How can I connect a subdomain (ad.kimberleyplastic.com.au) to a Webflow hosted site while keeping the main domain (kimberleyplastic.com.au) pointed elsewhere? I have already set up the subdomain with the Webflow A-Records.

TL;DR
  • Add the subdomain (ad.kimberleyplastic.com.au) in Webflow's Hosting settings to generate required DNS records.  
  • Configure A records for the subdomain to point to Webflow’s IPs (75.2.70.75 and 99.83.190.102), ensure no conflicting DNS entries, then verify connection and enable SSL in Webflow.

To connect a subdomain (ad.kimberleyplastic.com.au) to Webflow while keeping the main domain on a different hosting provider, you need to ensure DNS and Webflow project settings are configured correctly.

​

1. Update Webflow Project Settings

​

  • Go to Project Settings in your Webflow dashboard.
  • Navigate to the Hosting tab.
  • Scroll to the Custom Domains section.
  • Add your subdomain: ad.kimberleyplastic.com.au.
  • Webflow will generate the required DNS records for this subdomain.

​

2. Verify DNS Records for the Subdomain

​

Since you've already added Webflow's A-records, double-check the configuration:

​

  • The A records should be set on the subdomain (not the root domain).
  • Host: ad
  • Points to: (a) 75.2.70.75, (b) 99.83.190.102
  • Make sure there’s no conflicting CNAME, AAAA, or wildcard record for the subdomain.
  • TTL can typically be left at default (e.g., 3600 seconds or auto).

​

3. SSL and Domain Status Checks

​

  • Back in Webflow's Hosting tab, confirm that the domain shows a green “Connected” status.
  • If still pending, allow up to 48 hours for DNS propagation.
  • Enable SSL in Webflow if it’s not already on (required for HTTPS).

​

4. Set the Subdomain as the Default Domain (Optional)

​

  • If you want all traffic to that project to load under ad.kimberleyplastic.com.au, click “Make default” next to the subdomain in Webflow’s domain list.
  • This ensures canonical redirects and SEO consistency.

​

5. Keep Root Domain Unaffected

​

  • Because you're only updating the DNS for the subdomain, your primary domain (kimberleyplastic.com.au) remains pointed to its original provider.
  • Do not change the root domain’s A or CNAME records unless you want Webflow to control that too.

​

Summary

​

To connect ad.kimberleyplastic.com.au to Webflow while leaving kimberleyplastic.com.au elsewhere, make sure you (1) add the subdomain to Webflow Hosting settings, (2) point only the A records for “ad” to Webflow’s IPs, and (3) verify the domain connection in Webflow. This setup keeps the root domain unaffected.
