The Time To Live (TTL) determines how long old DNS records remain valid. You can adjust this flexibly. However, not all nameservers take this into account. It can therefore take up to 48 hours for your DNS to be distributed worldwide.
Configuring DNS (Existing Domains)
Learn how to configure DNS settings via the Customer Control Panel (CCP) and save DNS records.
These instructions apply to existing domains. For newly registered domains with CloudDNS, you can find the instructions at: Configuring DNS (CloudDNS)
These instructions are intended for experienced individuals only. Please note that improper execution may result in malfunctions or undesirable effects.
It is possible to use netcup domains with netcup products such as servers, SOGo, or web hosting without making any DNS changes. Please refer to the linked instructions for more information.
1. Opening DNS Settings
You can adjust your domain's DNS records at any time. This is necessary, for example, to connect to web hosting or SOGo solutions from other providers.
- Log in to the Customer Control Panel (CCP).
- Go to the menu item Domains.
- Find the domain you want to make changes to and click on the Magnifying Glass Icon next to the domain.
- Then switch to the DNS tab.

CNAME Records
Type
Description
Additional Information
CNAME
Clones the DNS
of another domain.
- Cannot be created directly on
the main domain (@), as this
would cause conflicts with the
SOA and NS records. - A CNAME record can only be
created for a hostname if there
are no other DNS records for
that hostname. If another record
already exists for the hostname,
a CNAME cannot be added.
3. Modifying DNS Records
Saving Changes
- Edit your DNS records and click Save DNS Records.
- The system checks your entries for semantic correctness. Errors are displayed in a red box.

Resetting Changes
If you have made a mistake, you can simply reset the DNS records.
- Check the box next to Set standard DNS settings.
- Click Save DNS Records.
- The reset usually takes about 10 minutes.
