Nameservers determine where your DNS settings are hosted and managed. When a domain points to Unstoppable Domains’ default nameservers, you can manage DNS records, such as A Record, CNAME, MX, TXT, and forwarding, directly from your UD account.
If you switch to custom nameservers, DNS management will shift to the hosting provider or DNS service that operates the nameservers you enter.
Important: When custom nameservers are set you will be unable to use several features offered by Unstoppable Domains, including the ability to manage DNS records directly from your account.
Unstoppable Domains utilizes Google’s nameserver infrastructure for reliability, speed, and security.
You can update nameservers individually per domain or in bulk.
Single Domain: How to Add or Change Nameservers
Go to My Domains.

Click on the domain to open the domain management page.
In the left-hand menu, select Nameservers.

Choose between:
Default (Unstoppable Domains’ nameservers), or
Custom (nameservers from your hosting provider or DNS service)

Select Custom and enter the nameservers.
You must enter at least two nameservers, but you may add more by selecting Add Another Nameserver.

Once all nameservers are entered, click Update Nameservers.

A confirmation banner will appear indicating that your changes are queued to be processed.

Propagation Time
After updating nameservers, DNS propagation can take up to 24–48 hours, depending on global caching and your previous DNS configuration. Changes may appear sooner, but this timeframe is typical across the DNS system.
Bulk Update: How to Add or Change Nameservers for Multiple Domains
Go to the My Domains page.

Check the box next to each domain you want to update.

Click Actions.

Select Edit Nameservers.

Choose Use your own nameservers.

Enter the desired nameservers.
At least two nameservers are required; additional nameservers can be added using Add Another Nameserver.
Press Save.
Propagation Time
As with single-domain updates, bulk changes may take 24–48 hours to fully propagate.
Reverting to Default Nameservers
You can revert nameservers back to Unstoppable Domains’ defaults individually or in bulk.
Follow the same steps above, but choose Default (for single domains)

or select Use UD default nameservers during bulk editing.
