# Configure DNS Zones

The Portal for our DNS service lets you manage all aspects of your DNS zone.

We assume for this guide that you have already chosen a zone bundle. If you have not chosen a zone bundle yet, refer to the 
[quickstart]({{< ref "/product/networking/dns/quick-start/" >}}) to select one.

## Configuring a Zone via the Portal
Enter your domain name in the `Add a Domain` form and click on `Add` to add a name to the domains list.

If the status bar turns red, you cannot manage more
domains. To add more domains you need to upgrade your subscription to a 
[larger plan]({{< ref "/product/networking/dns/quick-start/" >}}).

Your domain name appears in the list of managed domains. Click on the domain name to display its records.

## Configuring a Domain with a Registrar
Before going any further with the zone configuration, check the domain name
configuration with your registrar. The name servers should be set to the NS records showing on the Exoscale Portal.
If the NS record is not set, any records you set up in the Portal will not be used.
