to.
• Never click Reset domain: it resets nameservers, A/AAAA, TXT, SRV and MX records at once and can't be undone (it breaks Google or Microsoft email).
• A CNAME never goes on the root domain.
• Changing nameservers makes IONOS lose control of the records and your email stops: never.
• Labels drift between IONOS pages (DNS / DNS Settings, Points to / Point to, three dots / gear): trust what you see.
