1&1 IONOS allows you to specify separate name servers for each domain instead of the default 1&1 IONOS name servers. This allows you to delegate DNS management for your domains to another provider or host your own name servers.
Setting Name Servers
You can change the name servers for the domain in the Control Panel.
- Select the desired domain and click on Nameserver under Actions.
Click Use Custom Name Servers and enter the desiredname servers in the Name Server 1andName Server 2fields. Optionally, you can enter two additional external name servers in the Name server 3andName server 4fields.
To apply the changes, click Save.
You can edit or reset the name servers in this area at any time.
To reset your name servers and use the 1&1 IONOS name servers again (default setting), click Reset Settings.
If you change the name servers, it can take up to 48 hours for the change to take effect everywhere due to the decentralized structure of the Domain Name System.
Effects of Using Your Own Name Servers
If you use your own name servers, you can configure additional DNS records for your domain in order to, for example, prepare changes to your own name servers. However, these records are not visible on the Internet. After your own name servers have been completely propagated on the Internet (max. 48 hours after the change due to the TTL), it is necessary that you make the DNS records with the provider concerned or in the external name server concerned.
