IONOS
Connect IONOS domains to Webflow sites through DNS configuration for custom domain hosting and management.

How to integrate IONOS with Webflow
Connecting your IONOS domain to Webflow gives you custom domain branding while keeping your domain registration separate from hosting. This setup lets you maintain IONOS email services while Webflow handles your website, and gives you control over DNS records for subdomains and other services.
You can connect through native DNS methods or API integration.
Use Webflow’s Quick Connect setup
Quick Connect handles DNS configuration automatically through integration between Webflow and IONOS. This method works for most IONOS accounts.
Start in your Webflow site settings under Publishing > Production > Custom domains. Enter your IONOS domain. Webflow detects IONOS as your registrar and offers Quick Connect if your account supports it.
Authorize Webflow to configure DNS records through your IONOS account.
Quick Connect handles:
A
record andCNAME
record configuration- Domain verification through
TXT
records - SSL certificate provisioning after DNS verification
If Quick Connect isn't available for your account, use manual DNS configuration instead.
Configure DNS manually
Manual DNS configuration gives you direct control over record setup. So you can add specific A
and CNAME
records through the IONOS control panel.
To manually configure your DNS, log into your IONOS account and access your domain's DNS settings under domain management. Select your domain and add these records:
A
record with hostname@
pointing to the IP address in your Webflow site settings (typically75.2.70.75
or99.83.190.102
)CNAME
record with hostnamewww
pointing tocdn.webflow.com
TXT
record for domain verification (provided in Webflow site settings)
DNS changes typically take several hours to propagate. After propagation completes, return to Webflow site settings to verify the connection. Webflow automatically provisions SSL certificates once verification completes.
You can also configure subdomains with additional CNAME
records, keep existing MX
records for IONOS email hosting and set up domain redirects in Webflow after initial connection.
Build with Webflow and IONOS APIs
Automating DNS configuration across multiple sites requires API access to both platforms. IONOS provides Developer APIs for managing domains, DNS settings, and SSL certificates. Create API credentials through the IONOS Developer Portal to access these endpoints.
Webflow's Data API provides site management capabilities. Combine both platform APIs to automate domain connection workflows.
This approach works for agencies managing multiple client sites. For example, script DNS record creation when onboarding several clients simultaneously.
Implementation requirements:
- Create IONOS API credentials through their Developer Portal
- Use Webflow's v2 API endpoints
- Test in development environments before production deployment
The native DNS configuration methods (Quick Connect or manual setup) handle most use cases without API complexity.
What you can build
Connecting IONOS domains with Webflow enables professional websites with custom branding while separating hosting from domain registration.
Some configurations you can set up:
- Separate email hosting from site hosting: Maintain IONOS
MX
records foremail@yourdomain.com
while routing web traffic to Webflow for your marketing site - Centralized hosting with distributed domain management: Configure DNS records individually for each client domain in IONOS, but run all sites on shared Webflow infrastructure that provisions SSL certificates and serves content through Webflow's CDN
- Subdomain routing without additional hosting: Add
CNAME
records in IONOS for subdomains likecampaign.yourdomain.com
pointing to your existing Webflow site, allowing campaign-specific pages to use custom subdomains - Remove Webflow subdomain from checkout URLs: DNS configuration routes your IONOS domain directly to Webflow's e-commerce infrastructure, displaying
yourdomain.com/checkout
instead ofyourdomain.webflow.io/checkout
.
Frequently asked questions
Several hours typically. DNS propagation depends on TTL values and how quickly servers worldwide update their caches.
Check your domain in an incognito browser window to verify propagation. If your Webflow site appears, DNS has propagated successfully. Webflow automatically provisions SSL certificates after verification.
