How to connect your IONOS subdomain to SleepPRO™
Connect a domain
Here is how to connect a subdomain of a domain at IONOS, such as courses.yoursleepbusiness.com.
First add your subdomain in SleepPRO™, as described in step 1 of Integrating your subdomain with SleepPRO™. Each subdomain gets its own CNAME records.
First CNAME record
- Open the DNS zone of your domain in IONOS and click Add a record.
- Choose CNAME.
- Enter your subdomain, such as courses, in Hostname.
- Enter the first value from SleepPRO™, ending in cloudfront.net, with the full stop at the end, in Points to.
- Click Save.
A CNAME record with this name already there? Edit its value instead.
Second CNAME record
- Click Add a record and choose CNAME.
- In Hostname, enter the code from SleepPRO™ which comes before your domain, starting with an underscore and ending with your subdomain.
- In Points to, enter the second value from SleepPRO™, ending in acm-validations.aws.
- Click Save.
Check your records
Go to dnschecker.org and enter the full name of each record, including your domain. You should see your value with a green tick. If not, review your DNS settings.
DNS changes take 24 to 48 hours to spread fully.
If IONOS will not save a record because of a conflict, usually with the first CNAME, ask IONOS support whether the existing record is needed or can be removed.
