RebelSites uses Entri to auto-configure your DNS — no manual record editing needed. When you click "Connect Domain" in the app, an Entri modal opens and handles everything automatically for Squarespace and most other registrars.
In RebelSites, go to your site settings and click "Connect a custom domain."
Enter your domain name.
Click "Connect" — the Entri modal will open.
Sign into your registrar when prompted.
Entri configures the DNS records automatically. Done.
The whole process takes about 30 seconds. If Entri can't connect to your registrar automatically, it will show you manual instructions instead.
If the automatic connection didn't work, follow these manual steps.
Go to account.squarespace.com → "Domains" (account level, not inside a website) → click your domain → "DNS."
Click "Add Record" → Type: CNAME | Host: www | Data: paste CNAME target → Save.
Delete any existing CNAME or A record for "www" that points to Squarespace's servers.
